Hey Ian,
(Adding windup-dev.)
I'm not really sure what this issue could be, but it worries me that you needed to add
a method to FurnaceService. What did you add? You can't ask Furnace for an instance of
a type that is not a Service. (It wouldn't know how to construct it.)
The last error you received worries me specifically because it makes me think that there
is something funky going on with the ClassLoader hierarchy itself, and that is never good;
however, it could be due to some kind of quirk with what you added (it also may be a bug),
so I think I need to see what you are doing.
Could you show me where this code is so that I can take a look?
Thanks!
~Lincoln

Subject: Furnace not finding Windup FileService
Lincoln,
I can not figure out why Furnance is reporting that it can not find the Windup FileService
despite the fact that it is reporting it loaded the graph-api addon. Any ideas?
Please see attached for the log. It clearly shows the graph-api addon being loaded. And I
have verified that addon contains the graph-api.jar which contains the FileService. I have
tried to debug the furnace stuff but I keep running into source not found issues and
getting lost. I have been able to tell that ImportedImpl#getExportedInstances is getting
called and it is looping over the graph-api addon. But it does not seem to find the class
in there, but I have not been able to debug into furnace beyond that point.
Looking at the variable state the WeldServiceRegistery instance for the graph-api addon
shows the FIleService there. For some reason it is just not being retrevied. I have
attached a screenshoot of the variable state from within
ImportedImpl#getExportedInstances. Can you think of any reason
serviceRegistry.getExportedInstances(type) would be failing giving all of this?

New subject: Furnace not finding Windup FileService
Lincoln,
Sorry. I just saw this. My email filters took over when you added the windup mailing list
and it got filtered out of my main inbox.
The Furnace method I added was:
public <S> S lookupType(Class<S> service) {
S instance = null;
if (furnace != null) {
Set<Class<S>> types = null;
types = furnace.getAddonRegistry().getExportedTypes(service);
if (types != null && !types.isEmpty()) {
for(Class<S> type : types) {
try {
instance = type.newInstance();
break;
} catch (Exception e) {
e.getMessage();
//skip to next instance if this one did not work
}
}
}
}
return instance;
}
My issue was with loading "FileService.class". Calling "lookup" could
not find it, but calling my new "lookupType" it could find it.
Blue Skies,
~Ian

Subject: Furnace not finding Windup FileService
Lincoln,
I can not figure out why Furnance is reporting that it can not find the Windup FileService
despite the fact that it is reporting it loaded the graph-api addon. Any ideas?
Please see attached for the log. It clearly shows the graph-api addon being loaded. And I
have verified that addon contains the graph-api.jar which contains the FileService. I have
tried to debug the furnace stuff but I keep running into source not found issues and
getting lost. I have been able to tell that ImportedImpl#getExportedInstances is getting
called and it is looping over the graph-api addon. But it does not seem to find the class
in there, but I have not been able to debug into furnace beyond that point.
Looking at the variable state the WeldServiceRegistery instance for the graph-api addon
shows the FIleService there. For some reason it is just not being retrevied. I have
attached a screenshoot of the variable state from within
ImportedImpl#getExportedInstances. Can you think of any reason
serviceRegistry.getExportedInstances(type) would be failing giving all of this?

Ah, well one issue is that the "*ModelServices" like FileService are not
actually Furnace services.. That's unfortunate... Do you need access to the
FileService?

Sorry. I just saw this. My email filters took over when you added the
windup mailing list and it got filtered out of my main inbox.
The Furnace method I added was:
public <S> S lookupType(Class<S> service) {
S instance = null;
if (furnace != null) {
Set<Class<S>> types = null;
types = furnace.getAddonRegistry().getExportedTypes(service);
if (types != null && !types.isEmpty()) {
for(Class<S> type : types) {
try {
instance = type.newInstance();
break;
} catch (Exception e) {
e.getMessage();
//skip to next instance if this one did not work
}
}
}
}
return instance;
}
My issue was with loading "FileService.class". Calling "lookup" could
not
find it, but calling my new "lookupType" it could find it.

Hey Ian,
(Adding windup-dev.)
I'm not really sure what this issue could be, but it worries me that you
needed to add a method to FurnaceService. What did you add? You can't ask
Furnace for an instance of a type that is not a Service. (It wouldn't know
how to construct it.)
The last error you received worries me specifically because it makes me
think that there is something funky going on with the ClassLoader hierarchy
itself, and that is never good; however, it could be due to some kind of
quirk with what you added (it also may be a bug), so I think I need to see
what you are doing.
Could you show me where this code is so that I can take a look?
Thanks!
~Lincoln

Lioncoln,
Looking here,
http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/...,
and
debuging through eclipse without source, I have figured out it is choking
on like 189. It appears this #getExportedInstances method is only for
loading beans. I see a #getExportedType which is what I am guessing I need,
but the only Furnace API I see is FurnaceService.INSTANCE.lookup(clazz)
which ends up doing this bean lookup rather then a type lookup. Am I
missing something here? Is there just missing API to look up a type and not
a bean via Furnace?

New subject: Furnace not finding Windup FileService
Hey Ian,
I've pushed up some "work" on the Windup Eclipse Plugin. I've simplified
the dependencies, updated to Windup 2.2.0.Final, and removed dependencies that I do not
believe belong in the OSGi bundles.
https://github.com/windup/windup-eclipse-plugin/tree/windup2-lincoln
Unfortunately I am not an OSGi expert, and I am getting an exception that I'm hoping
you can help me with. I need to know why this class is not being exported from the
"org.jboss.tools.forge.runtime" bundle, or why it is not being imported where it
should be. We don't have this problem with the Forge Eclipse Plugin, so something must
be different with our imports/exports. I tried to add this manually in several places, but
to no avail. (See trace below message.)
I think that we will have more success if we are in more constant communication about
these issues. You can help with the OSGi issues, I can help with the Furnace issues, and
the team can help add new APIs that you'll need to do your work.
My recommendation once we get this CNFE resolved (assuming that's the last issue with
what's currently in my branch,) is that we begin building specific interfaces for use
in the Eclipse plugin and provide them via a Windup service. I also recommend sticking
entirely to interfaces where possible. That will make this go a lot more smoothly because
Furnace is really best at proxying interfaces across the ClassLoader boundary. Proxying
concrete classes is never really safe because you can't always guarantee a
sane/proxiable inheritance hierarchy.
What are your thoughts?

I'm not really sure what this issue could be, but it worries me that you needed to add
a method to FurnaceService. What did you add? You can't ask Furnace for an instance of
a type that is not a Service. (It wouldn't know how to construct it.)

I have verified that the Furnace add on 'org-jboss-windup-graph-windup-graph' is
being loaded and contains the windup-frames JAR so I am not clear why furnace is not able
to load the class.

Lioncoln,
Looking here,
http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/...
, and debuging through eclipse without source, I have figured out it is choking on like
189. It appears this #getExportedInstances method is only for loading beans. I see a
#getExportedType which is what I am guessing I need, but the only Furnace API I see is
FurnaceService.INSTANCE.lookup(clazz) which ends up doing this bean lookup rather then a
type lookup. Am I missing something here? Is there just missing API to look up a type and
not a bean via Furnace?

Subject: Furnace not finding Windup FileService
Lincoln,
I can not figure out why Furnance is reporting that it can not find the Windup FileService
despite the fact that it is reporting it loaded the graph-api addon. Any ideas?
Please see attached for the log. It clearly shows the graph-api addon being loaded. And I
have verified that addon contains the graph-api.jar which contains the FileService. I have
tried to debug the furnace stuff but I keep running into source not found issues and
getting lost. I have been able to tell that ImportedImpl#getExportedInstances is getting
called and it is looping over the graph-api addon. But it does not seem to find the class
in there, but I have not been able to debug into furnace beyond that point.
Looking at the variable state the WeldServiceRegistery instance for the graph-api addon
shows the FIleService there. For some reason it is just not being retrevied. I have
attached a screenshoot of the variable state from within
ImportedImpl#getExportedInstances. Can you think of any reason
serviceRegistry.getExportedInstances(type) would be failing giving all of this?

New subject: Furnace not finding Windup FileService
Hi Lincoln,
I have done some work on this over the past few days. Most of the work
was me banging my head on the wall learning Eclipse and how the forge
tools interact with it. :)
But I believe that I have made significant progress. Here is the first PR:
https://github.com/jbosstools/jbosstools-forge/pull/139
This enables the export of the Proxy interface (and other methods within
the same package). If you include code in WindupRuntimePlugin that
references these classes, you will see a compile error from the tycho
compiler's OSGI validator. That's because the previous export didn't
export the full package (including subpackages) for some reason, and it
doesn't work at runtime either.
I have pushed my changes to the plugin here:
https://github.com/windup/windup-eclipse-plugin/tree/windup2-jess
The current error is as follows:

This one actually seems pretty clear. I think the real fix here is to
quit exposing so much to the client, but rather to expose a more
friendly API service. I will work on that soon.

Hey Ian,
I've pushed up some "work" on the Windup Eclipse Plugin. I've
simplified the dependencies, updated to Windup 2.2.0.Final, and
removed dependencies that I do not believe belong in the OSGi bundles.
https://github.com/windup/windup-eclipse-plugin/tree/windup2-lincoln
Unfortunately I am not an OSGi expert, and I am getting an exception
that I'm hoping you can help me with. I need to know why this class is
not being exported from the "org.jboss.tools.forge.runtime" bundle, or
why it is not being imported where it should be. We don't have this
problem with the Forge Eclipse Plugin, so something must be different
with our imports/exports. I tried to add this manually in several
places, but to no avail. (See trace below message.)
I think that we will have more success if we are in more constant
communication about these issues. You can help with the OSGi issues, I
can help with the Furnace issues, and the team can help add new APIs
that you'll need to do your work.
My recommendation once we get this CNFE resolved (assuming that's the
last issue with what's currently in my branch,) is that we begin
building specific interfaces for use in the Eclipse plugin and provide
them via a Windup service. I also recommend sticking entirely to
interfaces where possible. That will make this go a lot more smoothly
because Furnace is really best at proxying interfaces across the
ClassLoader boundary. Proxying concrete classes is never really safe
because you can't always guarantee a sane/proxiable inheritance hierarchy.
What are your thoughts?

Sorry. I just saw this. My email filters took over when you added
the windup mailing list and it got filtered out of my main inbox.
The Furnace method I added was:
public <S> S lookupType(Class<S> service) {
S instance = null;
if (furnace != null) {
Set<Class<S>> types = null;
types = furnace.getAddonRegistry().getExportedTypes(service);
if (types != null && !types.isEmpty()) {
for(Class<S> type : types) {
try {
instance = type.newInstance();
break;
} catch (Exception e) {
e.getMessage();
//skip to next instance if this one did not work
}
}
}
}
return instance;
}
My issue was with loading "FileService.class". Calling "lookup"
could not find it, but calling my new "lookupType" it could find it.

Hey Ian,
(Adding windup-dev.)
I'm not really sure what this issue could be, but it worries me
that you needed to add a method to FurnaceService. What did you
add? You can't ask Furnace for an instance of a type that is not a
Service. (It wouldn't know how to construct it.)
The last error you received worries me specifically because it
makes me think that there is something funky going on with the
ClassLoader hierarchy itself, and that is never good; however, it
could be due to some kind of quirk with what you added (it also
may be a bug), so I think I need to see what you are doing.
Could you show me where this code is so that I can take a look?
Thanks!

I have verified that the Furnace add on
'org-jboss-windup-graph-windup-graph' is being loaded and contains
the windup-frames JAR so I am not clear why furnace is not able to
load the class.
Ideas?

Lioncoln,
Looking here,
http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/...,
and
debuging through eclipse without source, I have figured out it is
choking on like 189. It appears this #getExportedInstances method
is only for loading beans. I see a #getExportedType which is what
I am guessing I need, but the only Furnace API I see
is FurnaceService.INSTANCE.lookup(clazz) which ends up doing this
bean lookup rather then a type lookup. Am I missing something
here? Is there just missing API to look up a type and not a bean
via Furnace?
Blue Skies,
~Ian

*Subject: *Furnace not finding Windup FileService
Lincoln,
I can not figure out why Furnance is reporting that it can not
find the Windup FileService despite the fact that it is reporting
it loaded the graph-api addon. Any ideas?
Please see attached for the log. It clearly shows the graph-api
addon being loaded. And I have verified that addon contains the
graph-api.jar which contains the FileService. I have tried to
debug the furnace stuff but I keep running into source not found
issues and getting lost. I have been able to tell that
ImportedImpl#getExportedInstances is getting called and it is
looping over the graph-api addon. But it does not seem to find the
class in there, but I have not been able to debug into furnace
beyond that point.
Looking at the variable state the WeldServiceRegistery instance
for the graph-api addon shows the FIleService there. For some
reason it is just not being retrevied. I have attached a
screenshoot of the variable state from
within ImportedImpl#getExportedInstances. Can you think of any
reason serviceRegistry.getExportedInstances(type) would be failing
giving all of this?
~Ian

New subject: Furnace not finding Windup FileService
Ok, I pushed a fix for the graphcontext issue below. Reports can be
generated now, although I suspect there are still plenty of other bugs.
Feel free to give it a try!

Hi Lincoln,
I have done some work on this over the past few days. Most of the work
was me banging my head on the wall learning Eclipse and how the forge
tools interact with it. :)
But I believe that I have made significant progress. Here is the first PR:
https://github.com/jbosstools/jbosstools-forge/pull/139
This enables the export of the Proxy interface (and other methods
within the same package). If you include code in WindupRuntimePlugin
that references these classes, you will see a compile error from the
tycho compiler's OSGI validator. That's because the previous export
didn't export the full package (including subpackages) for some
reason, and it doesn't work at runtime either.
I have pushed my changes to the plugin here:
https://github.com/windup/windup-eclipse-plugin/tree/windup2-jess

This one actually seems pretty clear. I think the real fix here is to
quit exposing so much to the client, but rather to expose a more
friendly API service. I will work on that soon.

Ok, my PR for jbosstools caused issues, but fortunately gastaldi fixed
them. :)
This all appears to work now! Thanks everyone!

New subject: Furnace not finding Windup FileService
Jess and Lincoln,
You all are my heros!
I will take what you all have done and merge in and see where we are at tonight!
Licoln, did you solve your OSGi error yet? If not that should be a simple fix. And yes, I
need the FIleService.
~Ian

Ok, my PR for jbosstools caused issues, but fortunately gastaldi fixed them. :)
This all appears to work now! Thanks everyone!

Hi Lincoln,
I have done some work on this over the past few days. Most of the work was me banging my
head on the wall learning Eclipse and how the forge tools interact with it. :)
But I believe that I have made significant progress. Here is the first PR:
https://github.com/jbosstools/jbosstools-forge/pull/139
This enables the export of the Proxy interface (and other methods within the same
package). If you include code in WindupRuntimePlugin that references these classes, you
will see a compile error from the tycho compiler's OSGI validator. That's because
the previous export didn't export the full package (including subpackages) for some
reason, and it doesn't work at runtime either.
I have pushed my changes to the plugin here:
https://github.com/windup/windup-eclipse-plugin/tree/windup2-jess

This one actually seems pretty clear. I think the real fix here is to quit exposing so
much to the client, but rather to expose a more friendly API service. I will work on that
soon.

Hey Ian,
I've pushed up some "work" on the Windup Eclipse Plugin. I've simplified
the dependencies, updated to Windup 2.2.0.Final, and removed dependencies that I do not
believe belong in the OSGi bundles.
https://github.com/windup/windup-eclipse-plugin/tree/windup2-lincoln
Unfortunately I am not an OSGi expert, and I am getting an exception that I'm hoping
you can help me with. I need to know why this class is not being exported from the
"org.jboss.tools.forge.runtime" bundle, or why it is not being imported where it
should be. We don't have this problem with the Forge Eclipse Plugin, so something must
be different with our imports/exports. I tried to add this manually in several places, but
to no avail. (See trace below message.)
I think that we will have more success if we are in more constant communication about
these issues. You can help with the OSGi issues, I can help with the Furnace issues, and
the team can help add new APIs that you'll need to do your work.
My recommendation once we get this CNFE resolved (assuming that's the last issue with
what's currently in my branch,) is that we begin building specific interfaces for use
in the Eclipse plugin and provide them via a Windup service. I also recommend sticking
entirely to interfaces where possible. That will make this go a lot more smoothly because
Furnace is really best at proxying interfaces across the ClassLoader boundary. Proxying
concrete classes is never really safe because you can't always guarantee a
sane/proxiable inheritance hierarchy.
What are your thoughts?

Hey Ian,
(Adding windup-dev.)
I'm not really sure what this issue could be, but it worries me that you needed to add
a method to FurnaceService. What did you add? You can't ask Furnace for an instance of
a type that is not a Service. (It wouldn't know how to construct it.)
The last error you received worries me specifically because it makes me think that there
is something funky going on with the ClassLoader hierarchy itself, and that is never good;
however, it could be due to some kind of quirk with what you added (it also may be a bug),
so I think I need to see what you are doing.
Could you show me where this code is so that I can take a look?
Thanks!

Lioncoln,
Looking here,
http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/...
, and debuging through eclipse without source, I have figured out it is choking on like
189. It appears this #getExportedInstances method is only for loading beans. I see a
#getExportedType which is what I am guessing I need, but the only Furnace API I see is
FurnaceService.INSTANCE.lookup(clazz) which ends up doing this bean lookup rather then a
type lookup. Am I missing something here? Is there just missing API to look up a type and
not a bean via Furnace?

Lincoln,
I can not figure out why Furnance is reporting that it can not find the Windup FileService
despite the fact that it is reporting it loaded the graph-api addon. Any ideas?
Please see attached for the log. It clearly shows the graph-api addon being loaded. And I
have verified that addon contains the graph-api.jar which contains the FileService. I have
tried to debug the furnace stuff but I keep running into source not found issues and
getting lost. I have been able to tell that ImportedImpl#getExportedInstances is getting
called and it is looping over the graph-api addon. But it does not seem to find the class
in there, but I have not been able to debug into furnace beyond that point.
Looking at the variable state the WeldServiceRegistery instance for the graph-api addon
shows the FIleService there. For some reason it is just not being retrevied. I have
attached a screenshoot of the variable state from within
ImportedImpl#getExportedInstances. Can you think of any reason
serviceRegistry.getExportedInstances(type) would be failing giving all of this?

New subject: Furnace not finding Windup FileService
Ian,
Thanks! We it would have been a long hard road to get here without your
work :) The OSGi error is solved as long as you have the most recent
JBossTools Forge master (it didn't make it into the JBDS 8.1 release.)
What do you need FileService for? We'll need to introduce an API in the
windup tooling API for what you need.

Hi Lincoln,
I have done some work on this over the past few days. Most of the work was
me banging my head on the wall learning Eclipse and how the forge tools

But I believe that I have made significant progress. Here is the first PR:
https://github.com/jbosstools/jbosstools-forge/pull/139
This enables the export of the Proxy interface (and other methods within
the same package). If you include code in WindupRuntimePlugin that
references these classes, you will see a compile error from the tycho
compiler's OSGI validator. That's because the previous export didn't export
the full package (including subpackages) for some reason, and it doesn't
work at runtime either.
I have pushed my changes to the plugin here:
https://github.com/windup/windup-eclipse-plugin/tree/windup2-jess
The current error is as follows:

This one actually seems pretty clear. I think the real fix here is to quit
exposing so much to the client, but rather to expose a more friendly API
service. I will work on that soon.

Hey Ian,
I've pushed up some "work" on the Windup Eclipse Plugin. I've
simplified
the dependencies, updated to Windup 2.2.0.Final, and removed dependencies
that I do not believe belong in the OSGi bundles.
https://github.com/windup/windup-eclipse-plugin/tree/windup2-lincoln
Unfortunately I am not an OSGi expert, and I am getting an exception
that I'm hoping you can help me with. I need to know why this class is not
being exported from the "org.jboss.tools.forge.runtime" bundle, or why it
is not being imported where it should be. We don't have this problem with
the Forge Eclipse Plugin, so something must be different with our
imports/exports. I tried to add this manually in several places, but to no
avail. (See trace below message.)
I think that we will have more success if we are in more constant
communication about these issues. You can help with the OSGi issues, I can
help with the Furnace issues, and the team can help add new APIs that
you'll need to do your work.
My recommendation once we get this CNFE resolved (assuming that's the
last issue with what's currently in my branch,) is that we begin building
specific interfaces for use in the Eclipse plugin and provide them via a
Windup service. I also recommend sticking entirely to interfaces where
possible. That will make this go a lot more smoothly because Furnace is
really best at proxying interfaces across the ClassLoader boundary.
Proxying concrete classes is never really safe because you can't always
guarantee a sane/proxiable inheritance hierarchy.
What are your thoughts?

Ah, well one issue is that the "*ModelServices" like FileService are not
actually Furnace services.. That's unfortunate... Do you need access to the
FileService?

Ian,
Thanks! We it would have been a long hard road to get here without your
work :) The OSGi error is solved as long as you have the most recent
JBossTools Forge master (it didn't make it into the JBDS 8.1 release.)
What do you need FileService for? We'll need to introduce an API in the
windup tooling API for what you need.

New subject: Furnace not finding Windup FileService
Liconln,
Should I be looking at your branch on git?
Do i need to run with the latest version of furenace?
Just trying to get my environment set up the same as yours so it works for me too :)
Now that you got the hard part working I want to add bells and whistles :)

Thanks! We it would have been a long hard road to get here without your work :) The OSGi
error is solved as long as you have the most recent JBossTools Forge master (it didn't
make it into the JBDS 8.1 release.)
What do you need FileService for? We'll need to introduce an API in the windup tooling
API for what you need.

Hi Lincoln,
I have done some work on this over the past few days. Most of the work was me banging my
head on the wall learning Eclipse and how the forge tools interact with it. :)
But I believe that I have made significant progress. Here is the first PR:
https://github.com/jbosstools/jbosstools-forge/pull/139
This enables the export of the Proxy interface (and other methods within the same
package). If you include code in WindupRuntimePlugin that references these classes, you
will see a compile error from the tycho compiler's OSGI validator. That's because
the previous export didn't export the full package (including subpackages) for some
reason, and it doesn't work at runtime either.
I have pushed my changes to the plugin here:

This one actually seems pretty clear. I think the real fix here is to quit exposing so
much to the client, but rather to expose a more friendly API service. I will work on that
soon.

Hey Ian,
I've pushed up some "work" on the Windup Eclipse Plugin. I've simplified
the dependencies, updated to Windup 2.2.0.Final, and removed dependencies that I do not
believe belong in the OSGi bundles.
https://github.com/windup/windup-eclipse-plugin/tree/windup2-lincoln
Unfortunately I am not an OSGi expert, and I am getting an exception that I'm hoping
you can help me with. I need to know why this class is not being exported from the
"org.jboss.tools.forge.runtime" bundle, or why it is not being imported where it
should be. We don't have this problem with the Forge Eclipse Plugin, so something must
be different with our imports/exports. I tried to add this manually in several places, but
to no avail. (See trace below message.)
I think that we will have more success if we are in more constant communication about
these issues. You can help with the OSGi issues, I can help with the Furnace issues, and
the team can help add new APIs that you'll need to do your work.
My recommendation once we get this CNFE resolved (assuming that's the last issue with
what's currently in my branch,) is that we begin building specific interfaces for use
in the Eclipse plugin and provide them via a Windup service. I also recommend sticking
entirely to interfaces where possible. That will make this go a lot more smoothly because
Furnace is really best at proxying interfaces across the ClassLoader boundary. Proxying
concrete classes is never really safe because you can't always guarantee a
sane/proxiable inheritance hierarchy.
What are your thoughts?

The Furnace method I added was:

My issue was with loading "FileService.class". Calling "lookup" could
not find it, but calling my new "lookupType" it could find it.

Hey Ian,
(Adding windup-dev.)
I'm not really sure what this issue could be, but it worries me that you needed to add
a method to FurnaceService. What did you add? You can't ask Furnace for an instance of
a type that is not a Service. (It wouldn't know how to construct it.)
The last error you received worries me specifically because it makes me think that there
is something funky going on with the ClassLoader hierarchy itself, and that is never good;
however, it could be due to some kind of quirk with what you added (it also may be a bug),
so I think I need to see what you are doing.
Could you show me where this code is so that I can take a look?
Thanks!

I have verified that the Furnace add on 'org-jboss-windup-graph-windup-graph' is
being loaded and contains the windup-frames JAR so I am not clear why furnace is not able
to load the class.

Subject: Re: Furnace not finding Windup FileService
Lioncoln,
Looking here,
http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/...
, and debuging through eclipse without source, I have figured out it is choking on like
189. It appears this #getExportedInstances method is only for loading beans. I see a
#getExportedType which is what I am guessing I need, but the only Furnace API I see is
FurnaceService.INSTANCE.lookup(clazz) which ends up doing this bean lookup rather then a
type lookup. Am I missing something here? Is there just missing API to look up a type and
not a bean via Furnace?

Subject: Furnace not finding Windup FileService
Lincoln,
I can not figure out why Furnance is reporting that it can not find the Windup FileService
despite the fact that it is reporting it loaded the graph-api addon. Any ideas?
Please see attached for the log. It clearly shows the graph-api addon being loaded. And I
have verified that addon contains the graph-api.jar which contains the FileService. I have
tried to debug the furnace stuff but I keep running into source not found issues and
getting lost. I have been able to tell that ImportedImpl#getExportedInstances is getting
called and it is looping over the graph-api addon. But it does not seem to find the class
in there, but I have not been able to debug into furnace beyond that point.
Looking at the variable state the WeldServiceRegistery instance for the graph-api addon
shows the FIleService there. For some reason it is just not being retrevied. I have
attached a screenshoot of the variable state from within
ImportedImpl#getExportedInstances. Can you think of any reason
serviceRegistry.getExportedInstances(type) would be failing giving all of this?

Hi Ian,
You should be able to work from master. I've just merged the latest changes.

You will need the latest version of the forge-eclipse-plugin.
Thanks!

Thanks! We it would have been a long hard road to get here without

What do you need FileService for? We'll need to introduce an API
in the windup tooling API for what you need.

Hi Lincoln,
I have done some work on this over the past few days.
Most of the work was me banging my head on the wall
learning Eclipse and how the forge tools interact with
it. :)
But I believe that I have made significant progress.
Here is the first PR:
https://github.com/jbosstools/jbosstools-forge/pull/139
This enables the export of the Proxy interface (and
other methods within the same package). If you include
code in WindupRuntimePlugin that references these
classes, you will see a compile error from the tycho
compiler's OSGI validator. That's because the previous
export didn't export the full package (including
subpackages) for some reason, and it doesn't work at
runtime either.
I have pushed my changes to the plugin here:

This one actually seems pretty clear. I think the real
fix here is to quit exposing so much to the client,
but rather to expose a more friendly API service. I
will work on that soon.

Hey Ian,
I've pushed up some "work" on the Windup Eclipse
Plugin. I've simplified the dependencies, updated
to Windup 2.2.0.Final, and removed dependencies
that I do not believe belong in the OSGi bundles.
https://github.com/windup/windup-eclipse-plugin/tree/windup2-lincoln
Unfortunately I am not an OSGi expert, and I am
getting an exception that I'm hoping you can help
me with. I need to know why this class is not
being exported from the
"org.jboss.tools.forge.runtime" bundle, or why it
is not being imported where it should be. We don't
have this problem with the Forge Eclipse Plugin,
so something must be different with our
imports/exports. I tried to add this manually in
several places, but to no avail. (See trace below
message.)
I think that we will have more success if we are
in more constant communication about these issues.
You can help with the OSGi issues, I can help with
the Furnace issues, and the team can help add new
APIs that you'll need to do your work.
My recommendation once we get this CNFE resolved
(assuming that's the last issue with what's
currently in my branch,) is that we begin building
specific interfaces for use in the Eclipse plugin
and provide them via a Windup service. I also
recommend sticking entirely to interfaces where
possible. That will make this go a lot more
smoothly because Furnace is really best at
proxying interfaces across the ClassLoader
boundary. Proxying concrete classes is never
really safe because you can't always guarantee a
sane/proxiable inheritance hierarchy.
What are your thoughts?

My issue was with loading "FileService.class".
Calling "lookup" could not find it, but
calling my new "lookupType" it could find it.

Hey Ian,
(Adding windup-dev.)
I'm not really sure what this issue could be,
but it worries me that you needed to add a
method to FurnaceService. What did you add?
You can't ask Furnace for an instance of a
type that is not a Service. (It wouldn't know
how to construct it.)
The last error you received worries me
specifically because it makes me think that
there is something funky going on with the
ClassLoader hierarchy itself, and that is
never good; however, it could be due to some
kind of quirk with what you added (it also may
be a bug), so I think I need to see what you
are doing.
Could you show me where this code is so that I
can take a look?
Thanks!
~Lincoln

I have verified that the Furnace add on
'org-jboss-windup-graph-windup-graph' is being
loaded and contains the windup-frames JAR so I
am not clear why furnace is not able to load
the class.
Ideas?

Lioncoln,
Looking here,
http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/...,
and
debuging through eclipse without source, I
have figured out it is choking on like 189. It
appears this #getExportedInstances method is
only for loading beans. I see a
#getExportedType which is what I am guessing I
need, but the only Furnace API I see
is FurnaceService.INSTANCE.lookup(clazz) which
ends up doing this bean lookup rather then a
type lookup. Am I missing something here? Is
there just missing API to look up a type and
not a bean via Furnace?

Lincoln,
I can not figure out why Furnance is reporting
that it can not find the Windup FileService
despite the fact that it is reporting it
loaded the graph-api addon. Any ideas?
Please see attached for the log. It clearly
shows the graph-api addon being loaded. And I
have verified that addon contains the
graph-api.jar which contains the FileService.
I have tried to debug the furnace stuff but I
keep running into source not found issues and
getting lost. I have been able to tell that
ImportedImpl#getExportedInstances is getting
called and it is looping over the graph-api
addon. But it does not seem to find the class
in there, but I have not been able to debug
into furnace beyond that point.
Looking at the variable state the
WeldServiceRegistery instance for the
graph-api addon shows the FIleService there.
For some reason it is just not being
retrevied. I have attached a screenshoot of
the variable state from
within ImportedImpl#getExportedInstances. Can
you think of any
reason serviceRegistry.getExportedInstances(type)
would be failing giving all of this?

What do you need FileService for? We'll need to introduce an API in the windup tooling

But I believe that I have made significant progress. Here is the first PR:
https://github.com/jbosstools/jbosstools-forge/pull/139
This enables the export of the Proxy interface (and other methods within the same
package). If you include code in WindupRuntimePlugin that references these classes, you
will see a compile error from the tycho compiler's OSGI validator. That's because
the previous export didn't export the full package (including subpackages) for some
reason, and it doesn't work at runtime either.

This one actually seems pretty clear. I think the real fix here is to quit exposing so
much to the client, but rather to expose a more friendly API service. I will work on that
soon.

Hey Ian,
I've pushed up some "work" on the Windup Eclipse Plugin. I've simplified
the dependencies, updated to Windup 2.2.0.Final, and removed dependencies that I do not
believe belong in the OSGi bundles.
https://github.com/windup/windup-eclipse-plugin/tree/windup2-lincoln
Unfortunately I am not an OSGi expert, and I am getting an exception that I'm hoping
you can help me with. I need to know why this class is not being exported from the
"org.jboss.tools.forge.runtime" bundle, or why it is not being imported where it
should be. We don't have this problem with the Forge Eclipse Plugin, so something must
be different with our imports/exports. I tried to add this manually in several places, but
to no avail. (See trace below message.)
I think that we will have more success if we are in more constant communication about
these issues. You can help with the OSGi issues, I can help with the Furnace issues, and
the team can help add new APIs that you'll need to do your work.
My recommendation once we get this CNFE resolved (assuming that's the last issue with
what's currently in my branch,) is that we begin building specific interfaces for use
in the Eclipse plugin and provide them via a Windup service. I also recommend sticking
entirely to interfaces where possible. That will make this go a lot more smoothly because
Furnace is really best at proxying interfaces across the ClassLoader boundary. Proxying
concrete classes is never really safe because you can't always guarantee a
sane/proxiable inheritance hierarchy.

Ah, well one issue is that the "*ModelServices" like FileService are not
actually Furnace services.. That's unfortunate... Do you need access to the
FileService?

Lincoln,
Sorry. I just saw this. My email filters took over when you added the windup mailing list
and it got filtered out of my main inbox.
The Furnace method I added was:
public <S> S lookupType(Class<S> service) {
S instance = null;
if (furnace != null) {
Set<Class<S>> types = null;
types = furnace.getAddonRegistry().getExportedTypes(service);
if (types != null && !types.isEmpty()) {
for(Class<S> type : types) {
try {
instance = type.newInstance();
break;
} catch (Exception e) {
e.getMessage();
//skip to next instance if this one did not work
}
}
}
}
return instance;
}
My issue was with loading "FileService.class". Calling "lookup" could
not find it, but calling my new "lookupType" it could find it.

Hey Ian,
(Adding windup-dev.)
I'm not really sure what this issue could be, but it worries me that you needed to add
a method to FurnaceService. What did you add? You can't ask Furnace for an instance of
a type that is not a Service. (It wouldn't know how to construct it.)
The last error you received worries me specifically because it makes me think that there
is something funky going on with the ClassLoader hierarchy itself, and that is never good;
however, it could be due to some kind of quirk with what you added (it also may be a bug),
so I think I need to see what you are doing.
Could you show me where this code is so that I can take a look?
Thanks!

I have verified that the Furnace add on 'org-jboss-windup-graph-windup-graph' is
being loaded and contains the windup-frames JAR so I am not clear why furnace is not able
to load the class.
Ideas?

Subject: Re: Furnace not finding Windup FileService
Lioncoln,
Looking here,
http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/...
, and debuging through eclipse without source, I have figured out it is choking on like
189. It appears this #getExportedInstances method is only for loading beans. I see a
#getExportedType which is what I am guessing I need, but the only Furnace API I see is
FurnaceService.INSTANCE.lookup(clazz) which ends up doing this bean lookup rather then a
type lookup. Am I missing something here? Is there just missing API to look up a type and
not a bean via Furnace?

Subject: Furnace not finding Windup FileService
Lincoln,
I can not figure out why Furnance is reporting that it can not find the Windup FileService
despite the fact that it is reporting it loaded the graph-api addon. Any ideas?
Please see attached for the log. It clearly shows the graph-api addon being loaded. And I
have verified that addon contains the graph-api.jar which contains the FileService. I have
tried to debug the furnace stuff but I keep running into source not found issues and
getting lost. I have been able to tell that ImportedImpl#getExportedInstances is getting
called and it is looping over the graph-api addon. But it does not seem to find the class
in there, but I have not been able to debug into furnace beyond that point.
Looking at the variable state the WeldServiceRegistery instance for the graph-api addon
shows the FIleService there. For some reason it is just not being retrevied. I have
attached a screenshoot of the variable state from within
ImportedImpl#getExportedInstances. Can you think of any reason
serviceRegistry.getExportedInstances(type) would be failing giving all of this?
~Ian
