Drools Runtime unclear how to correctly define
----------------------------------------------
Key: JBIDE-3670
URL: https://jira.jboss.org/jira/browse/JBIDE-3670
Project: Tools (JBoss Tools)
Issue Type: Bug
Components: drools
Affects Versions: 3.0.0.cr1
Environment: jbdevstudio-linux-gtk-2.0.0.CR2-R200901250322.jar on RHEL 5, jdk
1.5.11
Reporter: Jeff DeLong
I tested out the Drools IDE in JBDS. I used the Drools icon to create a new Drools
project, and ran the DroolsTest class the wizard created as a Java Application. I got the
following exception:
java.lang.NoClassDefFoundError: org/antlr/runtime/CharStream
The problem is with defining the "Drools Runtime". As part of the setup for
creating a Drools Project for the first time, the user is asked to create a "Drools
Runtime". This is new (in the past Drools IDE new which set of jars to use), to be
consistent with other tools and allow user to select different Drools Runtimes. The
challenge for the user is how to define a Drools Runtime. You can either find the jars in
JBDS plugins, explode them into a folder, and point to them, or download Drools
engine/expert (in this case I had decided to try jboss-brms-engine-5.ea.zip, since this is
the .com version). However when this is unzipped, some jars are in the root of the folder
and some are in a lib directory. At least four of the ones in the lib directory are
required for runtime (antlr-runtime-3.1.1.jar, core-3.4.2.v_883_R34x.jar, mvel2-2.0.5.jar,
xstream-1.3.1.jar), and the jars in a subdirectory are not added to the runtime
classpath.
It should be easier for the user to define a Drools Runtime. They should not have to know
about which jars to move around. They should just be able to download and unzip.

Kris Verlaenen commented on JBIDE-3670:
---------------------------------------
Jeff,
Thanks for the feedback. What would you suggest as a solution for this? I can easily
modify the Drools runtime to not only search for jar files in the runtime directory
itself, but also in its sub-directories (and so on). This would solve the problem here,
but wouldn't this create the risk of adding jars that we actually didn't want to
add,, just because they are in a sub-directory somewhere? Another option would be to only
look for a lib dir in the runtime directory, this would solve the problem if you use a
binary Drools download of some sort (as that adds external dependencies in a lib jar and
the drools jars in the top-level directory).
By the way, the easiest solution for the end user at this point is to just let the IDE
create a runtime for him (it will extract the necessary jars from the plugin itself to the
selected runtime directory), as described here:

------------------------------------
Kris,
Thanks for pointing me at the documentation. It was not clear (to me anyway) how to use
the Create a new Drools 5 Runtime to create one with the jars that were packaged with the
IDE.
I think looking in the lib dir of the runtime directory makes sense; as that is how Drools
has been packaged for quite some time.

using the jars from the plugin is not what we can use for the product since the jars might
be different.
If SOA-P is usable with drools why aren't there some combinations of jars we can use
from it ?

---------------------------------------
How do other projects that define runtimes handle the fact when no runtime is defined?
People can easily remove the Drools container and replace it by whatever collection of
jars, so I'm not sure what the critical issue is now, other than that is not trivial
for a user to get the drools runtime from SOA-P (as he would need to manually select all
the necessary jars in SOA-P, which might be at different locations) but this could be
explained in documentation?

--------------------------------------------
The problem is that I would like things to just work in JBDS without having to do any
additional setup (that is the whole purpose of devstudio ;)
If SOA-P does not contain a set of jars how can drools apps even run on the server ?
With respect to the wizard then Drools is a bit different since it does not use the WTP
facet stuff which would allow you to delegate the jar resolvement to the server runtime,
i.e. for Seam we just want to know the runtime location to resolve the templates needed
for seam-gen and all other libs are fetched from the runtime or copied to the server. But
eventually it all comes down to that there seem to be no good way of me to grab some jars
from SOA-P and call that i.e. soa-p 4.3 drools runtime.

5 Runtime button. A minor issue with this is the way the box is organized. It says
"Either select an existing Drools Runtime on your file system or create a new
one" Then provides text boxes to fill in Name: and Path as well as a button
"Create a new Drools 5 Runtime". While the text I quoted is correct, the
organization of the UI still leave a bit of doubt as to whether they should fill in the
Name: and Path: and then push the Create a new Drools 5 Runtime Button. (as it turns out
it does not matter as the wizard assigns the name without regard to what the user types as
will require the user to browse to a folder if not supplied. When the use returns from
2) Use the Name: and Path and browse to a downloaded unzipped set of Drools jars. In
this case the problem was that some of the jars were in the lib directory, however Kris
fixed the wizard to add the lib directory as well.
The UI is a bit awkward because it is not clear exactly how the buttons and text fields
are used together. So for example, if you fill in the Name: and Path: you don't hit
the Create button. The directions in the documentation Kris pointed at are pretty clear,
but how would the user have access to this documentation?
3) Browse to a jbrules.esb directory. The issues here is that the MVEL jars are in another
.esb folder. Also, unless the user manually replaces them (which may be a requirement with
the initial JBoss BRMS release, the jars are for Drools4. So the user would have to
organize these jars into some other folder themselves.

Project: Tools (JBoss Tools)
Issue Type: Bug

Priority: Critical
Fix For: 3.0.0.GA
I tested out the Drools IDE in JBDS. I used the Drools icon to create a new Drools
project, and ran the DroolsTest class the wizard created as a Java Application. I got the
following exception:
java.lang.NoClassDefFoundError: org/antlr/runtime/CharStream
The problem is with defining the "Drools Runtime". As part of the setup for
creating a Drools Project for the first time, the user is asked to create a "Drools
Runtime". This is new (in the past Drools IDE new which set of jars to use), to be
consistent with other tools and allow user to select different Drools Runtimes. The
challenge for the user is how to define a Drools Runtime. You can either find the jars in
JBDS plugins, explode them into a folder, and point to them, or download Drools
engine/expert (in this case I had decided to try jboss-brms-engine-5.ea.zip, since this is
the .com version). However when this is unzipped, some jars are in the root of the folder
and some are in a lib directory. At least four of the ones in the lib directory are
required for runtime (antlr-runtime-3.1.1.jar, core-3.4.2.v_883_R34x.jar, mvel2-2.0.5.jar,
xstream-1.3.1.jar), and the jars in a subdirectory are not added to the runtime
classpath.
It should be easier for the user to define a Drools Runtime. They should not have to know
about which jars to move around. They should just be able to download and unzip.

--------------------------------------------
About #3 then the idea for the multiple runtimes was that it also supports Drools 4 (so if
the ui says differently we should change that).
If you can tell me exactly which jars would make sense to have in a "SOA-P Drools 4
Runtime" then let me know and we will have it preconfigured in JBDS so users
don't even need to take these decisions when they already have SOA-P installed.

btw. I agree the drools runtime creation ui is a bit hard to figure out. It took me a
couple of tries to realize that I have to click "Create new folder" in the
browse dir to get a new folder. If I just type the name and press Ok it simply just dumps
the jars in my home dir (a general problem with the os specific dir selector)

Is drools-api.jar required? It doesn't exist within the SOA platform.
If drools-api.jar isn't required, DroolsClasspathContainer needs to be changed to
recognize Drools Runtime libraries within the SOA platform.
Attached is a patch against org.drools.eclipse tag 5.0.0.24825.M5.
After applying this patch, I would be able to add a default Drools Runtime for those JBDS
users that have the SOA platform.

Thanks Snjezana.
I've added Kris and John as watchers so we can move the discussion we have had in
offline email to here instead.
Kris would the suggested patch be ok for you, or maybe something like that could be done
as an extension point ? i.e. a droolsruntimerecognizer or something which would be asked
before the default fallback of including everything ? If the recognizer returns null you
will ignore it.
This does not solve the problem if the server runtime changes location, but it will get
the job done at least and the recognizing would still work in your UI I presume.

---------------------------------------
The patch would indeed allow users to select the SOA-P directory as the path of the Drools
runtime. But it would also mean that we hardcode the specifics of how to find those jars
in our plugin, and I don't think that is a good idea. But an extension point could
possible solve this.
What do you mean by "when the server runtime changes location"? Could you
explain this use case Max?

If you move your server you can relocate it in the server editor.
This would invalidate the drools classpath container.
But it is probably not worth ensuring now.
btw. would probably be good if the classpath container gets stored with some id/path to
ensure it will always use the exact same "recognizer" ?

--------------------------------------
The patch would indeed allow users to select the SOA-P directory as
the path of the Drools runtime. But it would also mean that we
hardcode the specifics of how to find those jars in our plugin, and I don't think
that is a good idea.
I haven't changed the way the Drools classpath container works. I only added a
possibility to recognize the SOA platform as follows:
- the containers checks if there is the
"<PATH>/jboss-as/server/default/deploy/jbrules.esb" directory
- if the directory exists, the container adds libraries Kris mentioned
- it the directory doesn't exist, the container behaves as before
Max,
The Drools classpath container already contains a path that is used to add libraries.
That path can be changed using the Drools Runtime Preference page (when changing the
server location or the location of the SOA platform, for instance).

--------------------------------------------
I know the path can be changed in the drools ui - just would be nice if it was linked to
the actual SOA-P runtime, but that is for later.
My biggest concern is though that we ensure that once the runtime has been autorecognized
that it does not change.
i.e. how will we distinguish between looking for a Drools 4 runtime (what we do now) and
upcoming Drools 5 runtime in SOA-P ?
btw. does the ui still say Drools 5 runtime ? It should just be Drools runtime, right ?

---------------------------------------
The classpath container is just called Drools runtime.
I'm still not sure I understand the case you are trying to ensure. Let's suppose
the user has selected the SOA-P as path for the runtime. It will then autodetect the jars
in there (currently only the Drools4 runtime, if the next SOA-P release ships with Drools5
we'll have to add an extension that autodetects this Drools5 runtime. Will there ever
be a case where multiple runtimes can be detected from the same path (e.g. both Drools4
and Drools5 in the next SOA-P release)? If not, the jars will always remain the same,
because at most one recognizer will match.
Unless of course the user replaces his old SOA-P with a new one at the exact same
location, but is this a use case we really want to support (as in extremely unlikely as
the path name usually contains a version number)?

--------------------------------------------
Well how do you distinguish behavior differences if you don't know what version of
drools the user is targeting ?
with respect whether mutliple runtimes can be detected in the same location then I
don't know how SOA-P next version will look like obviously, but then that is not my
point. I want the classpath to be stable no matter what happens - it should not be
dynamic.
If the user wants to refresh his jars then he should explicitly ask for that IMO.

---------------------------------------
That just means that a Drools Runtime should not store the path, but a list of jars (full
path). The recognizers (the default one based on a path and the new SOA-P one discussed
here) would just autodetect that list.
So lets suppose I do the following:
- I create an extension point where recognizers can be registered, and I add the default
one (look in the selected directory and the lib folder) and the SOA-P one that Snjenzana
created
- I let the Drools runtime store the jars instead of the path
Would we then cover all the use cases correctly (for now, not taking the automatic linking
to for example the SOA-P runtime etc. into account)?

--------------------------------------
Other classpath containers (JBoss Runtime, Seam Runtime...) save the path and create a
list of libraries based on the path.
These containers are different for different releases (for instance, JBoss 5.0 Runtime had
to be changed when 5.0.0GA was released).
I am not sure why the Drools Runtime container would have to behave differently. Anyway,
we will have to change this container when releasing the next SOA-P.

--------------------------------------------
Kris - your suggestion sounds good.
Snjezana - I'm not sure what you mean...AS runtime classpath container is dynamically
calculated but based on knowing exactly which version we are dealing with; it should not
change.
I don't like the calculation but for now that is what WTP's server classpath
containers does. For Seam I disagree since these jars are copied to the project and there
are no classpath container at all.
Drools runtime is more like JDK runtime (which behaves by being automatic when defining,
but has the jars explicitly listed) and furthermore Drools runtime is not a simple thing
because SOA-P has no clear definition. And when the next SOA-P comes out we are not
changing the detection, we will be adding an additional one....hence why I wanted it to be
more explicit since I want to avoid too much magic ;)
btw. all of this would be so much easier if eclipse had all this stuff builtin and used a
more sane model of classpath setup....i.e. repository based - but that is for the next rev
;)

It is certainly the case that we expect users of SOA-P 4.3 to replace their jbrules.esb
4.0.7 jars with the corresponding ones from 5.0. Because Drools 5 (well JBoss BRMS 5.0 to
be exact) is going GA before SOA-P 4.3.FP1, and JBoss BRMS5 is supported on SOA-P 4.3), we
plan to provide instructions for users to upgrade their jbrules.esb folder with the
updated jars (include adding the MVEL2 jar to jbrules.esb (since it has different package
name than the original mvel-1.3.3-java1.5.jar that is in jbossesb. sar. At least this was
the plan last time Burr and discussed it.

engine/expert (in this case I had decided to try jboss-brms-engine-5.ea.zip, since this is
the .com version). However when this is unzipped, some jars are in the root of the folder
and some are in a lib directory. At least four of the ones in the lib directory are
required for runtime (antlr-runtime-3.1.1.jar, core-3.4.2.v_883_R34x.jar, mvel2-2.0.5.jar,
xstream-1.3.1.jar), and the jars in a subdirectory are not added to the runtime
classpath.
It should be easier for the user to define a Drools Runtime. They should not have to know
about which jars to move around. They should just be able to download and unzip.

--------------------------------------------
ok - sounds like a small nightmare ;)
In anyhow that makes it even more relevant to be able to edit the jars chosen by the
drools runtime.
Drools Runtime unclear how to correctly define
----------------------------------------------
Key: JBIDE-3670
URL: https://jira.jboss.org/jira/browse/JBIDE-3670
Project: Tools (JBoss Tools)
Issue Type: Bug
Components: drools
Affects Versions: 3.0.0.cr1
Environment: jbdevstudio-linux-gtk-2.0.0.CR2-R200901250322.jar on RHEL 5, jdk
1.5.11
Reporter: Jeff DeLong
Assignee: Snjezana Peco
Priority: Critical
Fix For: 3.0.0.GA
Attachments: DroolsClasspathContainer.patch
I tested out the Drools IDE in JBDS. I used the Drools icon to create a new Drools
project, and ran the DroolsTest class the wizard created as a Java Application. I got the
following exception:
java.lang.NoClassDefFoundError: org/antlr/runtime/CharStream
The problem is with defining the "Drools Runtime". As part of the setup for
creating a Drools Project for the first time, the user is asked to create a "Drools
Runtime". This is new (in the past Drools IDE new which set of jars to use), to be
consistent with other tools and allow user to select different Drools Runtimes. The
challenge for the user is how to define a Drools Runtime. You can either find the jars in
JBDS plugins, explode them into a folder, and point to them, or download Drools

---------------------------------------
I just did the changes as described earlier on Drools trunk:
- a Drools runtime now store a list of jars that it consists of
- added DroolsRuntimeRecognizer extension point to auto-detect these jars based on the
selected path when creating the runtime
- added a SOA-P 4.3 recognizer

--------------------------------------------
cool - now the question is: How do we get a build of that into JBT ? i.e. one where the
drools jars are available in maven so we can just use the appropriate tag ?
