ESB project has two main functions
one is creating a ESB project for developing ESB by set up classpath
and another is deploying ESB project,
ESB register itself to AS runtime, is just for deploying project using
WTP deployment way.
Let me explain why there is a ESB specified classpath container:
Firstly, AS server runtime can not ensure that it can provide a proper
ESB runtime any time,
because not all JBoss Servers contain ESB runtime, if a user just want
set up a development environment by
a standalone ESB runtime and there is not a ESB specified classpath
container, how could he do?
Eh - how do you do if there is not an ESB in the
runtime ? You would be
in the same situation, right ?
Currently, there are two options for creating ESB classpath container,
1. get ESB runtime jars from specified AS runtime
2. get jars from a specified ESB runtime which predefined in
preference page.
for now, AS classpath container is used as non-facet related
classpath, I don't think it can pick up jars
for all project facet, there maybe JBossWS facet, it need JBossWS
runtime, JBoss ESB facet need
ESB runtime, and Seam facet Seam runtime, AS classpath container
almost don't know where the
location and structure of an new added runtime.
Seam facet is not doable because
Seam jar's are not part of the AS
runtime (it is "outside" and needs deploying inside the app),
ESB and WS are all "inside" the AS runtime and AS could calculate these.
btw. I think all of this is more for jbosstools-dev than SOA tools since
it is not soa specific.
If AS classpath container can provide a extension point for new facet
and runtime, every new facet
just need extend the extension point by providing a jars calculation
logic and AS runtime pick jars
from extensions. that would be good.
Yes - maybe runtime components can do this
?

For current ESB project, there are two separate
functions, the first one
is setting ESB runtime classpath for the project, and another is
deployment. two functions have dependency on project target server
runtime, but the two dependencies are different, Setting esb runtime
classpath is just ensure that the project can
compile against ESB. if the project target runtime does not contain
an ESB runtime, users can provide a predefined JBoss ESB runtime, so
users can write esb code at least, but if ESB project tight couple with
project target runtime server, users can do nothing without setting
target runtime correctly.

I do not see how this requires a different ESB classpath container and
especially since you would really
like to make sure that users compile against the same thing they deploy
against.
In what situations today is an ESB project useful without having a

I do not see how this requires a different ESB classpath container and
especially since you would really

deploy against.
Yes, a reasonable logic should be that, but users might deploy
the
project to any server which runtime
supports the project facet, as far as I know, wtp deployment does not
have limitation that the project only can be deployed
to the project's target server, that means the project target server
runtime has nothing to do with the deployment,
so it maybe hard to ensure that users compile against the same thing
they deploy against.
In what situations today is an ESB project useful without having a
targeted runtime ?
Users can select a predefined standalone ESB runtime, so they
can
program and then deploy,
not sure if it's the best logic, maybe ask the server runtime pick up
jars is a good solution.

Denny,
Max and I discussed this, and for the time being (this release), we'd
just like to move the ESB cp container ahead of the AS cp container on
the project classpath. This will allow override libs in the ESB
classpath container to be loaded first.
Is this possible, and, if so, can you take care of this?

John and Max, today ESB cp container has been being in front of AS cp
container on ESB project classpath, after you
create a esb project, you can look at the .classpath file, the default
order is that the ESB cp container is in front of AS cp.
There might be a problem for a ESB client project, users might create a
Java project as ESB client project and then
add ESB and AS library to the project with wrong order manually, so the
wrong scout.jar would be loaded.

okey, sounds good...so what was the cause of the original error ?
Does it just work outside the box ?

That is something the user can fix then.

How to change the order of classpaths ? Press F1 :)
With respect to more specifically in ESB then sure, find a good spot in
the ESB docs and add it in.

How to change the order of classpaths ? Press F1 :)
You might laugh, but in a previous life I dealt with a product team that
was convinced users are not going to know about F1, and thus wanted big
"Help" buttons added all over the product. ;)
With respect to more specifically in ESB then sure, find a good spot
in the ESB docs and add it in.
Yes, specifically about the jars we know are impacted: scout and juddi.
Denny: Can you coordinate getting this information added to the JBDS ESB

okey, sounds good...so what was the cause of the original error ?
Does it just work outside the box ?
The original error maybe caused by the ESB
client example projects,
it seems that ESB and AS cp container of the ESB client projects
have the wrong order, I will update all ESB project and client project
examples with the right classpath order.

That is something the user can fix then.
We can help by creating a "ESB client project" wizard (or facet?)
I
don't think creating a "ESB client project" wizard or facet can solve
this problem, since the ESB client can be any types of
project, such as java project, ESB project and sometimes it's might be a
J2ee project, all need to for ESB client is just adding
ESB classpath to the project, so I think we can just provide a popup
menu "Set Up ESB Classpath" by pop up a wizard to select
all available ESB classpath container.

I don't think creating a "ESB client project" wizard or facet can
solve this problem, since the ESB client can be any types of
project, such as java project, ESB project and sometimes it's might be
a J2ee project, all need to for ESB client is just adding
ESB classpath to the project,
The same can be said about any type of java project
in eclipse - they
can all be configured manually if you want ;)
It would solve it in the sense users could see how it should work - but
if we don't need a ESB client project then i'm fine with that;
I think there are too many specialized project wizards in eclipse already ;)
so I think we can just provide a popup menu "Set Up ESB
Classpath" by
pop up a wizard to select
all available ESB classpath container.
I don't understand what that does
differently than adding ESB classpath
under standard classpath dialog for java projects ?

Yes, a reasonable logic should be that, but users might deploy the
project to any server which runtime
supports the project facet, as far as I know, wtp deployment does not
have limitation that the project only can be deployed
to the project's target server, that means the project target server
runtime has nothing to do with the deployment,
so it maybe hard to ensure that users compile against the same thing
they deploy against.
afaik, the server needs to support your ESB facet to deploy
it.

Users can select a predefined standalone ESB runtime, so they can
program and then deploy,
not sure if it's the best logic, maybe ask the server runtime pick up
jars is a good solution.
Sure, I'm not saying to *remove* the ESB classpath container, but I'm
saying that in the case of
the runtime is *embedded* inside the server runtime it would make sense
that the server runtime
provides the classpath instead of the separate ESB classpath container.
But lets get back to seeing what we can do now.
We haven't heard why there are different .jar's yet but I guess the
thing we can do know is to ensure that the ESB classpath container
gets added in front of the server runtime - that should solve this
issue, right ?
