Hi,
I'm being hit by https://bugs.eclipse.org/bugs/show_bug.cgi?id=241335 and
related bugs.
It seems that Ganymede introduced support for JEE 5's automatic pickup of
jar's in a lib folder by moving/copying
jars around instead of simply having users create a lib folder and put the
jars they would like to have in there.
And that (in my view natural use case) is actually causing problems with
how it is implemented in Ganymede
and my previous projects from 3.3 is being mangled by this.
What i'm looking for is if someone could tell me *how* the JEE 5 lib
folder as implemented in Ganymede
is *supposed* to work because I cannot make it to work....
Anyone with info on it ?
Thanks,
Max

You say it does like it does in WTP, but then my question is how is that
supposed to work ?
As far as I understand it listens to the manifest.mf and application.xml
which for JEE 5
is irellevant when you have a lib/ directory.
Thus I do not understand what the lib functionallity in WTP 3.0 is
supposed to do if
not just follow the JEE spec and pick up the jar's inside a lib/ directory
in your EarContents folder ?
Could you give me an example of EAR/EJB/WAR triaged project that utilizes
the lib/ directory folder
in WTP 3.0 ?

I think we covered this topic (or at least most of it) in bug 241335 after
comment #34.

Hi,
Being a little bit late to this discussion, I fully understand the point
Max made previously. Some kind of example project (or article/tutorial)
in webtool's community space on eclipse.org [1] would be really nice.
Most of this stuff although old is still relevant, but something on how
to effectively use the EAR/lib folder would be interesting.
I hope you don't mind me hijacking this thread for a similar question.
How are dependencies automatically added to the /lib folder of the EAR file?
Developing mostly with maven I usually play a lot with the
org.eclipse.wst.common.component file in the .settings directory of the
ear project. This is the underlying model for the "Java EE Module
Dependencies" project preference page if I understood correctly.
As the maven plugin I currently use [2] does not provide dependency
information to the ear project, I have to add dependencies manually to
this org.eclipse.wst.common.component file. The following example shows
a very small project with a dependency on spring:
<?xml version="1.0" encoding="UTF-8"?>
<project-modules id="moduleCoreId" project-version="1.5.0">
<wb-module deploy-name="amp-ear">
<wb-resource deploy-path="/" source-path="/EarContent"/>
<dependent-module deploy-path="/" handle="module:/resource/amp/amp">
<dependency-type>uses</dependency-type>
</dependent-module>
<dependent-module deploy-path="/lib"
handle="module:/classpath/var/M2_REPO/<path_to_spring>/spring-2.5.5.jar ">
<dependency-type>uses</dependency-type>
</dependent-module>
<!-- other dependencies -->
...
</project-modules>
(M2_REPO is a variable that points to the maven repository)
In this setup, the amp-ear project includes the EJB project amp and a
dependency on spring. This works just as expected: the spring.jar is
copied into the amp.ear/lib folder and found by the application server's
EAR classloader as soon as the application requests a corresponding class:
amp.ear
/lib
spring-2.5.5.jar
amp.jar
The problem is that I cannot add projects from the workspace directly
this way:
On the preference page it is possible to select the JAR/Module
corresponding to the project to be included in the dependencies of the
application. The last column is a checkbox to include this module in the
lib directory ("/lib"). This results in the following entry in
org.eclipse.wst.common.component:
<dependent-module archiveName="dep.jar" deploy-path="/lib"
handle="module:/resource/dep/dep">
<dependency-type>uses</dependency-type>
</dependent-module>
Where "dep" is the name of the project this application depends on.
Looks good, but in the resulting EAR file, the dep.jar is just dropped
into the root folder
amp.ear
/lib
spring-2.5.5.jar
amp.jar
dep.jar
I have tried different possibilities (archiveName="/lib/dep.jar",
deploy-path="/lib/dep.jar" ...), but none of them resulted in what I
expected.
Now, there are two options which are both not very helpful:
a) add dep.jar to the application's manifest
b) build dep.jar outside of eclipse and put it somewhere to be included
in /lib (the method discussed in this thread)
I hope I could explain my point. For me this seems like a bug, but I
could not find any references so I preferred asking here.
Thank you,
Kariem

Hello Kariem,
It seems you do it the right way, but unfortunately you hit some bugs like:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=241466
https://bugs.eclipse.org/bugs/show_bug.cgi?id=241332
https://bugs.eclipse.org/bugs/show_bug.cgi?id=254992
If you upgrade to WTP 3.0.3 that was released few days ago, your EAR should
*export* properly. But this might not be true for the *publishing*
(deployment). The generic server adapter in WTP uses different logic for
publishing than the logic for export and publishing has the above mentioned
problems. Therefore all server adapter that extend the generic one should
have the problem you describe.
Greetings,
Kaloyan
