EAR Classloader
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi,
what classloader hierarchy does geronimo implement for EAR archives?
I have an EAR archive I want to deploy. It contains some JAR libraries
and a WAR archive. But when the WAR archive is loaded and the
application is started than I get some CNF exceptions for classes which
reside in the JAR libraries. Note that the jar files are no EJB modules.
Thanks
Markus Wolf

Yes there is code besides the WAR achive, otherwise I would deploy just
a single WAR application. :)
The JAR libraries contain Hibernate POJOs and business logic used by
different clients.
Is there a lib dir in EAR archives like the one in WAR files? I've found
no documentation for it.

Is there any other code in this EAR, or just the WAR and these set of JARs?,
If yes so I think you can put the JARs in the lib dir for this EAR, or you
can put them under the repository dir and mention that you depend on them.

Is the classloading behaviour without adding the Classpath in MANIFEST.MF
a bug in 1.1rc1 ? Should I file a Jira?

Re: EAR Classloader
Posted by Mario Rübsam <mr...@coderesearch.com>.
I had a working EAR for 1.0 with this structure
app.ear/
app.jar
cpa.jar
found.jar
webclient.war
I referenced the jars from the webclient.war/META-INF/MANIFEST.MF
Classpath: app.jar cpa.jar found.jar
When I deploy this EAR in G 1.1-rc1 I get ClassNotFoundExceptions.
When I put the JARs into the webclient.war/WEB-INF/lib everything
work fine. But this is not an option because I have some other
WARs to deploy in that EAR.
A general class loading and dependency resolution description for
EARs would be very helpful.
The next thing I found out is that the DB connector dependency
must be placed into the geronimo-application.xml when deploying
as an EAR. When deploying as an WAR the dependency is good in
geronimo-web.xml as stated in the docs or the console example.
Thanks,
Mario

1 not 1.1
I can't get my app to deploy in 1.1 for other reasons but if adding jars
to the mainfest classpath is broken in 1.1 this is a fairly serious bug.

Which G version are you running because in 1.1-rc1 adding the jars to
the war MANIFEST classpath stopped working for me?
Thanks,

Re: EAR Classloader
Posted by pa...@targetgroup.net.
What you had to do isn't geronimo specific, just part of J2EE. If you use
WSAD or RAD when you right click on a Web project and do properties, the
manifest classpath is set via the Java Jar dependencies tab. What you had
was a terribly common problem, as there is a difference between the
classpath you need to compile, and the one you need to run an app, hence
the two different classpaths.

I've added the jar files to the WARs MANIFEST.MF classpath and then it
does work.
I wasn't aware that adding files to the WAR classpath is supported.
Maybe this could be added to the documentation for the deployment on
geronimo.
Thanks for your great help.

Did you mean define them as manifest dependencies for the EAR archive,
or for the WAR archive?
Currently I have not defined them as dependencies which may cause the
problems, but I thought from the docs that all jars in an EAR are added
to the classloader hierarchy.

The jars are in the root of the EAR archive, because they are common
libraries which are not only used in the WAR application.
If I put them also in the WEB-INF/lib directory it does work, but I
think there will be classloading issues at a later time and also this is
a duplication of the compiled code inside the EAR file.
I would deploy the JAR libraries as EJB archives, but there are no EJBs
inside, and I do need a descriptor which needs at least one EJB...

Hi Markus...
Where these jars are deployed?, do they reside under the
<WEB_APP_DIR>/WEB-INF/lib directory or what?, generally for a web
application, referenced jars should reside under this dir or more common lib
dir, the one of the web container for example.
