a deployment problem

[gufiya]

Hello,

I'm trying a very simple scenario of deploying and undeploying EJB project from Eclipse.

I have created 3 projects -
1) EJB project
2) EAR project
3) EJB client project

I deploy the EAR to JBOSS server, and everything looks fine:

17:13:32,812 INFO [EJBContainer] STARTED EJB: titan.travelagent.TravelAgentBean ejbName: TravelAgentBean
17:13:32,828 INFO [EJB3Deployer] Deployed: file:/C:/jboss-4.2.3/server/default/deploy/TitanEAR.ear/TitanEJB.jar/
17:13:32,828 INFO [EARDeployer] Started J2EE application: file:/C:/jboss-4.2.3/server/default/deploy/TitanEAR.ear/

When I look in the deploy directory, I see a directory for my EAR file, which contains three things:
1) a directory for the EJB project (class files)
2) a meta-inf directory for the EAR project (with "application.xml")
3) a jar-file for the EJB client project (only a jar file, not directory)

My problem starts when I remove the EAR project using Eclipse.
For some reason, the client-jar-file (item 3 above) is not removed from the server. This cause exception in JBOSS since it tries to redeploy the EAR application but "application.xml" was deleted already.

I guess it is really stupid thing, but for me this stuff is quite new.
Any ideas?

Thanks

any chance something inside your app is holding a lock on the jar ?

What happens if you stop eclipse - can you remove the file then ?

Thank you for your quick reply.

I don't have any jar file in the workspace -
I guess that the jar is created during the deplyoment to the server's "deploy" directory.
Anyway, the problem happens also after restarting (Eclipse & machine).

For some reason, EJB client project is deployed as a jar file, but the EJB project itself (beans implementation) is deployed as group of flat files... maybe this is the root of the problem?

I would need some more details to be able to reproduce this ? Anything in the error log view ?

I'm using JBoss 4.2.3GA, Eclipse 3.3.2 (for J2EE).
I have also added to eclipse JBoss Tools 2.1.2.

When I deploy the EAR, everything is fine, and error log stays clean.
When I remove the EAR from the server, the client JAR remains on the server, I cannot delete it (until I shutdown JBoss), and I receive the following error log entry:

Another important lead:
I have found a workaround.
1) Go to the EJB project preferences -> j2ee module dependencies.
2) Remove the dependency with the Client JAR project.
3) close the preferences window (otherwise step 5 will not work).
4) Go to the EJB project preferences -> Java build path.
5) Add a dependency with the Client JAR project.

Now everything works with no problem.
