Need Help in Deploying a EAR File and WAR file in the Same Node

[sudheerchandracse]

Hi all,

I have a ear file(say abc.ear) and war file(say bcd.war). bcd.war uses the Jars that are present in the abc.ear.

When I deploy both ear and war file in single nodein JBOSS 4.2.2. GA, , it is throwing an error saying " Unsuccessful Deployments" in the console while starting the server.

But if i deploy both ear and war file in two different nodes, its working fine.

Do I need to configure anything in node for deploying an ear and war in a single node.

Please helpme in solving this issue.

Thanks in Advance.

Could you attach the logfile?

If the WAR use classes from a JAR inside the EAR it might be that the classloader prevent that the class is visible from the WAR.

See http://community.jboss.org/wiki/ClassLoadingOverview and http://community.jboss.org/wiki/ClassLoadingConfiguration

Fink,

Thanks for the Reply. Please find the attached log file.

Please Note that War has some Jars, EAR has some JARs. There are some same Jars present in both EAR and WAR.

It looks like that you remove classes needed by your configuration or you use the wrong configuration.

and later on:

What do you change in your JBoss configuration and which one do you use as base?

[sudheerchandracse]

We are using the jboss version, jboss-4.2.2.GA.We downloaded from the jboss site and we changed the CallByValue to true in conf/jboss-service.xml and deploy/ear-deployer.xml. This is the only change we did in the installed Jboss.

Is there any change needed or is there any configurtaion required to make the classes available ?
