I am using maven to build applications.

I have deployed a WAR file containing many common jars as shared library in application server.

I have an artifact (say A-EJB) of packaging type EJB. I have built the ejb jar file.

I have an another artifact (say A-EAR) of packaging type EAR.

I have added A-EJB dependency in pom file of A-EAR. I could build the EAR file and for adding shared library reference, I have added library reference in weblogic-application.xml of EAR.

In my final EAR file, I could see A-EJB.jar file, other dependency jar files of A-EAR artifact.

EAR structure:

————–APP-INF\lib\some jars
————–META-INF\application.xml, MANIFEST.MF, weblogic-application.xml
————–A-ejb.jar

The class files of A-EJB.jar requires reference of common jars in shared library.

Ideally, I am expecting the deployment should happen successfully but this is not happening. Even though I have shared library reference in EAR file, the deployment fails due to classNotFoundException while preparing the EJB module during deployment.

The class files of A-EJB.jar searches for required jar files for reference but they are available in shared library and shared library is not used even EAR file has the reference to it.

Exception:

weblogic.application.ModuleException: Exception preparing module: EJBModule
[EJB:011023]An error occurred while reading the deployment descriptor. The error was:
…………………………………………………..

Caused By: java.lang.ClassNotFoundException:
……………………………………………………

So, this means even though EAR had a shared library reference, the ejb.jar present inside the EAR did not have reference to shared library. Is this true ?

Has anyone faced this exception and scenario. Kindly help me about resolving this issue.
