I am struggling from 2 days to find out the root cause for an EAR deployment issue.

I have  a EAR which is having a ejb jar (core.jar) which has all ejb files and another jar (no WAR file).

EAR has 2 jars in it (one is a EJB specific jar and other is a normal jar)

When I am trying to deploy this in Weblogic 10 server, I am getting the below mentioned error

 

[EJB:011023]An error occurred while reading the deployment descriptor. The error was:
 : java.lang.NullPointerException..
weblogic.application.ModuleException: Exception preparing module: EJBModule(CORE-1.0-SNAPSHOT.jar)
