I am trying to run a ANT build script on my application code and it gives ClassCastException in one of the classes in the weblogic.jar file. I have attached the stack trace in this forum. The problem here is that when i run the build script with EJB version 2.1 in my ejb-jar.xml it works perfectly fine and it creates the EAR file and gets deployed and even the application runs fine. But when i change the EJB version in my ejb-jar.xml to 3.0, i get a ClassCastException while running the build script. I am using SessionBeans(Stateless), EntityBeans(Container type) and MessageDrivenBeans in my application.


The stacktrace is something like this :

Hi,
I am trying to run a ANT build script on my application code and it gives ClassCastException in one of the classes in the weblogic.jar file. I have attached the stack trace in this forum. The problem here is that when i run the build script with EJB version 2.1 in my ejb-jar.xml it works perfectly fine and it creates the EAR file and gets deployed and even the application runs fine. But when i change the EJB version in my ejb-jar.xml to 3.0, i get a ClassCastException while running the build script.

The entry in my ejb-jar.xml is something like this :
