location of ejb-jar and weblogic-ejb-jar for ANT build?

I am building an EJB Project where I am creating a simple MDB that recieves a JMS message and prints it using Weblogic.

I am using ANT to build the JAR file and deploy that JAR as a module to Weblogic. I use no special ANT tasks and build the code as a normal JAR.

This process completes smoothly but the EJB doesn't read the message from the Queue. I doubt if I have put the ejb-jar and weblogic-ejb-jar under the correct folder.

My folder structure looks like below

1. Project Folder
2. Project Folder/src/package/EJBClass
3. Project Folder/xmls : I copy the XMLs here
4. Project Folder/war/classes
5. Project Folder/war/lib

As you see I am using a normal Java project to build the JAR. Is the directory structure wrong ?

Thanks
