EJB3.0 can not separate stateles bean from its interface!

[begimot]

I couldn't find similar topic so I am opening a new one.

I have an ejb.jar. Inside it I have one stateless bean. The bean interface is putted in separate jar - ejb-interface.jar. I am using maven and it packages the both jars inside ear.jar

+ear.jar
+ejb.jar
+ejb-interface.jar

No I am trying to deploy the ear on jbos-4.2.1GA and I got the following exception:a

15:04:15,562 WARN [ServiceController] Problem starting service jboss.j2ee:service=EJB3,module=ejb.jar
java.lang.NoClassDefFoundError: "The path to the interface".

Why it does not find the interface? I can not find where is the problem?

Sorry the name of the topic is misleading. It must be:
EJB3.0, I can not separate stateless bean from its interface!

Ok, I found a solution. In the application.xml I marked ejb-interface.jar as an ejb module.

But I don't understand why it is not possible just to move out the ejb interfaces, as so and so they will be use by other modules.
