Reusing @Remote interface in two J2EE applications

We have a main application and a client application deployed on Glassfish 3.1. The main application invokes the client application through a JNDI lookup over a @Remote开发者_开发技巧 interface. Now we tried to deploy another client application that uses the same @Remote interface, hoping to be able to invoke both applications but just changing target EJB name. However, we received the following exception:

Caused by: java.lang.RuntimeException: Error while binding JNDI name com.company.ClientRemote for EJB : Client2
    at com.sun.ejb.containers.BaseContainer.initializeHome(BaseContainer.java:1550)
    at com.sun.ejb.containers.StatelessSessionContainer.initializeHome(StatelessSessionContainer.java:202)

    at org.glassfish.ejb.startup.EjbApplication.loadContainers(EjbApplication.java:234)
    ... 67 more
Caused by: javax.naming.NameAlreadyBoundException: Use rebind to override

Both clients need to have a common functionality, and this functionality is used by the main application when it invokes the clients.

How do you suggest to go around this?

Thanks!
