In this example, j2ee4cxw is using two separate business interfaces. One for remote and one for local. That should not be a problem as far as i know. Feel free to correct me, if i am wrong :) j2ee4cxw, I don't see anything obvious in your code, which might result in this exception. anonymous wrote : ServiceLocator.getEJB(SHIPPER_JNDI_NAME); Can you post the code in the getEJB method of ServiceLocator? And how frequently do you see this exception? Every time you use the local interface? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4161259#...
