    EJB exception logging

    Steven T. Pierson Newbie

      I have developed some EJBs which run fine under Weblogic. I am trying to move them to run under JBoss.

      I continue to get the following exception.
      java.lang.NullPointerException
      at org.jboss.ejb.plugins.jrmp.interfaces.BeanProxy.isIdentical(BeanProxy.java:130)
      at org.jboss.ejb.plugins.jrmp.interfaces.EntityProxy.invoke(EntityProxy.java:128)

      I am sure that one of my EJB's is throwing an exception that I am not seeing. I had assumed that exceptions would be thrown to the JBoss console (Windows 2000) or to the server.log file. I am not seeing an exception thrown from my EJBs anwhere though I am confident they are. Where should I be looking for EJB exceptions to be thrown?
      Or do I need to setup loggin somehow?

      Thanks
