Is anyone using Tomcat4.0 Beta 3 and JBoss 2.2.1? I am having a problem getting an InitialContext and get the following error: javax.naming.CommunicationException[Root exeption is java.rmi.ServerException: RemoteException occured in server thread; nested exception is java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is java.net.MalformedURL exception: unknown protocol: jndi I can get an InitialContext with Tomcat 3.2 but Catalina produces and error. I assume it has something to do with the naming services that Catalina provides conflicting with the naming services that JBoss provides. I have tried running Catalina with the -nonaming option, but this produces the same error.
