I am trying to lookup a EJB deployed in Weblogic from JBoss MDB. It fails with the following error. Could not communicate with any host [ Root Exception is org.omg.CORBA.INITIALIZE vmcid: 0x0 code : 0] I have placed wlclient.jar in the root of the MDB's jar. I am using JBoss AS 4.2.2 running on JDK 1.5 and the wlclient.jar is taken from Weblogic 9.1 distribution. Please help.
