Weblogic EJB Lookup fails from JBoss AS ---------------------------------------- Key: AS7-5088 URL: https://issues.jboss.org/browse/AS7-5088 Project: Application Server 7 Issue Type: Bug Environment: JBoss AS 7.1.0.Final EJB Deployed in Weblogic 10 OS - Windows XP JDK - jdk160_05 (Used by jboss) Reporter: Badal Pradhan I am trying to access EJB deployed in Weblogic 10 by its RemoteInterface from JBoss. My initial context config for lookup is as below: Hashtable<String,String> wlContextEnv = new Hashtable<String,String>(); wlContextEnv.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory"); wlContextEnv.put(Context.PROVIDER_URL, "t3://localhost:7001"); wlInitialContext = new InitialContext(wlContextEnv); During access the bean it throws the below exception: java.lang.LinkageError: Failed to link weblogic/corba/client/cluster/ORBSocketFactory ..... Caused by: java.lang.ClassNotFoundException: com.sun.corba.se.spi.legacy.connection.ORBSocketFactory Since the above class belongs to jdk rt.jar then what is the issue here? Am I missed any config for it. Note: I have wlclient.jar in my ear/lib.
