I am getting this exception when I try to create a initial context to hit the weblogic server. This is the code I am trying from eclipse.I have added weblogic.jar and wlclient.jar in the classpath.

 Hashtable env = new Hashtable();
        // WebLogic Server 10.x connection details

        env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" );
        env.put(Context.PROVIDER_URL, "t3://localhost:7001");
        env.put(Context.SECURITY_PRINCIPAL, "xxxxx");
        env.put(Context.SECURITY_CREDENTIALS, "******");
        return new InitialContext( env

Has anyone faced this issue,How to resolve it?
