Hi All,

javax.naming.CommunicationException. Root exception is weblogic.socket.UnrecoverableConnectException: [Login failed: 'Incompatible version:Incompatible versions - this server: client:5.1.0]
at weblogic.socket.Login.checkLoginSuccess(

I used getInitialContext method as follows :-
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
p.put(Context.PROVIDER_URL, "t3://localhost:8001");
return new javax.naming.InitialContext(p);
Any body have idea about it >>

Hi Sethu,
TX. Yes, I have both web logic version but using different port: For weblogic5.1 � port 7001 and Weblogic6.1- Port 8001.
Whenever I tried to access same Entity Bean or other bean(Session) through jsp/Servlet , it�s working perfectly. This Problem is coming with java client only (simple java standalone class) whenever tried to access.

Make sure your client classpath is using the weblogic.jar for the same version as the server.
So if your client is trying to talk to a 6.x server, have the 6.1 version of weblogic.jar in classpath.
It looks like your client classpath has a 5.1 weblogic.jar in classpath and is trying to communicate with a 6.1 version server.
I agree. Here's the link:
