Using IIOP to remotely connect to EJB's running in a weblogic cluster does not work.
If one of the cluster nodes stops the client does not fail over to the other node but throws an exception.
javax.naming.NamingException: Unhandled exception in lookup [Root exception is org.omg.CORBA.COMM_FAILURE: Connection refused: connect vmcid: 0x0 minor code: 0 completed: No]
Caused by: java.net.ConnectException: Connection refused: connect
When using T3 as a protocol this works without exceptions.
