Hi,

I'm trying to connect to a WebSphere 6.1 EJB 2.1 from JBoss EAP 6.2 (AS 7.?)..

InitialContext ctx = new InitialContext(props);
Object obj = ctx.lookup(jndi);

returns :

com.sun.corba.se.impl.corba.CORBAObjectImpl extends org.omg.CORBA_2_3.portable.ObjectImpl which extends org.omg.CORBA.portable.ObjectImpl (this implements org.omg.CORBA.Object) so i don't understand the ClassCastException ! Am i missing something here ?

The exact same .war works on Glassfish 4 without problems... So i am assuming something is not correct with my JBoss.. I'm using the standalone-full.xml

JDK version : 1.7u51
