Java.rmi.RemoteException: CORBA TRANSIENT 0x49421071 - WPS portlet - EJB Jonas

Question

Hello,
I'd like to use EJB session working in Jonas 4.3.4 (jdk 1.4) with a portlet in WPS 5.0 (jdk 1.3) throught iiop protol.
I succeed to initialized the context, then to lookup the jndiName of the EJB but when I try to instanciate (eJBhome.create()) the EJB the following exception occur :
java.rmi.RemoteException: CORBA TRANSIENT 0x49421071 No; nested exception is:
org.omg.CORBA.TRANSIENT: GETCONNECTIONKEY_RETURNED_FALSE minor code: 1229066353 completed: No
Does someone know the meaning of that corba exception ?
Does someone already succeed to do such communication ?
Do you know an other protocol that can help me ?
Here is my code in the WPS portlet:
     Properties env = new Properties();
     env.put("java.naming.factory.initial","com.sun.jndi.cosnaming.CNCtxFactory");
     env.put("java.naming.provider.url","iiop://XX.XXX.X.XX:YYYY");
     javax.naming.InitialContext initContext = new javax.naming.InitialContext(env);
     String JNDIName = "BestPracticeServiceHome";
          Object obj = initContext.lookup(JNDIName);
          BestPracticeServiceHome myHome = (BestPracticeServiceHome)PortableRemoteObject.narrow(obj,BestPracticeServiceHome.class);
     //Here occur the exception :
          BestPracticeService myService = myHome.create();
Note: if I use the WPS 5.0 test environment in RAD 6 everything works.
Thanks in advance,
Best Regards,
J�r�me

Sorry, I forgot to say, the original SunONE 7 works fine
without this error.
