interop problems with iiop between sun and ibm jvm's

I'm trying to connect a java gui (that will be launched with webstart - on a sun jvm) to a websphere server which is hosting an EJB.

It works if I launch my java gui with a ibm jvm. But if I use a sun jvm, I get this:

The code I am executing to do this is:
Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
ht.put(Context.PROVIDER_URL, "iiop:localhost");

InitialContext ctx = new InitialContext(ht);

Object homeRef = (ITS_SessionFacadeHome) ctx.lookup("ITS_SessionFacadeHome");

Is there a fix for this?

"vortex vortex",

We're pleased to have you here with us in the WebSphere forum, but there are a few rules that need to be followed, and one is that proper names are required. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

It's not a secret anymore!
