Java provided ORB

[AMUL]

ORB.class type query

I have a java client which works with Visibrokers ORB. I am trying to get
it to work with the Java ORB provided with JDK1.3.

some client code......
*****
Properties props = new Properties();
props.put("org.omg.CORBA.ORBInitialHost", "154.222.245.45");

org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(args,props);
System.out.println ("orb is " + orb);

String[] objList = orb.list_initial_services();
System.out.println ("objList: " + objList[0]);
*****

When I compile/run my java client with visibrokers vbjc/vbj I get this:

orb is com.visigenic.vbroker.orb.ORB@653108
objList: URLNamingResolver
objList: ChainClientUntypedObjectWrapperFactory
objList: ChainBindInterceptor
objList: HandlerRegistry
objList: ChainServerInterceptorFactory
objList: ChainClientInterceptorFactory
objList: ChainServerUntypedObjectWrapperFactory


When I use the Java javac/java I get this:

orb is com.sun.corba.se.internal.iiop.ORB@25ab41
org.omg.CORBA.COMM_FAILURE: minor code: 1398079490 completed: No

Anyone got a reason why this might be happening?
Anyone using Suns ORB successfully?

Thanks.
