The same as with the server:

java
 -Dorg.omg.CORBA.ORBClass=org.openorb.CORBA.ORB
 -Dorg.omg.CORBA.ORBSingletonClass=org.openorb.CORBA.ORBSingleton
 javaclient.ClientSub

The magic is done smart in

xmlBlaster/src/java/org/xmlBlaster/client/protocol/corba/CorbaConnection.java:118

so we don't need to manipulate this nasty orb.properties.

But still, the XML stuff or 'encode code' stuff does not work
(same problem as with the server)
I have to investigate this.

Don't know yet (see above).

But just use XML-RPC (or RMI) with xmlBlaster and switch off
the CORBA Callback plugin in xmlBlaster.properties (for your
xmlBlaster client code) - and off you go like a rocket to heaven ...

Hmm, i just try to figure out your architecture:

 --------- OpenOrb ----------  XmlRpc  ------------ Any Protocol
 | dbXML |<------->| server |<-------->|xmlBlaster|<------------>
 ---------         ----------          ------------

With 'Any Protocol' i mean any xmlBlaster supported protocol

which is currently CORBA/RMI/XML-RPC, partly EMAIL and Mr.Kakoulis
is working on a SOAP plugin.
(further protocols are implemented easily with xmlBlaster)

Please keep us informed about your progress,

Marcel
