Hallo Andreas,

Although it sounds very good, I have no idea and found no hints how to
do this. I have to fall back to your second solution. Or may be you have
some hints for me...

I did now following:
-----%<----
// Conditions:
// opened OO Document
// XMultiComponentFactory xRemoteServiceManager
XMultiServiceFactory xMultiServiceManager = (XMultiServiceFactory)
UnoRuntime.queryInterface( XMultiServiceFactory.class,
xRemoteServiceManager );
Object oProtocolHandler = xMultiServiceManager.createInstance(
"de.twc.oocom.SaveACopy" );
// get the XDispatchProvider and XInitialization interfaces
XDispatchProvider xDispatchProvider = (XDispatchProvider)
UnoRuntime.queryInterface(
XDispatchProvider.class, oProtocolHandler );
XInitialization xInitialization = (XInitialization)
UnoRuntime.queryInterface(
XInitialization.class, oProtocolHandler );
-----%<----
The Object oProtocolHandler always is null. If I understand right, I
need a class de.twc.oocom.SaveACopy. I created it and you can find it at
the end of the mail (it is nearly the same as
http://kingyo.tutms.tut.ac.jp/~toshi/StarSuite/Chap4/EX4710/).
How can I tell UNO where to find the class de.twc.oocom.SaveACopy?
Greetings, Tobias
