I think with Jürgen's code corrections and the existing script provider for ooRexx I can go on with the further development on my own. If not I know where to ask :)
Thanks again,

no you didn't misunderstood the guide. _getComponentFactory is the newer
suggested way to go because it uses a component context. For creating a
new instance of a service you should use XMultiCompopnentFactory instead
of XMultiServiceFactory. But the old __getServiceFactory should work
also as well as XMultiServiceFactory. This is documented in the latest
version of the DevGuide which of course is not online until now. But i
will update it after my vacation.
But you have two errors in your code, see below ...

it should be __getServiceFactory with two underscores

a type in the string, better you use
String impl = _ScriptProvderForJava.class.geTName();
That has the advantage that it works for Java 1.5 as well because Java
has changed the class format in Java 1.5 and inner classes have changed.
Correct this twi erros and it shoudl work. I've tried to register at
least the new built jar file and it worked fine.
