Opening a Document from Composite Application (Java)?

I’m searching for a way to open a notes document from a Java composite application.

Currently im using Program.launch(“notes://…”) from Eclipse. But i don’t get access to document, to send parameters.

I think the TopologyHandler or the PropertyBroker are a potential ways.

My goal are very simple:

Click on a button in a Eclipse Composite and open a Document and parse Parameters like wiring. I’dont want to use Notes Environment Variables.

Thanks for help
