Events, outgoing interfaces?

Hello, I am new to this list.
I try to use my own COM objects from within Java code and I found Jawin. I think it is great piece of software.
 
What I need is to hook on some events (my COM objects are something like the middle tier between applications and Message Queuing). 
Are there some equivalents to DispEventAdvise and DispEventUnadvise (C++) in Jawin?
 
I have generated stubs for my COM objects and now I want to implement the callback class with outgoing interface.
Unfortunately I have found no clue neither in this mailing list nor in documentation or demos.
 
Please can anyone help me?
Thank you in advance...
