You should be able to refer to the code that's called when the "Export  
Archive (KAR)..." menu is clicked. Take a look in src/org/kepler/gui/ 
ExportActorArchiveAction.java

I was able to get this message too when importing a java actor of mine  
that's not yet in the kepler tree -- but only if I don't first right  
click on the actor and use the Semantic Type Annotation menu to  
annotate it before exporting it as a kar.
Kepler isn't sure where to place an actor in the tree if it's not  
semantically annotated. Try annotating your actor and then exporting it.

If you define the parameters of an actor, and then export it, these  
should be saved in the moml within the kar file, and should show up  
when you import the actor. I have just run some tests here, and it's  
working for me for regular parameters.
However! We have found a bug in the export code where this is not  
working properly for PortParameters. Are you using PortParameters in  
your actor? I've checked in a bug about this issue that we will try to  
fix.

I'm not clear on what you're asking here, can you be more specific? Is  
it that you want to have a custom configuration box that pops up when  
you click "Configure Actor"?
