How do I return a java.util.Properties object through the rpcrouter servlet?

[MILLER,MARK M (HP-Corvallis,ex1)]

Hello,
 
I'm having trouble finding an example of a SOAP client that calls a method
on the server with returns a Properties object. The method is being called
(I'm reading the print lines in the log file) but I'm not getting any data
back.
 
Regards,
