Subject Re: org.omg.CORBA.MARSHAL: java.lang.ClassCastException thrown while marshaling the reply
Date Sat, 26 Nov 2005 21:12:13 GMT
Unfortunately I can't give you any advice except to trace through the  
code to try to figure out what is going wrong.  Are you fairly sure you  
have csiv2 set up on your c++ client compatible with the TSS setup you  
have specified?  I would sort of expect a different exception if this  
is the problem, but it often seems to me that the sun corba  
implementation is written with the primary goal of concealing the cause  
of problems.

Please keep us informed of your progress!

thanks
