Hi
I have searched through "Enterprise Technologies - Java Technology & XML"
forum [
http://forum.java.sun.com/forum.jspa?forumID=34] using keywords I
could think of, but have not been able to see a thread discussing this
problem.
Can you please provide me some keywords that I can use to find the thread
in the forum?
Thanks
Shailender
