Problem in tracing the exception of RequstFactory Application

[saurabh saurabh]

Hi all,
I have a application kind of a DynatableRf , it is using
RequestFactory and Editor API. When I call for a method like find()
or something like that on a RequestContext, this call gets back to
DAO object on server and it tries to send back the result but in
between something happens here and exceptions are thrown. Seeing the
StackTrace of exception, I am not able find out whats gone wrong in
there. Through debugging and Logging I saw there parts of my code till
server is working properly.

I guess 'Caused by: java.lang.RuntimeException: Server Error: null'
could be clue

I am really tired of this. Any idea how can I trace or resolve it.
Thanks in advance.
