Re: Multiple RPC from same page gives Error 500

Hi George,
The 500 error is explicitly set from the Google code (for unexepcted
failure scenario). The code doesnt pass the RemoteServiceServlet to
reach the application code. Before itself, the payload (output of the
method readContentasUtf8) is empty. Due to this GWT is throwing the
exception.

The point Im trying to find is where the request is getting modified
on its way before reaching the RemoteServiceServlet. BTW, there are
filters in place, which is the SpringSecurityFilter

Thanks
Viju
