[Kandarp Desai]

Hi,

I'm having Following Error with RPC call.( I have read the solution
and threads switching it to GWT 1.5)
I'm using GWT 1.6.4 for Mac. It works fine When I run it on Local
Machine(mac OSX).
But, When I deployed it as WAR file to Linux Machine running Tomcat,
It gave me this error.
Can someone please help me? Thanks in advance.
