Is it reaching the server side code - I mean RPC Implementation
class ?
You can see in Debug. put a break point in RPC server impl.


If not reaching there , then it is definition issue - check web.xml,
sync and async method.
Debug mode gives very good Idea.

Looking like some mismatch while dispatching to servlet impl.

Does arraylist have any elements ?

Seems like you did a yourArrayList.get(0) call on an empty ArrayList inside your getCMSData() method. So I would check that first.
