Hi Thomas,I want to ask one thing that ClientOracle is in deRPC and deRPC has been removed from 2.7 then instead of ClientOracle what is using in GWT 2.7 and What is the use of ClientOracle?. and in my existing application which is GWT 2.0.3, i have used two method processCall(ClientOracle clientOracle,String payload,OutputStream stream) and processCall(String payload) so, what is use of two methods in GWT 2.0.3?
Impossible to answer without knowing what you're doing with ClientOracle. A typical application would not need to directly touch a ClientOracle, which means your application added some customizations; but not knowing what those customizations are, it's impossible to tell whether they're available in "standard" GWT-RPC.

So,How can I resolve the RPC Related issue in GWT 2.7. When I migrated older version(2.0.3) to Higher version(2.7) then I am getting error like RpcService,HybridServiceServlet and ClientOracle. In my existing Project RPC has used that's why I am migrating GWT 2.7 then These errors are coming like RpcService,HybridServiceServlet and ClientOracle. So,If RPC is not there in GWT 2.7 then what is present in GWT 2.7 which resolve the Rpc related issue and also confirm me that RPC is available in GWT 2.7 or not. Please re-read my previous mail, and possibly go read the documentation at http://www.gwtproject.org/doc/latest/ DevGuideServerCommunication. html RpcService, HybridServiceServlet and ClientOracle were part of "Direct-Eval RPC" (aka deRPC), which was experimental and discouraged for use in production.deRPC has been removed in 2.7, but GWT-RPC is still there. deRPC and GWT-RPC are (were) two different things; deRPC aimed at being a "better GWT-RPC" and replacing it, but it failed, so GWT-RPC is still there and deRPC has been retired.Migrating (back) to GWT-RPC should hopefully be as easy as switching RpcService and HybridServiceServlet (and/or RpcServlet) to RemoteService and RemoteServiceServlet respectively; and remove the <inherits name="com.google.rpc.RPC"/> from your gwt.xml.You're talking about ClientOracle though, which means you possibly had some customization on top of the "out-of-the-box" deRPC, so migration *might* not be that easy (depending on the kind of customization you have).Last, but not least, there must have been a reason to use the experimental deRPC over standard GWT-RPC, so maybe switching (back) to GWT-RPC might not be the solution for your case, but it's impossible to say without more information. If you don't know the reasons for using deRPC either, I'd suggest, given how easy it should be, to move (back) to GWT-RPC and see if that works. If it doesn't work, then I'm afraid you'll have to put quite some work in either "making it work", or migrating to something else entirely (e.g. JSON-RPC, or JSON-based RESTful services).

Do not use this in production code."), and didn't fulfill its expectations, so it was removed in 2.7.0-RC1.You have to migrate to com.google.gwt.user.*.rpc ("standard" GWT-RPC), or if that was a problem (that made you use deRPC in the first place), then migrate to RequestFactory or an entirely different protocol (JSON-RPC, or some JSON-based RESTful protocol for example).--
