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). > > > > On Tuesday, February 23, 2016 at 4:27:16 PM UTC+5:30, Thomas Broyer wrote: > >> >> >> On Tuesday, February 23, 2016 at 11:47:25 AM UTC+1, [email protected] >> wrote: >>> >>> Hi All, >>> >>> I am upgrading GWT 2.0.3 to GWT 2.7 then I am facing a lot of problem >>> like RpcService , HybridServiceServlet and ClientOracle error. can someone >>> tell me RpcService, HybridServiceServlet and ClientOracle is not >>> available then what is available instead of that in GWT 2.7? >>> >> >> com.google.gwt.rpc (aka Direct-Eval RPC, or deRPC) was experimental (the >> javadoc used to state “EXPERIMENTAL and subject to change.
