Yes it is. Meanwhile We've found the source of problems. We have a dispatcher servlet so that we don't need to register our services in the web.xml file. The code for this servlet was probably taken from an example that was using an old version of GWT that didn't need to pass the SerializationPolicy and SerializationPolicyProvider to the RPC methods.
Now the problem is solved. Thanks the same for your help.
