You can override ProxyCreator and provide your own super class for your RPC services (by default RPC services extends RemoteServiceProxy). This allows you to override doInvoke method and put additional data into payload.
In our project (acris-security) we add session ID into the payload in this way so you can inspire by the code: - SessionEnabledRemoteServiceProxy - overriding doInvoke method - http://code.google.com/p/acris/source/browse/trunk/acris-security/src/main/java/sk/seges/acris/security/client/session/SessionEnabledRemoteServiceProxy.java - SessionProxyCreator - overriding RPC service proxy creator- http://code.google.com/p/acris/source/browse/trunk/acris-security/src/main/java/com/google/gwt/user/rebind/rpc/SessionProxyCreator.java - SessionRemoteServiceProxyGenerator - overrinding GWT generator - http://code.google.com/p/acris/source/browse/trunk/acris-security/src/main/java/sk/seges/acris/security/rebind/SessionRemoteServiceProxyGenerator.java and finally, enable generator on all RemoteService interfaces <generate-with class="sk.seges.acris.security.rebind.SessionRemoteServiceProxyGenerator"> <when-type-assignable class="com.google.gwt.user.client.rpc.RemoteService" /> </generate-with> or you can enable this generator only for specific service interfaces.
