Re: How to create Utilities method allow serizalization and deserialization request payload and response payload.

In theory what you're describing is possible with just the RemoteService interface, the corresponding <hashname>.gwt.rpc policy file, and each of the classes referenced by that policy file - the com.google.gwt.user.client.rpc.impl.AbstractSerializationStream type hierarchy should have the pieces you would need to achieve this.

In practice though, there is some JSNI required, or at least using the embedded rhino library to deal with some of the specifics, and there are no built in utilities to make this easy to do. Can you elaborate on what you're trying to achieve with this - there might be a simpler way to just help populate some simple requests and read some responses, without either a server or client process running.

There are also a few non-Java implementations out there that could help (again, for simple payloads).

I forked GWT-RPC some years ago and rewrote it without reflection or generators - one of my other main goals was to allow arbitrary other clients, and to make the wire format fully symmetrical. It has endpoints for android/jvm clients, websocket clients, and webworker clients. It cannot do 100% of what the original GWT-RPC can do, but it is in use in production and has been for some years, targeting this specific subset of functionality. I'm not sure if changing your RPC implementation is possible, but if it is, consider https://github.com/Vertispan/gwt-rpc/. There are also closed-source c++ and c# clients - obviously I cannot share that code, but I mention it to make the point that this fork is intended to be much friendlier to alternative implementations.

I read very much document, very much tutorial, but I cannot do it.

My task is: serialize request and deserialize response body without starting a server, without starting UI. I act as client.

All I have is some .jar file

Please, I would appreciate any help.
