Optimizing webservice response message

Question

I'm facing a performance issue with my web-service.

The context

I'm coding a game on Android that consumes a web service. It 's a multiplayer game so there are many connections done to the web service.

My Rest web service is provided by an Axis2 instance on a Tomcat server.

The problem

All is working fine, except that the amount of data is huge because of the verbosity of XML. I tried to optimize the exchange by never resending a data that the client already have. I use gzip compression. I think that jSon is not a solution because, it will light the response message but not as I would.

So my questions, what should I do to maximum light the response size? What are the best practices? Is it possible to send only a serialized object without using jSon or xml to avoid verbosity?

Answer 1

Thank you for all your reponses xD I think that I have to send serialized objects in a custom format but Axis2 only deals with xml stuff (Jax-WS).

So I'll try another Rest server like Jersey which deals with custom format (Jax-RS). What do you think about that?
