Here are three API design docs to address some common issues with the GWT RPC system.
An API for passing an authentication token or session information within RPC payloads, without having to add additional parameters to each method or playing around with HTTP headers: http://code.google.com/p/google-web-toolkit/wiki/RpcAuth How to address the problem where not all server-side Lists can be returned to the client: http://code.google.com/p/google-web-toolkit/wiki/RpcByInterface This document is more about how we might revamp the RPC payload format to improve deserialization speed, eliminate recursive behavior, and provide a well-supported mechanism for custom serialization: http://code.google.com/p/google-web-toolkit/wiki/RpcDirectEval -- Bob Vawter Google Web Toolkit Team --~--~---------~--~----~------------~-------~--~----~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~----------~----~----~----~------~----~------~--~---
