Hi Sekhar, You have some framework like piriti (http://code.google.com/p/piriti/) for JSON serialization of data. It can be a good start. However, it does not use overlays: it copy JSON values to POJO fields.
Maybe you can be interested in my code: http://code.google.com/p/tyco/source/browse/?repo=tikray The idea is to define interfaces for data. A generator automatically create implementation for GWT with zero-overhead (no field copy, just wrappers arround JSON value that will be removed by the GWT optimizer). This part starts to work with (many) limitations. The second part is to create some Java proxy to use the same mechanisms on server. I'm owrking on. Maybe this code can help you.
