I'm really having a hard time finding something that will work here. Regarding your suggestions:
- Json Overlay Types (This one I have not implemented yet...I was not sure how to do this) - AutoBeans I can't get this to work properly, there are no errors reported just doesn't work at runtime. When using it on the server to encode I get a null bean. When using it on the client I get what looks like a mock instance (random derived type) of the right type but it has no data. - Frameworks like Piriti (http://code.google.com/p/piriti/) This one almost worked...it generated code but because some of types I marshal are parameterized (pass data of type T)...it generated code that returned T but the class itself was not typed so java could not compile the code. Seems it just does not handle parameterized types. - maybe you can borrow you some code from resty-gwt ( http://restygwt.fusesource.org/documentation/restygwt-user-guide.html#JSON_Encoder_Decoders ) I had tried this one first...ran into a problem here too...just don't recall the details. - you can roll your own solution using GWT's generators at compile time. (Not sure how to do this either) Also...I found the gwt-streamer library it's purpose is to convert POJO to JSON and/or XML and the reverse. This seemed ideal as then I could just pass the resulting string as a single item JSON map but it didn't work because the library contains code references that are not implemented in the GWT JRE emulation library. So although it was advertised for client side GWT apps I don't see how that is possible. Any other suggestions? Know of any good Json Overlay Types examples?
