Thinking a bit more about this (read trying out some stuff). The way we want to change the API is right now is ‘just’ the message format, how about we take a servlet filter that changes the json from the old version to the new?

There is a lib [1] that takes a json and transforms it into another json.

Other option is to have 2 jax-rs classes, but to make that work they will have to have 2 different paths. So you would have to ‘redirect’ / change the path in the servlet filter based on the accept header. Which feels like kinda of a hack to me.

So WDYT any other suggestions?

Cheers,

Erik Jan
