Resteasy provides way to specify alternate content types by using file extensions using resteasy.media.type.mappings. However, once mapping is done, to call a resource having query parameter in the URI, the URI needs to be specified as
<HOST>/email@example.com (for xml)
<HOST>/firstname.lastname@example.org (for json).
This is non-intuitive. It would be better if mapping works with URI such as the one given below
