Hi, I'm sorry but on Jersey I can't help you so much ... On the server side (speaking absolutely from a personal and subjective point of view) I'd not use Node.js, but instead other (more JVM-centric) frameworks ... some week ago I discovered this (probably the most jvm-centric framework closer to node.js):
http://vertx.io/ Otherwise I'd use Grails or Play (or Lift), or Wicket on the server side ... all these should have utility classes for transformation of pojo from/to json, xml, etc ... One of the things I'd like to improve in Pivot (maybe for 2.1) is the extensibility for our existing Serializers. Ideas, comments, etc as always are welcome. Hope this helps (at least a little). Bye, Sandro
