Jersey is a project for implementing REST services, but would probably be overkill for your situation. You could simply write a servlet with a doGet method if you are handling any marshaling yourself. The Jersey project allows you to expose methods to specific URLs and any marshaling/unmarshaling is handled under the covers by these things called providers. It is intended to be used with JAXB to write an XSD from which you generate POJOs with JAXB and Jersey serializes them to XML, but custom providers can also serialize to JSON or you can write custom message body writers for your own protocol. For the simple case you are talking about I would just write a class that extends HttpServlet and overrides the doGet method and writes to the response directly.
