Return Jersey exceptions in JSON
Depends on what you want to return, but personally I have an ErrorInfo object that looks something like this: public class ErrorInfo { final transient String developerMessage; final transient String userMessage; // Getters/setters/initializer } which I pass around as part of my Exceptions, then I just use Jackson's ObjectMapper to create a JSON string from the ErrorInfo object in the ExceptionMapp

How to embed Jetty and Jersey into my Java application
So I'm trying to embed jetty into my web application so that if I package it as a jar someone can just run the jar file without having to worry about configuring a server. However, I'm having some probl ems setting up my main class so that jetty can access my resource classes. I've looked at tutorials but they haven't given me exactly what I'm looking for. This is what I have so far. package pojo;
