问题 I have a very strange problem. I am creating a JPA (Eclipselink) application, with a Jersey rest service, and an angularJS front end. When the application starts up, when I go to my angular page, I get a marshalling exception which seems to be caused by a null pointer somewhere. Press refresh in my browser, and the data comes back - no exceptions, and I am good to go from there on in. I am using @XMLInverseReference on a one to many join, and the way I have set the annotations is the only way

Everything works fine in a test environment but we're having serious issues in the production environment due to a firewall cutting killing inactive connections. Basically if a connection is inactive for a while a firewall the sits between the Tomcat server and the DB server kill it, with the result of leaving "stale" connections in the pool. The next time that connection
