Netbeans 7.4 includes Glashfish 4.0, which includes Jersey 2.0. If you use the "New Project..." and generate a REST sample project, it adds all of the Glashfish 4.0 stuff, include Jersey. It includes this in the startup:
INFO: Initiating Jersey application, version Jersey: 2.0 2013-05-03 14:50:15...
How do I remove Jersey 2.0 and add Jersey 2.3.1? There seems to be no easy way to do this in Netbeans.
