Hi Paul,
I don't know what it was, still can't figure that out... But depending
on the jar export settings used in Eclipse, it seemed to be causing a
problem.
I can build the classes, then jar them myself (or with ant) and have it
work, but a jar exported with Eclipse is causing the errors.
I didn't try this before because I've never had an issue with Eclipse
creating jars for me before, this was just a simple test server for a
proof of concept to test throughput of Grizzly/Jersey
It does work though... just can't jar it with Eclipse for some reason.
