Hi Paul,
Sorry for this discrepancy in the log, but I just copied the error from
when i moved the HelloWorldResource into the same package as the
GrizzlyServer class (in either case, the correct package was being
specified in the init params). I just triple checked again to verify,
same problem.
The problem still persists... works fine when launched by Eclipse, but
fails with the following error if run from its own jar (either exporting
only my classes into a jar and setting up the classpath with all
dependencies, or exporting into a fat jar with all dependencies... same
thing).
