For some reason, webstart doesn't always clear out the old cached
idvbase.jnlp classes.  So it still points to the old nc2.2.jar instead
of ncIdv.jar.

You'll need to clear out IDV from your Web Start cache.  You can 
do this by opening:

http://www.unidata.ucar.edu/software/idv/webstart/IDV/player.jnlp

finding the IDV entry and deleting it.
