You should use netcdf-2.2.10.jar, which as you say has the NetcdfFileCache in 
it. so why arent you seeing it?
usually these things are classpath problems. put netcdf-2.2.10.jar first to see 
if that solves it. If it does, track down what other jar file in your classpath 
is interfering.

if not, its probably a class loader problem. but lets not go there yet.

BTW, sorry for the lack of documentation on transitioning from 2.1 -> 2.2. Ive 
gotten so used to it, I forget what has to be done.
