Thank you for your quick response.

i assume you are using ncCore.jar?
No. I'm using netcdf-2.2.10.jar. The download page says it just reads
netcdf 3 files but I needed to write them, too. And I am interested
(eventually) in netcdf 4.
It appears I introduced a dependency on NetcdfFileCache that i forgot
to include in the jar.
But NetcdfFileCache.class (and some inner classes) are in
netcdf-2.2.10.jar ...
This isnt a problem if you use the full netcdf.jar. If you need the
smaller jar, i will fix the problem.
It's sounds like I'm using the "right" jar. So which jar should I use?
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.

I am trying to switch from Netcdf-java 2.1 to Netcdf-java 2.2.10.
I have gotten everything switched over (grumble, grumble, a little
documentation about how to handle things that have changed would be
nice... although maybe I just didn't find it, :-) ), except for
NCdump.print and its variants. Whenever I call it, I get the error
message:
Exception in thread "main" java.lang.NoClassDefFoundError
at ucar.nc2.NCdump.print(NCdump.java:191)
at ucar.nc2.NCdump.printHeader(NCdump.java:54)
at <my code>
Line 191 in the source code you distribute is
NetcdfFileCache.release(nc);
Usually, these problems are solvable. But this time, I am at a loss
as to how to solve the problem.
It isn't an "import" problem in my code or a -cp problem on my
compiler command line, because my code compiles correctly.
It isn't a -cp problem on the java command line, because my running
code clearly finds NCdump.
It isn't that NetcdfFileCache.class isn't in the .jar you distribute
(I checked; it's there).
I looked at the list of changes for 2.2.11, but didn't see anything
that looked relevant.
I didn't find any unit test methods in the source code which would
demonstrate this class working correctly. (Maybe they are there and I
didn't find them.)
Any suggestions?
