The simplest thing to do is to add this to your program:

import java.util.logging.*;

that should turn off all messages except errors from all packages under ucar.

you might also want to investigate using logging for your own program. We 
actually use a logging facade called slf4j, so people can use various loggers 
with nj22. jdk1.4 is the default logging package (log4j is another, recommended 
for server applications).

John,

To be honest, I have no idea if I have logging enabled or not.

It's certainly not something I have deliberately specified, and in fact
I just had to Google on "jdk1.4 logging" to find out what you were
referring to.

If jdk1.4 logging is something that needs to be deliberately invoked,  then
I would assume it is _not_ on, but my cluelessness on the topic is such
that I could be wrong.

now that i look at this closer, i see that the message is going through our logging facade. are you using jdk1.4 logging? If so, you can turn off the message there.

John,
I switched my Panoply app over to use the new NJ-2.2.16 last night
and since then it has been firing off a warning message whenever
it opens a dataset. Specifically, I am getting:
  Jun 8, 2006 9:03:18 PM ucar.nc2.NetcdfFile <clinit>

WARNING: Cant load class: java.lang.ClassNotFoundException: ucar.bufr.BufrInput

In order to keep the application download time small, I have avoided
linking extra libraries into Panoply unless they are necessary, to
the functionality. I can make the above error go away by simply  linking
in the "bufr.jar" file which has appeared in the latest NJ-2.2  distro,
but I'm wondering what is in that jar that I might actually need? I
haven't yet encountered any actual error that seems to arise from
not including it, so for the moment the warning is only irritating.
