Logging

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

import java.util.logging.*;

Logger logger = Logger.getLogger("ucar"); 
logger.setLevel(Level.SEVERE);

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).
