I read somewhere that I can dispense with a huge CLASSPATH environment variable by plonking all my required jar files in jre\lib\ext and the runtime will automatically look for packages there. I've done that but it doesn't seem to pick it up. Can someone help me understand the relevance of jre\lib\ext and how to make it work ? Thanks. Pho
Pho, It's interesting that it doesn't work for you because it works for me - and I'm not adding jre/lib/ext to my classpath.

OK Mark, Now you made me go out and learn something . This is some reading on extension libraries: http://java.sun.com/j2se/1.3/docs/guide/extensions/spec.html and it says that one of the properties of System is the java.ext.dirs property and that it defaults to < java-home>\lib\ext [Win32] or < java-home>/lib/ext [Solaris]. So I guess that you DO NOT need to put it in your classpath. However if you put extensions anywhere but the default, then you need to modify this property.

Also bear in mind that it can be easy to get confused if you have more than one JRE or SDK installed. In particular, on Windows Systems there is usually a JRE in "Program Files" as well as one in wherever you installed your Java 2 SDk. Make sure that your jars are in the right one (or both if you are very cautious).
