Referencing jars from JSP helper classes

Hello:

I'm using NetBeans to develop a JSP-based web application. I'm not really too up on Ant so I'm not too sure about the building environment, etc. and I think that's the root of my problem. Anyway, here's the question...

I'm creating some helper classes (with beans style conventions for get/set) that are working fine but they only use java.lang and java.util classes up to this point. I would like to use a third party jar file in one of them, but the "import" fails because it seems the jar file can't be found. I'm not sure where to put the jar file in the project so that it can be seen at compile time! Heeeelllppp!!

Thanks...

Since this is more a build/IDE config question, I'm going to move this along to the IDEs forum.
