What's your goal?  For your JSPs to use class files/jars that you've
written?  Since it's probably something specific to your web application /
Context, you'll want it in under your docBase/WEB-INF/classes directory.

Actually, it's explained here in much more detail:

By "run .jar's" I assume you mean "have access to".  If it's a jar you've
built, toss it in your docBase/WEB-INF/classes directory.  If it's a
third-party jar, like a JDBC driver, toss it in docBase/WEB-INF/lib.  That's
it.  Tomcat will load it for you when you reference it.

Example: I have a class - com.blah.blah.Loggah.  In a JSP that's in this
Context under docBase in my classes directory. In my JSP, I use:

<%@ page import="com.blah.*" %>

Then later on in the page:

<% Logger.logInfo("blah") %>

...and that's it.  You don't have to tell Tomcat anything to get it to use
your classes.  See the above link for more info as to what all is happening

All good things, doing the bull dance.

Hope this helps!
