Probably best to take one step at a time. Drop the include. Just do
everything in one page.

Here you import TestClass.

The full name of this class is TestClass.TestClass

Forget the JAR. If you have the class, why do you need it again?

This should be ...\classes\TestClass\TestClass.class since your class
declares it is in package TestClass.

This is wrong both ways round. The common/lib folder is for JARs used by
Tomcat, not for applications.

Again forget the JAR. Do one of two things:
1) Remove the package statement from your code and put TestClass.class in
WEB-INF/classes.
2) Put TestClass.class in WEB-INF/classes/TestClass, since that's the
package you declared it to be in.
