Classes used in the web app have to be in a place where one of the involved classloaders can get at them. Usually that's WEB-INF/lib or WEB-INF/classes in the wbe app itself, or maybe in a shared directory of the servlet container, or -as a last resort- via the extension mechanism of the JVM. If none of these work, then it's either really tricky (think custom classloaders) or impossible.

Why can you just not include the class on the web app like normal?

classes that you can invoke in your Servlet must be placed in the specified directory of your webapp that is WEB-INF/classes

Not correct. That's just one of the places it can go. Ulf has already pointed out the appropriate locations.
