Context: Trying to create an ANT build script that will package the application into a WAR file.

I have searched for a good while on what the problem maybe, but I cannot find anything that fits this situation.

Answer 1

I found the problem. I went through and double checked the libraries I was using, and missed the tiles-request-servlet-1.0.6.jar when adding it to the project.
