Yeh that was just a dodgy hack to get around my initial errors when using javac. I found out later the reason why javac wasn't working on my servlet class was because servlet-api.jar wasn't on the classpath, after adding that I was able to compile it the normal way. Also the solution is NOT to put it in the WEB-INF folder, you need to have your .class file in the build/classes/<Yourpackage> folder.
