This will happen if you are using only a JRE and not a JDK. I've also occasionaly seen it when using a JDK and also with tools.jar on the classpath which is a strange one. As it says if you copy tools.jar from the JDK to the common/lib directory of your tomcat install it will definitely solve the problem.

I really dont'know why just this application gives me this kind of error. The problem seems to be that the jsp pages aren't compiled but why?
