Re: trouble with servelts

You are missing the servlet.jar file, which contains the neccesary classes for your servlet to compile.
Just make sure your compiler can find the jar file in your classpath. If you have a IDE like netbeans
than you have it easy, just mount the jar file, and you will be able to compile without problems.
