Re: getting the name right: check the documentation and make sure you have it right!
Re: the classpath, it depends on BlueJ. I have no idea how that works. But if it's like any other IDE I've ever seen, you have some kind of "project" attribute (to your IDE or project, not to the classes you're writing) or tab or menu item, and from there you can configure the project. One of the things you can configure is the class path. The element.* classes probably are in a jar file. So the IDE probably has a way to add that jar file to the class path.
Check your documentation.
