Bug 64419 Tomcat example does not need "web app root" attribute
The Tomcat/JSP launching example currently requires the user specify a "web app root" on the main tab. However, all we need is the project (in order to compute a classpath for extra java files and source lookup path). We used to require the attribute for source lookup.
