So you've followed all the instructions on installing Tomcat and you're almost ready to create your first JSP web app. Unfortunately, you can't seem to access the web interface for Tomcat even though it's started and Netbeans throws this error:
Starting of Tomcat failed, the server port 8080 is already in use.
See the server log for details.
The truth is, it may not be anything to do with the port number assigned to Tomcat!
