Problem: I'm using Eclipse Oxygen.2 (4.7.2) on Windows 10 with Java 8. I have a faceted project I run inside Eclipse using Tomcat. I had been using Tomcat 8.5, but on a new system I upgraded to Tomcat 9. Of course I removed the Tomcat 8.5 server and server ... what it was. What do I do? Where does the problem lie? I opened Eclipse Bug 530844 to see if I can get some reasons for this behavior.

Several ports (8005, 8080, 8009) required by tomcat server at localhost are already in use
Problem: I'm getting the following error when I try to run a simple JSP program on Tomcat in Eclipse. Several ports (8005, 8080, 8009) required by Tomcat v6.0 Server at localhost are already in use. The server may already be running in another process, or a system process ... server you will need to stop the other process or change the port number(s). How is this caused and how can I solve it?
