Some queries to figure out your exact problem:

1. Are you able to access the tomcat server using the URL: http://localhost:8080/
Here I am assuming that you aer running tomcat on the 8080 port (set by default). If you can see the tomcat home page that means tomcat is running fine and there is some problem with an application that you have deployed.

If step#1 fails, try step #2

2. Have you deployed any applications in Tomcat? If so, can you try removing all the applications you have added and then try restarting tomcat? Try step #1 now and let me know the result.
