Tomcat Server not starting with in 45 seconds

Question

Server Tomcat v7.0 Server at localhost was unable to start within 101 seconds. If the server requires more time, try increasing the timeout in the server edit

Answer 1

I had tried increasing the Server Start up time for tomcat server, removed server and created new server, removed server and changed run-time environment configurations. Those thing didn't work for me. At last, i found deployment descriptor(url pattern of servlet-mapping) is the one that making the trouble.
