Unable to Run Jenkins in tomcat which already host other webapplication

Question

When I tried to deploy Jenkins.war file in Tomcat7.0.1 server I was able to deploy it without any hassle and i am able to access Jenkins with local:8080/jenkins/ URL. In the above case, I did not had any other application already deployed.

But When I tried to deploy the same Jenkins.war in another tomcat server with version 6.0 which had already running web applications did not gave any error during deployment, but i was not able to access jenkins with the URL - localhost:8080/jenkins/ and neither the application was appearing on the web console as deployed, but the exploded war was found under the tomcat folder /webapp

I searched for solutions and got some hints pertaining to port number issue but did not clearly got what need to be done.

On Single port only one application will run. So Your current tomcat is already running an application on its default port 8080.So jenkis will not run on that.

Download a new tomcat zip unpack the same,edit conf/server.xml[conf folder is inside tomcat] and change connecter port to 8081 or whatever,but port must be free.

After changing the port add jenkins war to webapps of your new tomcat and start the tomcat.Now youu can access the jenkins over 8081 port and your application as it is
