Hi,
you seemed to misunderstand Jenkins...Jenkins is a CI Solution which can be used for many think...I'm not sure if there is a Plugin to deploy to application servers like JBoss, Websphere, Galssfish or other things like Tomcat...
But you will not find a war plugin in Jenkins...cause usually you will create the war file using Maven deploy this file to a repository manager and from there you will deploy the war file into the appropriate application server or servlet engine etc...
Maybe you can give more details on what you like to achieve?
Kind regards
