I have a java enable domain (suppose www.example.com) and I have uploaded a .war file in this domain ( suppose example.war), So the web application is executing in www.example.com/example link. Now my question is, is it possible to execute the web application in onlywww.example.com link?
In Tomcat, you can do this by replacing the default webapp in the root context with your own webapp. However, unless you also change Tomcat's port assignments, you'd still have to have the ":8084" in your URLs. And if you reassign Tomcat to port 80, most OS's will demand that Tomcat be started as a privileged user, which means that the system will be less secure.
A popular alternative is to front Tomcat with a proxy server such as Apache httpd. The proxy server can listen on port 80/443 safely (usually) as well as translating from a virtual host root to a Tomcat non-root context.
