I have installed One Java Web Application via Plesk 11.0.4 on my server. Now I want My domain name to point my web Application. My address 'www.domain.com' shows blank page. As I installed my Application via plesk , I can Access it on 'www.domain.com:9080/webapp' address. But I want to access my web application from my domain name Like www.domain.com will access my application. My webapp application's root path is : '/usr/share/tomcat6/work/Catalina/PSA/webapp'
This goes for Plesk 11.x: On the page where you can choose the web app, the 'install' button actually has a pulldown menu to its right. There you can choose 'custom install' and install into document root.
