help needed change the portal context to point to portal

[ramesa]

hi,
I wish to change the portal context to point to portal/myportal. I am using the menu portlet when i define my pages it is point to http://localhost:8080/portal?index.html like that instead it should point
http://localhost:8080/portal/myportal?page.portletname.pagename . i also changed in jboss-web.xml the context-root to portal/myportal. How can i achieve this one .

Regards,
Ramesa
