Your WARs are deployed in the JBoss instance's deploy directory. You will probably run the JBoss default instance so put your WAR in server/default/deploy of the JBoss distribution. JBoss does not expand the WAR.
That should get you started.
Thank you.But I want to know more details to more than getting started.
I am not sure how to organise my jsp's, servlets & other web stuff in jboss.
Can u help ? Please
You need a lot more information than a forum can/should provide. For a JSP/Servlet configuration, a JSP book was a great resource for me. Many of the JSP books use JSPs with Servlets in their examples.
Once you feel more comfortable with the JSP/Servlet, use JBoss to activate them (which information is in the getting started guide).
