Hi PeterJ, I have gone through the docs u have mentioned in the other posts regd deployment of an application...I have an EAR file web application, which is based on MVC architecture, and i want to deploy it on JBOSS portal 2.4.0 ... Can you throw some light on the portlet.xml file, for e.g. tags like <portlet-class>....also what all .jar files are to be added in the lib folder so as to deploy the .war on portal...if the portlet instance is not created in portlets link of the management portal after deployment of war, wat shud be the 1st thing to check so as to solve the issue...
