Just because NetBeans lets you create a portlet does not mean that you can run it. Unless you have JBoss Portal installed, which is a portlet container, your portlet will not run. Also, if you are new to web application development, I recommend that you use a simple text editor to edit all files, both source and configuration, and use the command line to build and deploy the WAR file. At this point I do not know if the problem is with NetBeans or with JBoss AS, and because I don't use NetBeans I cannot tell you what buttons to push to get it to work. Unless you are willing to do things manually, I will not be able to help you (though someone with NetBeans experience is welcome to speak up).
