I have found an eclipse plugin to develop portlet at http://prdownloads.sourceforge.net/plutoeclipse/org.eclipsefan.pluto.ui_1.0.0.zip?download. But it is not for jBoss portal, I must define some xml files which are specific for jBoss. Can I find a jBoss portlet plugin? thanks.
A useful information for you xgj6688. I hope that you might have many portlets tutorials for yourself to read and work on it.
there is a site called liferay.com which uses the portlets.Go to the site www.liferay.com and see it. You can download the src as well as the binary files and try to install it. But you need jboss/tomcat/mysql and ant for it to work.
All the best
