portlet tutorial

[xgj6688]

Where can I get a portlet tutorial which will teach me how to design a JSR-168 portlet step by step?
Must I use IDE such as webshpere studio or Sun IDE?
Can I just use JDK tools such as javac, jar or ant to desin a simple portlet? Is there any portlet plugin for eclipse?
I have download jBoss AS+jBoss portal, it does work, but I want to design my own 'hello word' portlet and deploy it on jBoss portal. Please help me. Thanks in advance.

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
Thanks
