I am new to Jetspeed. I am trying to write my own Portlets in Jetspeed-1.
The following is a sample portlet from a book (FirstPortlet.java). The code
compiles and I copied the class file to WEB-INF/classes/local_portlets/
directory.

I added the portlet entry (see bellow) to the local-portlets.xreg file in
the WEB-INF/conf directory. I can see the new portlet in the Jetspeed admin
webpage, I can add it to the page but when I preview the page nothing shows
up :-( 

What am I doing wrong. Please help

Thanks,
Ravi

You are using parent="IFramePortlet" in your xreg definition. This is wrong as it tells Jetspeed that your
portlet definition is just a customization of IFramePortlet and thus Jetspeed will use the IFramePortlet
class and not yours.

You need to use type="base" and remove the parent defintion in the above registry fragment.
