how to write a JSP only portlet

[natbox]

Hi,
I would like to write a JSP only portlet for simplicity and ease of maintenance. I am wondering what class should put in the <porlet-class></portlet-class> in portlet.xml to make this work. I am using jboss AS 4.0.2 and jboss portal 2.0RC2. Thanks!

It shouldn't be possible to use JSP or servlets, because the starting point of a portlet application needs to implement the Portlet interface. But maybe it would be interesting to specify something like Java Portal Pages to offer some scripting possibilities.

while it is easy to script the rendering phase, how do you script the processAction ?

I didn't get that much into this ;-(
But couldn't you use/extend the portlet tag lib for actionrequests?

[julien1]

the request dispatcher is not available during the processAction

This is getting difficult for me... I tried to do some analogical reasoning between JSP (get/ post requests) and portal pages (render/ action requests). But this doesn't seem to work, because get/ post requests of a JSP are not compiled into a servlet's doGet/ doPost methods, but rather into a single _jspService method.

But wouldn't it be possible to compile a java portal page (jpp) into some Portlet type with a _jppService method? If you would mark a scriptlet in the jpp with an element which includes attributes like the method name and request type you could compile a portlet which dispatches the request to the corresponding methods.

sorry, but WTH ?

Let's start this over by asking: what is it that you try to acomplish?
You shoul duse portlets where they make sense, and JSPs where those make sense. Don't try to force fit things.
