Forms, portlets, and JSPs

[Andy Benjamin]

After seeing a couple threads on the subject I decided I would formalize the issue. It sounds as though I am not the only one who can't get a jsp portlet to behave as expected when dealing with forms. Simply put, all I want to do is have a jsp in a portlet that has a form. There are a few requirements:

-When I click on the submit button I shouldn't post everything back to the server, only the information in my portlet, or at least the only thing that should fire on the server is something that I want.

-The portal should only display a change in that particular pane that it is displayed in. If 5 portlets are on a page and one of them is mine, then only mine should show any change of state if I interact with it by pressing the submit button.

While getting this to work between a servlet and jsps outside of the portal is a breeze, I haven't for the life of me got this to work inside jetspeed.

Specifically I have the following questions

-What is the action of a form in the included JSP? (Scott Weaver was nice enough to suggest $jslink.template, but I assume that is some kind of velocity paradigm and didn't work for me, resulting in a 404 error.)

-Are action classes the tool to use to process the input parameters posted to the server (as if you use the jsp portlet you can't get at the jsp portlet code)? I assume that the action class would model that of a servlet outside of jetspeed.

To register an action class with jetspeed, if I have a class called called com.mycompany.portal.actions.MyActionClass with a method called "doNext()", would I put

module.properties=com.mycompany.portal

in the TurbineResources.properties file

and then in the portlet's xreg file put

<parameter name="action" value="actions.MyActionClass" hidden="false" cachedOnName="true" cachedOnValue="true"/>

And in the jsp, for the button would I put

<input type="submit" name="eventSubmit_doNext" value="Next >>">

And then for the form's action I would put what?

If someone can assist and can get me a working example I would be more than happy to make a doc of exactly how to do this so that we don't have to keep posting the same question to the newsgroup. Thanks in advance.
