The action class (classes derived from org.apache.turbine.modules.Action) comes from the turbine framework. If you check out the turbine site (jakarta.apache.org/turbine and click on "Specification" under Essentials, there is enough to give you the general idea. Basically, by setting an action in the url /action/"actionclassname", you cause the turbine servlet to set the RunData object to use that action before the screen is run (inside the page). You can also, modify the RunData object inside of your action to change the flow of the app.
A good example of using forms,actions,and screens/portlets is the login scenario. Somewhere in your TurbineResources.prpoperties are screen.login and action.login properties. The screen.login class will set up the form that submits to the action.login class. If login is successful, it will the action will set the screen to some screen (by default, screen.homepage). If you get a good handle on that process, you should understand how it all works. For the submitting or dealing with a single portlet part, take a look at the org.apache.jetspeed.modules.screens.Home class.

Many thanks for the response! I'll try this out asap. Btw, I've heard action class a lot in this list, but I'm not sure what it is, can you give me a short description or point me to some documentation?
