Direct Known Subclasses:

AbstractArchiveAction

public abstract class DynaAction
extends Action

This class represent the dynamic version of the basic Action class allowing a single class to define multiple actions. Each declared method respecting the PARAMETERS signature and returning a String or an ActionMapping will be available as an action mapping in Struts. As an example both the following methods can be used in the struts configuration file as valid mappings.

• public String myMethod (ActionForm form, HttpServletRequest request, HttpServletResponse response, ActionMapping mapping) throws Exception
• public ActionMapping myOtherMethod (ActionForm form, HttpServletRequest request, HttpServletResponse response, ActionMapping mapping) throws Exception

In addition this class supports the same features providen by the org.apache.struts.actions.LookupDispatchAction but to distinguish between direct method naming and reverse lookup naming you have to prefix the reverse lookup mapping parameter with @ (at) character.
