Hi Phil, Maybe my response was specific to a situation I had before. In some of the apps I've worked on, I needed to use my own RequestProcessor to insert some logic before a <forward> is processed. If I have <action>s that don't need an Action object, using forward="myJsp.jsp" won't trigger the processForwardConfig(), in which case my overridden RequestProcessor method doesn't get called. With ForwardAction, I wouldn't have to create a do-nothing action just to forward to a JSP and ensure that processForwardConfig() still gets called. In other apps where I didn't need the custom processForwardConfig(), I still use ForwardAction so in case I do need it in the future, I won't have to go back and remap everything. Who knows, maybe the next Struts version will behave differently when all it has is forward="myJsp.jsp", though that part's just me guessing. Like I said, it depends on your app, so it may or may not affect you. Also, check ForwardAction's javadoc for another example of its use.
