Very cool.
Thanks, I take a look at Velocity. > I doubt that it would be difficult to use a custom tag or JSTL > expression to fire a helper as the page was rendering.

Right, conceptually I prefer to navigate to action since action represents a web resource to me, and JSP is just a view, and I can have several views for an action. But the benefit of navigating directly to JSP is to be able to include it in another JSP, and this would work with currently available servlet engines. Including actions that forward to JSP does not work in Tomcat, for example. It is possible to dispatch to one or another page from within JSP, therefore offloading portion of dispatching functionality to JSP. Does not look nice conceptually, but works with servlet engines if I want to embed a JSP fragment into another JSP page. I think I can write a generic JSP view helper which would instantiate action class and a form bean, initialize them, call execute() on action, and then choose a proper JSP fragment to include. I will need to read config info from struts-config, I have it all in the memory, so it should be simple.
