Ok -- I'll bite -- I've finally discovered what sub-applications are all about [hint -- the documentation needs improving in this area]. It's pretty easy to see how to transition into a subapplication from the default subapplication, but I'm not sure what syntax to use in a forward to reference a non-context and non-application-relative URI.
Of course, I could always use an absolute URL, but that would mean that I would have to either hard code that into my struts-config.xml file (bad), or programmatically determine it (bad). I think there must be something I'm missing in my understanding of this useful technology for supporting modular, decoupled web application development. Can someone explain how I get out of the roach (subapp) motel? Steve
