Hi Dan, Yes, well, thats ok, I only skim most posts to the list (not yours, of course ;-). And after re-reading my questions, I can see that I tend to waffle on, like I am now - doh! So, what I though was a problem is actually a feature, useful for deployed customisation, quite ingenious. In the wash, it seems the trick it to accept the way things work with request forwarding and make the most of them. If you map your "web actions" so that they appear to be in the same directory as your JSPs you can also avoid the "conceptual" problem. Thanks for your input.
