handling parameters passed through the url path
Suppose I want to pass a parameter like this:
http://somedomain.com/JohnSmith
instead of http://somedomain.com?username=JohnSmith
so the parameter looks like a subdirectory.
Can a tapestry page plus some kind of service hande this?

Actually, you can have as much parameters as you want:
onActivate(EventContext context). This will handle any number of
parameters, all them accessed through the context parameter.

This is a common error. Never use relative URLs. Use absolute URLs or,
better yet, use the context binding prefix. Example below.

<img src="${context:/path/to/file.extension}"/>. This will work in all
pages and components, no matter the folder your page is (their URL).

So, I can pick up the /UserName in my index page and forwards to the required page, although of course that will limit me to only handling 1 parameter linked to 1 page.
I am also finding that resources such as this in my layout.tml
<img src="layout/images/page_bg.png" border="0" width="960" height="799" alt="" style="position:absolute;left:0px;top:149px;"/>
cannot be located when I request pages with params in the url. Is there some way to reference the root context in my layout paths?

The Index page is the root page.

If you'll need more stuff like that in your app, having a single page
handling all them will be a mess.

That's the page activation context:
http://tapestry.apache.org/page-navigation.html, specially section "Page
Activation".
Basically, on a page class:
void onActivate(String username) {
// username will get the first parameter in the URL (slash separated)
}

Easy, I would go as far as to say that this is the preferred way in
Tapestry. See:
http://tapestry.apache.org/page-navigation.html
for examples of onActivate() and onPassivare().
