Take a look at:
http://tapestry.formos.com/cgi-bin/viewvc.cgi/chenillekit/branches/1.0/chenillekit-tapestry/src/main/java/org/chenillekit/tapestry/core/factories/URIAssetFactory.java?view=markup
for an example of how to create custom Assets. But note that the
approach there still requires you to implement a custom dispatcher to
handle the custom-asset request.
This is generally reasonable, since only you will know how to retrieve
the asset specified by the incoming url.
The benefit to going the asset route is that you still have
opportunities for asset localization, and your assets will "snap"
right into the rest of the framework.

Hi,
I am trying to register a custom Asset type, but I seem to have
confused
myself... I'm hoping somebody more intelligent than me (not
hard :-)) can
help me out.
My problem is that I don't see how to get the client urls generated
by the
Assets I return from my AssetFactory to get correctly interpretted
by the
AssetDispatcher/AssetResourceLocator. It seems as though there is a
hardcoded assumption that the Asset is either a servlet context
resource or
on the classpath, whereas I expected the AssetResourceLocator would
somehow
determine the type of the asset based on the url and retrieve the
resource
by calling getRootResource() on the approrpiate AssetFactory and then
passing in the relative path to this resource supplied by the url.
Judging by the documention:
(http://tapestry.apache.org/tapestry5.1/guide/assets.html) it's
possible to
create assets which are, for example, stored in a database, so I'm
sure I'm
missing something obvious here.
Hope someone can help.
Cheers
Dave
