Re: [Tapestry-developer] Externalizing Assets

[hl...@attbi.com]

You negelected to say what failed.

Tapestry isn't doing any magic.

You have to set up your servlet container to vend out the specified directory 
as the specified URL.

All Tapestry does is copy files to the directory, and create a URL for the 
copied file, based on the values you provide.

Take a look at the run-tutorial target in build.xml (in the distro).
You can see it creating the private directory, and specifying the 
configuration (the two system properties) there.

Look at config/jetty.xml; you can see in there that it defines the necessary 
stuff to vend out the files stored in the private directory.
