Directory structure while developing/deploying
WebApplication using  Tapestry. Please Help.

I was looking at the examples ( say hello ).
All the files related to this examples say
.application, .page, .html and .java files are stored
under WEB-INF/classe/<package> directory. 
what I wanted to know is, Is this a directory
structure we should maintain throught out application
or ist here any way to organise directory /files on
our own. I want to structure something like shown
below

|-docroot
| |-images -- All images file
| |-invoice- htmls will go here+.application, +.page
| |-reports--All html,*.page
| |-InvDocs-- htmls ........so on
|-WEB-INF
    |-classes - <package>-*.class
