As you may not the Felix Launchpad Web Application, is in effect just a
single Servlet, the SlingServlet. This is default to handle all requests
and does the following:
* init(): Launches The Felix framework and installs all Sling
Bundles into the framework (if launching the first time)
* service(): Forwards to the SlingMainServlet, which is part
of the Sling Engine bundle and which then uses the rest
of Sling to select a script/servlet to handle the request
* destroy(): Shuts down the Felix framework
So to integrate this into your web application, you just add the
SlingServlet (and its accompanying classes) and register the servlet in
the web application.
It may be possible to register the SlingServlet (and its required other
parts) into a Spring MVC. But we didn't test this (yet).
If you happen to succeed in this, we would be very gratefull for
documentation on the steps you did to achieve this !
Regards
Felix
