If you check out http://sling.apache.org/site/jspc.html and scroll to the
bottom you will see a note about deployment:
The generated JSP classes as well as the Declarative Services descriptor are
automatically copied to the generated bundle jar file if the Maven Bundle
Plugin (from the Apache Felix) project is used to build the project package.

How can I put compiled jsp classes to the repository (under /var/classes)?
A bunch of curl commands? There are around 1000 jsp/class files.
I don't want to put jsp files but class files only to the repository.
Or, I don't want to have the application compile jsp on the fly.
