The code to initialize Cocoon, is in the Cocoon servlet's init() method. The
properties file is loaded, then the engine is initialized (the engine is
initialized via a call to Engine.getInstance(Configurations confs, Object

What you probably want to do, is instruct your servlet engine (JServ, JRun,
Servlet Exec, etc.) to load the Cocoon servlet when your web server

In JServ, go to the file you're using for Cocoon, look for:

# Startup Servlets

and add something like this:


In Servlet Exec, go to the Configure Servlets area of the admin tool, look
at your entry for Cocoon, and simply add a number in the "Load Order" field,
click submit, then restart your web server.

This is all I have. I hope it helps.
