Subject Re: Using RequestDispatcher.include() outside of Request/Response cycle.
Date Wed, 10 Oct 2007 02:34:23 GMT
Hello,
Consider using either Request / Response Wrappers subclassed and
modified so they simply return 0 / null / "" / ignore output, or google
for "servlet api mock objects" or something similar.
Ages ago I wrote something similar, where specified pages were called on
webapp start / stop. Don't ask :/
It was on Tomcat 4.0, but I believe there's nothing in the specs that
prohibit such (ab)use, so it should work with any servlet container.

Greetings, Lilianne E. Blaze
