Tomcat 6 is loading context twice

C

christopher

Greetings!

I edited the ContextListener.java file in a single webapp (class
files, no war) to launch a singleton and make a small addition to the
logs like this:

public void contextInitialized(ServletContextEvent event) {

this.context = event.getServletContext();
Updater.getInstance().launchThread();
log("mysite contextInitialized()"); //
<< added "mysite" only to this webapp
}

I shut down tomcat, removed the stdout.log (used to be catalina.log)
and restarted tomcat to get a 'pristine' log.

You can clearly see two "INFO: ContextListener: mysite
contextInitialized()", two singletons, two threads, etc.

What would cause this behavior?

Thanx!

there are some spurious <host> tags added my my isp (damn them!) and
one had a context path, of that matters.

All I did to fix this was copy the server.xml.sample file to
server.xml. Something bizarre my isp did in their tomcat config
caused this issue.

Thanx anyway!
