Start and stop a context without Manager?

Hello,

A while back this thread was posted here and it works great on my local 
dev box (using a background thread) using vhost="localhost/".  When I 
deploy it as a war the vhost name changes.

 From the output:

Attributes for object: Catalina:j2eeType=Servlet,WebModule=//localhost/##914-develop,name=MyServlet,J2EEApplication=none,J2EEServer=none:

How do I reliably get the vhost / WebModule name when using a war?

The attribute "org.apache.catalina.webappVersion" gives "914-develop" 
but its missing the ##

My war is called: ROOT##914-develop.war

Thanks
