You can put your initialization code in a ServletContextListener so it
is executed before any servlets are run.

Thank you so much for the response. The reason I am doing this is , because
, I am using the servlet to start the Active MQ Broker. There are two web
apps which will connect to the broker. The broker has to start first before
any of the web apps. Hence I want to load the servlet which starts the
broker, before any of the webapps get initialized.
is there any other way I can make sure that the broker will start before any
of the web apps .
Iam using tomcat 5.5.20 and Java 1.5
