You can use a servlet init() method.
Something like
public class myservlet extends HttpServlet {
public void init() throws ...{
...put code here
}
}
then on web.xml you can tell tomcat to start that servlet when
the application is loaded. Something like what there is for the
org.apache.turbine.Turbine servlet, but add a parameter.
<load-on-startup>50</load-on-startup>
This number (50) has to do with when the servlet is loaded.
The only thing I dont know is if you have to wait for something else
before starting your job.
