Hi Joe, I think you want an Application Listener. This is a class
that implements javax.servlet.ServletContextListener which a servlet
engine (such as Tomcat) is supposed to notify on application startup.
For example:
public class ApplicationListener implements ServletContextListener
{
...
public void contextInitialized(ServletContextEvent sce) {}
public void contextDestroyed(ServletContextEvent sce) {}
...
}
You'd put your log4j/etc initialization in contextInitialized().
You'll also need to add to your web.xml file:
<listener>
<listener-class>com.foo.bar.ApplicationListener</listener-class>
</listener>
This informs the servlet engine (Tomcat) which listener class to use.
There is also a listener for session events should you need it
(implement javax.servlet.http.HttpSessionListener somewhere and add
another <listener> section in web.xml). The listeners should work in
all servlet engines (Tomcat, Jetty, etc).
mrg
