Hi all- I have a web application that uses some static resources to make them available to any class in the application. Amongst these static resources is a home-brewed JDBC connection pool. What I'm seeing is that with Tomcat 4, when I stop/start or reload an application from the manager app, it isn't freeing up these static resources. I can see this because my memory utilization goes up about 5 megs every time I restart, whereas if I stop and restart the whole tomcat process, my memory stays the same. Also the database starts yelling at me about too many applications simultaneously etc.
How can I tell Tomcat to clean up these resources when it stops the application? What hook/mechanism is there? Is there some sort of listener interface I can implement, similar in idea to an HttpSessionBindingEvent, to let me know when an application is shutting down so I can close all of the database connections? None of this was an issue in Tomcat 3.x because I had no choice but to shut down the entire tomcat instance! Any help greatly appreciated! Thanks! Best regards, Richard
