Perhaps you can register a LifecycleListener for your tomcat application (link). A lifecycle listener will be called when your context is loaded and right after it is being closed.

Here is a more involved explanation link. You might want to look at the contextInitialized and contextDestroyed methods of the ServletContextListener interface.

If you are doing a normal restart you should be able to register a shutdownhook and have it run before the server kills the app.

Check out the javadocs for more detailed info: http://docs.oracle.com/javase/6/docs/api/java/lang/Runtime.html#addShutdownHook(java.lang.Thread).

You can add a shutdown hook like this:

Runtime.getRuntime().addShutdownHook(new Thread(new Runnable(){
    public void run() {
         // clean-up logic
    }
}));
