Web Service Shell

In the xx-service.cfg file you can have a line like:

singletonClassName=edu.iris.fooservice.BarSingleton

It would be useful to add the ability to call a named "destroy" method on that singleton on service shutdown.

That could be done by adding an optional line:
singletonClassShutdownMethod=destructor

In the singleton, you would see

public class BarSingelton {

     public void destructor() {
        // do cleanup here like stop worker threads etc
     }

}

The WSS would have something like the following code somewhere in it:

Method destroyMethod = singleton.getClass().getMethod(destroyMethodName);
destroyMethod.invoke(singleton);
