Question

I’m new to server-side development and have been experimenting with the Play framework recently. And I’m curious to know if there is an equivalent of ServletContextListener in Play. I found an Application class and a Plugin class from the Javadocs.

I want to start a bluetooth server from my web application when it starts and want to shut it down when the web app quits.

Many thanks in advance.

Answer 1

Take a look at the Global object: start your bluetooth server to the onStart() method, and stop it in the onStop() method.

public class Global extends GlobalSettings {

  @Override
  public void onStart(Application app) {
    Logger.info("Application has started");
  }  

  @Override
  public void onStop(Application app) {
    Logger.info("Application shutdown...");
  }  

}

This Global class must be located in the root of your app folder.
