Background Thread for a Tomcat servlet app [duplicate]

Answer 1

Another way if you are using spring based framework you can specify the class/thread which you want to initialize in the beans.xml. So when the tomcat starts up, beans.xml will initialize all the classes mentioned in it. You can also pass constructor arguments if required. Below is the example of the same.

beans.xml

MonitoringService.java

public class MonitoringService{

     private MyThread myThread;

     public MonitoringService(int seconds){
          myThread = new MyThread(seconds);
          myThread.start();
     }
}
