Threading in an Application Server

Question

I have a Java program/thread that I want to deploy into an Application Server (GlassFish). The thread should run as a \"service\" that starts when the Application Server starts

Answer 1

Create a servlet whose init method starts a thread which is the main program.

public void init() throws ServletException {
    mailThread = new MailSendThread();
    mailThread.start();
}

In our application's web.xml file add a servlet that includes a load-on-startup element where the number is the order in which it starts.

    Mail Sending Servlet
    MailServlet
