MqMsgque PACKAGE - the package-main is a single piece of code evaluated only once at application startup …

Example from MyServer.java → The package-main configure the factory and start the server.

package example;

import jvmkkernel.*;
import jvmqmsgque.*;

// package-item
final class MyServer extends MqContextC implements MqServerSetupIF {

  // Factory Constructor
  public MyServer(MqContextC tmpl) {
    super(tmpl);
  }

  // service to serve all incoming requests for token "HLWO"
  class MyFirstCallback implements MqServiceIF {
    public void Callback(MqContextC ctx) {
      SendSTART();
      SendSTR(ReadSTR() + " World");
      SendRETURN();
    }
  }

  // define a service as link between the token "HLWO" and the class "MyFirstService"
  public void ServerSetup() {
    ServiceCreate("HLWO", new MyFirstCallback());
  }

  // -------------------------------------------------------------

  // package-main
  public static void main(String[] argv) {
  
    // create the "MyServer" factory… and return the initial (top) object
    MqContextC srv = MqFactoryC.Add(MyServer.class).New();

    try {
      srv.LinkCreate(argv);
      srv.ProcessEvent(MqWaitOnEventE.FOREVER);
    } catch (Throwable e) {
      srv.ErrorCatch(e);
    }
    srv.Exit();
  }
