Hi,

you're right, the class My5250 uses a few System.exit() calls.

This is a little source snippet, which you may use to bootstrap 5250j
yourself ... this way you're avoiding to use My5250j and it's exit() call=
s.

-----------------------------------------------------------
import java.awt.BorderLayout;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.io.File;
import java.util.Properties;

import javax.swing.JFrame;
import javax.swing.JPanel;

import org.tn5250j.Session5250;
import org.tn5250j.SessionBean;
import org.tn5250j.SessionConfig;
import org.tn5250j.SessionGUI;
import org.tn5250j.interfaces.ConfigureFactory;


public class ExampleEmbeddedMinimalBootstrap {

	public static void main(String[] args) {

		try {
			System.setProperty("emulator.settingsDirectory",
File.createTempFile("tn5250j", "settings").getAbsolutePath());
			ConfigureFactory.getInstance();
			org.tn5250j.tools.LangTool.init();
			final SessionBean sb =3D createSessionbean();
		=09
			JFrame frame =3D new JFrame("TN5250j");
			frame.setSize(1024, 768);
			frame.addWindowListener(
					new WindowAdapter() {
						public void windowClosing(WindowEvent e) {
							sb.signoff();
							sb.disconnect();
						}
					}
			);
		=09
			SessionGUI sessgui =3D new SessionGUI(sb.getSession());
			JPanel main =3D new JPanel(new BorderLayout());
    		main.add(sessgui,BorderLayout.CENTER);
    		frame.setContentPane(main);
			frame.setVisible(true);
			sb.connect();
		=09
		} catch(Exception e) {
			e.printStackTrace();
		}
	}

	private static SessionBean createSessionbean() throws Exception {

		String system =3D "127.0.0.1"; // TODO: your IP/hostname

		SessionBean sessionBean =3D null;
		SessionConfig config =3D new SessionConfig(system,system);
		config.setProperty("font", "Lucida Sans Typewriter Regular"); //
example config

		Session5250 session	=3D new Session5250(new
Properties(),system,system,config);

		sessionBean =3D new SessionBean(session);

		sessionBean.setHostName(system);
		sessionBean.setCodePage("Cp273");
		sessionBean.setNoSaveConfigFile();
		sessionBean.setScreenSize("27x132");
		sessionBean.setDeviceName("devname");

		return sessionBean;
	}

}
