Embedded Linux Development Using Yocto Project Cookbook - Second Edition

How to do it...

We will use the following meta-custom/recipes-java/java-helloworld/java-helloworld-1.0/HelloWorldSwing.java graphical Swing hello world example:

import javax.swing.JFrame; 
import javax.swing.JLabel; 
 
public class HelloWorldSwing { 
    private static void createAndShowGUI() { 
        JFrame frame = new JFrame("Hello World!"); 
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
 
        JLabel label = new JLabel("Hello World!"); 
        frame.getContentPane().add(label); 
 
        frame.pack(); 
        frame.setVisible(true); 
    } 
 
    public static void main(String[] args) { 
        javax.swing.SwingUtilities.invokeLater(new Runnable() { 
            public void run() { 
                createAndShowGUI(); 
            } 
        }); 
    } 
} 

To integrate this HelloWorldSwing application, we can use a Yocto meta-custom/recipes-java/java-helloworld/java-helloworld_1.0.bb ...
