[jboss-user] [Beginners Corner] - NetBeans IDE: Classpath not working for a JLabel icon image

[victorj42]

Hi all,

I get an error after using NetBeans to select an image file for a JLabel icon. 

IDE code that works: 
gallows.setIcon(new javax.swing.ImageIcon("K:\\Hangman\\images\\gallows.gif")); 

IDE code that fails when I run the project: 
gallows.setIcon(new javax.swing.ImageIcon(getClass().getResource("/gallows.gif"))); 

How I'm selecting the image location: 
1) from the IDE click the [...] next to the icon property of my label then choose classpath and click [select file]. 
2) I am able to navigate to the file correctly and it is displayed in the preview window. I can even see it when I click on the test form button. 

If I run my file I get an error: 
netbeans Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException 
        at javax.swing.ImageIcon.(ImageIcon.java:138) 
        at Keyboard.initComponents(Keyboard.java:175) 
        at Keyboard.(Keyboard.java:15) 
        <following errors removed by me> 

I hope someone can help me

Thanks
