can not find icon : java.lang.NullPointerException

[okxx]

Hi all,

I have a problem with icons.
Part of code :

	private JButton getJButton() {
		if (jButton == null) {
			jButton = new JButton();
			jButton.setPreferredSize(new Dimension(16, 16));
			jButton.setFont(new Font("Dialog", Font.BOLD, 8));
			jButton.setIcon(new ImageIcon(getClass().getResource("/com/img/cls.jpg"))); //---> This part fails
			jButton.setHorizontalAlignment(SwingConstants.CENTER);
			jButton.setHorizontalTextPosition(SwingConstants.CENTER);
			jButton.setText("");
			jButton.setOpaque(true);	
			jButton.setVisible(false);			
			jButton.addMouseListener(new java.awt.event.MouseAdapter() {   
				public void mouseExited(java.awt.event.MouseEvent e) {    
					jButton.setVisible(false);
				}
				public void mouseEntered(java.awt.event.MouseEvent e) {
					jButton.setVisible(true);					
				}
			});
			
		}
		return jButton;
	}

Tool : Eclipse
Source Folder : src
Package : com.img

When i run or debug this code from eclipse it works, no problem.
When i make runnable jar with this code, jar works, no problem.
When i make .exe with this code using WinRun4j with export type= Standart option(jars are out of .exe, in a folder), .exe works, no problem.
But when i make .exe with this code using WinRun4j and export type= Fat Executable option(jars and all files in .exe)it fails, can not find icons and .jrxml files.

Icons are in com.img package in src source folder, but getClass().getResource("/com/img/cls.jpg") returns null??

Whats the wrong or what can i do to solve this, anybody help ?

I would say to ask the developers/producers of WinRun4j

[Fubarable]

Is the icon image path a valid resource path? Is the image present in the Jar file here: "/com/img/cls.jpg" (relative to the current class, that is).

yess, icons and path valid, it already works by runnable jar or standart exe(jars out of exe) methods. It fails only when you create exe with fat executable method(jars in exe).

Hi all again,

I ve solved problem with diffrent method. I think this problem about WinRun4j plugin.

Anyway i found a porgram names Jar2Exe. It creates exe with no problem, no banner, makes a clear exe.

Thanks all reply

I think this problem about WinRun4j plugin.

Didn't I essentially say just that a few posts ago? Did you bother even trying to find a mailing list or forum or some other support/comment/bug link at the "homepage" for that library?
