Icons and Images question

[Werner Fletcher]

Hope I'm in the right section,

Just want to know why my Frames and menuItem imageicons do not work when I put it in a jar file? Running the app outside of the jar, icons etc works fine.
Any help would be appreciated!

If that's not it, post a SSCCE that demonstrates your problem.

As another step I would also check that the image file is actually within the Jar.

I remember once having the same issue as yourself and I realised I forgot to include the file extension within my ant build file.

Hey guys, thanks for the info, really appreciate it. One issue I have now... here is the code:

URL imgURL = getClass().getResource("img//titlebar2.gif");
this.setIconImage(new ImageIcon(imgURL).getImage());

This works fine when I run it via a batch file, but when everything is in a .jar file, the program does not start up at all... I verified that all the images and classes are in the right place.

Again, if that's not it post a SSCCE. Also post the internal structure of the associated jar file.

You need to tell us exactly how you attempted to run the program.

I had a look at the link you gave me. I am sure that I did it right. The jar runs fine when I take the

URL imgURL = getClass().getResource("img//titlebar2.gif");   
this.setIconImage(new ImageIcon(imgURL).getImage());

code out. As I said, the app runs fine with the above code when I run it via command line, but not in jar. I have attached images of the jar contents aswell as the app directory and contents of the manifest file. The code I use to compile my jar file is: jar cvfm NetChatClient.jar manifest.txt *.class img/*.*

OH MY WORD guys, I found the problem. I'm sorry for this whole discussion, I feel like such an idiot now. The problem was that I used dir//file instead of dir/file in my URLs. Sorry again... Please close this thread, thanks.
