Tom,
How do I look at the contents of a jar file? Is there a jar file viewer
or decompiler?

Judi,
I would compare the contents of your jar files - the one that works
vs. the one that now doesn't work. i.e. jar tf workginJarFile.jar >
l1; jar tf nonWorkingJarFile.jar > l2; diff l1 l2. This might help
you see if, for whatever reason, the images didn't make it into your
current jar file.
Good luck.

I am working on an application that needs to load various images
and there seem to be a million different ways to do this in the
examples I have found online. The method I have found to work most
reliably until recently is this:
LogoLabel.setIcon(new
javax.swing.ImageIcon(getClass().getResource("Images/WF5_200.gif")));
This is part of the setting up of a JLabel within a JPanel and it
runs perfectly well within NetBeans. I thought I was doing quite
well and have managed to call other functions from JButtons in the
main app.
At various times I have built (compiled) the project to a jar file
and have tested it to see that it runs OK under the runtime
engine. So far so good. However, in recent weeks the jar file has
stopped running. It builds with no error messages but if I run it
from my desktop shortcut the cursor shows "waiting" for a couple
of seconds and then reverts to normal and nothing else happens. If
I run it from the command line within the \dist\ directory I can
see an "Unknown Source" error message followed by a pointer to the
line of code above that loads the gif file. It appears to me that
the compile/build function cannot interpret the file location. I
have tried placing a copy of the image in the same directory as
the source java file (and removing the images\ path) but still no joy.
Now here's the strange thing. Until the end of August it would
build and run OK. I was able to retrieve the previous jar file
from my backup and it still runs perfectly well.
I cannot understand what has changed and would be grateful for any
suggestions as to where I might look to solve this very
frustrating problem.
With thanks,
Judi R
