unable to launch the application

[Hussein Baghdadi]

Hi ranchers.
I want to use the jgoodies l&f inside my jar (my executable jar file).
inside the main class I wrote :
UIManager.put("ClassLoader", MainManager.class.getClassLoader( ));
try {
UIManager.setLookAndFeel("com.jgoodies.plaf.plastic.PlasticXPLookAndFeel");
}
now, I have the following tree inside my jar :
META-INF\
images\*.gif
com\*.class
plastic.jar // jgoodies jar
forms.jar // jgoodies jar
when writing :
java -jar MyApp.jar it works fine and every thing is ok (the application is uses the jgoodies l&F) but when double clicking on the jar, it doesn't launch.
(I have set the main class attribute inside the manifest file).
so, any ideas , any help please ??

If it works with java -jar it should also work by double-clicking on it. What OS & version of Java are you using?

I'm using Win2K, and my JAR files are associated with some command like this -

"C:\Program Files\Java\j2re1.5.0\bin\javaw.exe" -jar "%1" %*

I was able to find this by going into explorer, tools menu, folder options, file types tab, select JAR, press 'Advanced' button, select 'open', press 'Edit' button.
