Using library inside a Jar

[Hussein Baghdadi]

Hi all.
I have developed a swing application and package it into executeable jar.
I have the following structure :
-------------------------------------
currentdir\com\*.class // dir for all class files
currentdir\images // dir for all images
currentdir\lib\kunststoff.jar // dir for kunststoff L&F
-------------------------------------
I want my application to use the kunststoff L&F, so :
how to use this L&F with my application ? and what should I put
inside the main class of my application (I know how to use UIManager.setLookAndFeel( )) and I don't mean it).
I think , I should use the class loader to access this jar, but how??
(please, you will help me very much if you give the important lines of code)
thank.

Why wouldn't you just put the jar on the classpath to access the classes?

Because when I have packeged my app in an executable jar, my application uses the default L&F and not the Kunststoff

Please forgive me if I'm being dense, but when your jar is on the classpath, can you not call UIManager.setLookAndFeel(packages.to.Kunststoff.KLookAndFeel) or some such? I have never built a custom look and feel, so maybe I just don't understand the problem.
If you have to have the ClassLoader, try getClass().getClassLoader() and use that to load the L&F class directly. If the classpath setting is insufficient to make the classes visible, try using the util.jar.JarFile to read a stream of bytes and ClassLoader.defineClass() from that.
Thanks,
Joe
