Please, help me. I have downloaded both versions of jEdit 4.1 and jEdit 4.2pre11, but can't install it.

I have installed this Java version:

e:\windows\system32\java.exe -showversion
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)



Errors for jEdit 4.1:

F:\Temp>e:\windows\system32\java.exe -jar jedit41install.jar

Exception in thread "main" java.lang.Error: can't load javax.swing.plaf.metal.MetalLookAndFeel

at javax.swing.JFrame.frameInit(Unknown Source)
at javax.swing.JFrame.(Unknown Source)
at installer.SwingInstall.(Unknown Source)
at installer.Install.main(Unknown Source)

Here the execution stops and whait for the input. When I press Ctrl-Break, it print the big dump.

How can I install jEdit? I'm the newbie in Java and I don't know how to work with it.
