jre problems.

Every time I go to start any program up, I get this error.

[democrab@archlinux ~]$ java ~/mcpatcher-1.1.11.jar
Exception in thread "main" java.lang.NoClassDefFoundError: /home/democrab/mcpatcher-1/1/11/jar
Caused by: java.lang.ClassNotFoundException: .home.democrab.mcpatcher-1.1.11.jar

Could not find the main class: /home/democrab/mcpatcher-1.1.11.jar.  Program will exit.

I got it on Minecraft (Minecraft and some support apps like the above are the only reason I use java) but I fixed that by geting it from the AUR instead, how would I fix this? I've tried reinstalling (And redownloading), I'm on 64bit.

Re: jre problems.

You can't launch a jar file directly. As per the man page, you need to use the -jar flag to java.

Ahh...I thought that was a Windows only thing, oh well, thanks.
