I've had so many Java errors setting up my server. Need assistance please.

http://pastebin.com/NGAPiM63 There's the pastebin for my most recent one. The problem with this is, I may only use Java 6, because if I use Java 7, I can't connect to minecraft.net in client. So, I need someone's help. I figure if I can get at least one person to help me here, even if I have more errors I could get this server set up. My friend really loves Equivalent Exchange and a lot of servers have that stuff disabled. So, IF something crashes my server, I'm fine with that, because it'll be running.

Thanks in advance,

Shade

I believe you need Java 7 :)

I believe you need Java 7

BUT, when I use Java 7... I cannot connect to minecraft.net, 32 or 64-bit. I am running a 64-bit OS.

uninstall ALL java on ur machine an start with a fresh install of java 7 64 bit, make sure ur client pulls from the 64 instead of the 32 bit
