Minecraft Forums

I am so confused by this. How do I start diagnosing my server? And I have no experience whatsoever with this programming stuff. What do I put where and run?

i got this error message when adding the 1.4.4 file to my server jar. I would add the attachment but i dont know how to, there doesnt seem to be a simple button for it

Nevermind i just copied it
