Help? "Javac" unrecognized

Well I followed the guide on Moparscape http://www.moparscape.org/smf/index.php/topic,200036.0.html
And so far it was going very well, the port forwarding wasn't as hard as i thought. It was all going good until, i got this...

So i tried doing chapter 7 to fix it and it still doesn't work,
HELP?

 

ive had same problem before i just went to java.com and downloaded JDK 5-6
and it worked for me so..

 

no wait before you do what tank said... most of the time its that you don't have your class path and path set right... go to HERE
and follow that tut then restart your pc if that dosent fix it then go to java.com and download jdk 6 hope this fixes it for you

 

This should fix it right click your compile delete all the text in there and replace it with this


@echo off
color 0a
title WOAH compiler
"C:\Program Files\Java\jdk1.6.0_05\bin\javac.exe" -cp . *.java
pause

replace

jdk1.6.0_05

with what jdk version you have to figure out what version you have got to local disk c program files
java folder it will say jdk
and then the version
