how to set java home on windows 7?

Question

I set two environment variables in the ‘system’ of the control panel. I named it JAVA_HOME for both the variables which point to 

 

C:\Sun\SDK\jdk\bin

 

But I get this below error when I run it

 

BUILD FAILED

C:\Users\Derek\Desktop\eclipse\eclipse\glassfish\setup.xml:161: The following error  occurred while executing this line:

C:\Users\Derek\Desktop\eclipse\eclipse\glassfish\setup.xml:141: The following error occurred while executing this line:
