How to use SGWTEE_HOME?

I am using smart gwt 2.0.3 on windows xp.

I have set a classpath variable named SGWTEE_HOME in my Eclipse 3.4, which is pointing to the all folder. (In which all the jar files resides)

Now to add jar files I have done: right click on the my application -> properties ->Java build path then I click on add jar and try to add jar file from memory location.

Now I just want to ask: how can I point 开发者_运维问答to my SGWTEE_HOME to add jar to my application??
