newbie: how to make IDEA to recognize jstl file?

I'm very new to intelliJ, currently I do'nt know how to make IDEA to recognize jstl file, that is : standard.jar and jstl.rar.
In eclipse or netbeans all I did is just copy it to lib folder. In IDEA although I copied like that but it not worked.
Could you describe in detail step by step?
And about tld files, in eclipse or netbeans all I did is just copy tld folder to WEB-INF folder, then in web.xml
I added below lines and they worked:
http://java.sun.com/jstl/fmt /WEB-INF/tld/fmt.tld http://java.sun.com/jstl/core /WEB-INF/tld/c.tld http://java.sun.com/jstl/sql /WEB-INF/tld/sql.tld http://java.sun.com/jstl/x /WEB-INF/tld/x.tld ]]>
But intelliJ not. Currently I'm evaluating itelliJ 8.0 M1
Please help me, I need your help.
thanks in advanced.
