How to use JSTL in NetBeans

I have copied from my tomcat folder the two libraries,jstl.jar
and standard.jar and I have put them under WEB-INF/lib in my
web application in NetBeans.Which is the way to use these libraries?

this works (prints hello quest) but I think that I have to add something else in the first line...
Thanks in advance...

Before using <c:out /> tag, you should set a variable "user" with a specific value in one of the implicit objects: session, request, page ...
