I think that you are confused, JSTL is not needed in order to use EL:
http://java.sun.com/products/jsp/jstl/
http://java.sun.com/products/jsp/syntax/2.0/syntaxref207.html#1010522
On the other side, in the JSP 2.1 specification the JSTL has been
aligned with EL.
To use EL in your JSP pages, you must to use the JSP 2.0 specification:
http://jcp.org/en/jsr/detail?id=152
Example of a web.xml JSP 2.0 compliant:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";
version="2.4">
<display-name>...</display-name>
...
</web-app>
