Introduction

The JavaServer Pages Standard Tag Library (JSTL) allows you to use functional tags which simplify  programming in JSP’s. This example shows how it’s done with a simple test for a condition

<%-- Declare the core library --%>
<%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c" %>

<%-- Simple  conditions --%>
<c: test='${param.p == "someValue"}'>
    Generate this template text  p equals someValue
</c:>

<c: test='${param.p}'>
    Generate this template text  p equals "true"
</c:>
