Question

I have a simple maven web project. I simply can’t figure out a way to have the JSTL tags work.
For testing purposes, I’ve created a dummy project having no dependency except for:

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
        <version>1.2</version>
        <type>jar</type>
        <scope>compile</scope>
    </dependency>

in my JSP page, I have the following test code –

<c:set var="hello" value="see this?"/>
<c:out value="${hello}"></c:out>
<h2>${hello}</h2>
<br/>
<%=request.getAttribute("hello") %>

I have also included the jstl declaration on the top –
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

However, this does not seem to work. Surprisingly, the ${hello} doesn’t show anything meaningful, but the request.getAttribute... does. This means that the c:set is actually working, and both the c:out and simple expression do NOT work. Am I missing out something here?

Any help is appreciated – been trying to get my head around this for 3 days now!

The solution lies in checking out the info document on JSTL provided within StackOverflow. It mentions almost everything there is to know about why your JSTL installation may not be working properly.
