EL Variable (like, for example: ${test}) is not evaluated

[Yamir Encarnacion]

Hello,

I have the following custom tag

   
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<%@ taglib uri="http://www.springframework.org/tags" prefix="spring" %>
<%@ taglib prefix="springcst" tagdir="/WEB-INF/tags/spring_custom" %>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
 
<%@ attribute name="path" required="true" %>
<%@ attribute name="label" required="false" %>
<%@ attribute name="required" required="false" %>
<%@ attribute name="maxlength" required="false" %>
<%@ attribute name="id" required="false" %>
<%@ attribute name="onchange" required="false" %>
 
<c:set var="test" value="Page Level Value" />
${test} <c:out value="${test}" />
${path} <c:out value="${path}" />
${label} <c:out value="${label}"/>
 
<br>
<table class="fieldsTable" cellpadding="0" cellspacing="0" width="100%" border="0">
    <tr>
        <td align="right" width="20%">
            <c:choose>
                <c:when test="${not empty required || required == 'true'}">
                    <label for="${path}">
                        <springcst:required/>${label}
                    </label>
                </c:when>
                <c:otherwise>
                    <label for="${path}">
                        ${label}
                    </label>
                </c:otherwise>
            </c:choose>
        </td>
<%--        <td id="${path}" align="left" width="25%">--%>
        <td align="left" width="25%">
            <form:input path="${path}" maxlength="${maxlength}" onchange="${onchange}"/> 
        </td>
    </tr>
    <spring:hasBindErrors name="command">
        <c:if test="${not empty errors}" >
            <tr>
                <td/>
                <td class="fieldError" colspan="2">
                    <form:errors path="${path}"/>
                </td>
            </tr>
        </c:if>
    </spring:hasBindErrors>
</table>
 

I call this tag like follows:

  
<%@ taglib prefix="springcst" tagdir="/WEB-INF/tags/spring_custom" %>
<springcst:simpleInput path="USR_USERNAME" label="User:"/> 
 

However, for some reason EL variables ${test}, ${path} and ${label} are not evaluated. They print out as ${test}, ${path}, and ${label}

I would like for them to be evaluated to their respective values. How do I achieve this?

p.s. This same code was working fine in a previous application I used it in. Also, I am using Tomcat 5.5 and JSTL 1.1

Have you read through the JSP FAQ entries on this issue? Is your web app properly declared in web.xml?

Thanks Bear Bibeault. Your post guided me to the information that I needed.

Thanks again

That's what the FAQs are for! Glad they helped.
