Good Morning Michael--
If I understand your question correctly the expression needs to be enclosed in
${} as in this example from Ted Husted
- <c:choose>
- <c:when test="${not empty jcookie}">
- <%-- The functionality of "logic:match" will eventually be available
- through a string function in the EL
expression. --%>
- <logic-el:match expr="${jcookie}" value="0">
- match
- </logic-el:match>
- <logic-el:notMatch expr="${jcookie}" value="0">
- notMatch
- </logic-el:notMatch>
- </c:when>
- <c:otherwise>
- missing
- </c:otherwise>
- </c:choose>
