Question

I wanted to store a character value in a variable using the JSTL

My code to do this is:

<c:set var="letter" value='${param.colorLetter.toLowerCase().charAt(0)}' ></c:set>

Next i need to try and check if the character was ‘v’:

        <c:choose>
            <c:when test="${letter}=='v'">
                <lable>Color Name: </lable>Violet<br/>
            </c:when>
        </c:choose>

Currently I feel that it is not storing it as a Character Variable and so the test is failing. (No errors/exceptions)

Answer 1

<c:set var="letter" value="${param.colorLetter.toLowerCase().charAt(0).toString()}" />

<c:choose>
    <c:when test="${letter eq 'v'}">
        <lable>Color Name: </lable>Violet<br/>
    </c:when>
</c:choose>

You have to put the whole test between ${} and to add toString() after your charAt(0) to cast from Character to String.
