Question

I need to implement a switch case using JSTL choose statement, I have tree different choise.
Anyone knows the reason why the code below doesn’t work?

Thanks in advance.

<c:choose>
    <c:when test="${iUserInfo.identification_card_type}==0">
        <option selected="selected">Carta di Identità</option>
        <option>Passaporto</option>
        <option>Patente di Guida</option>
    </c:when>
    <c:when test="${iUserInfo.identification_card_type}==1">
        <option>Carta di Identità</option>
        <option selected="selected">Passaporto</option>
        <option>Patente di Guida</option>
    </c:when>
    <c:when test="${iUserInfo.identification_card_type}==2">
        <option>Carta di Identità</option>
        <option>Passaporto</option>
        <option selected="selected">Patente di Guida</option>
    </c:when>
    <c:otherwise>
        <option>Scegli...</option>
        <option>Carta di Identità</option>
        <option>Passaporto</option>
        <option>Patente di Guida</option>
    </c:otherwise>
</c:choose>

Because you didn’t evaluate the entire expression inside ${}. Fix it accordingly:

<c:when test="${iUserInfo.identification_card_type == 0}">
...
<c:when test="${iUserInfo.identification_card_type == 1}">
...
<c:when test="${iUserInfo.identification_card_type == 2}">
