How do I do the equivalent of a java If-Else block using JSTL? [duplicate]

Answer 1

<c:if test=${var1 == var2)}>
</c:if>

There is no Else is JSTL you have to do multiple If's (Sucks I know)

Must add this at top

<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>

Answer 2

You can use <c:choose> for this. The equalsIgnoreCase() can be done by lowercasing the both sides by fn:toLowerCase().

<c:choose>
    <c:when test="${fn:toLowerCase(var1) == fn:toLowerCase(var2)}">
        Both are equal.
    </c:when>
    <c:otherwise>
        Both are not equal.
    </c:otherwise>
</c:choose>

Or when you're targeting a Servlet 3.0 container (Tomcat 7, Glassfish 3, JBoss AS 6, etc) with a web.xml declared conform Servlet 3.0, then you can invoke the equalsIgnoreCase() method.

<c:choose>
    <c:when test="${var1.equalsIgnoreCase(var2)}">
        Both are equal.
    </c:when>
    <c:otherwise>
        Both are not equal.
    </c:otherwise>
</c:choose>
