Answer 1

you could use the common JSP/JSTL taglibs

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

<c:choose>
        <c:when test="${condition}">
            something
        </c:when>
        <c:otherwise>
            something else
        </c:otherwise>
    </c:choose>

alternatively

<c:if test="${condition}">
        something
    </c:if>

using c:if there is no else condition as far as i know

Answer 2

The JSTL:

<c:if test="${!empty someForm.someProperty}">

</c:if>

Answer 3

Plain old JSTL to your rescue!

The beauty of Spring MVC is that it doesn't add tons of redundant tag libraries unlike other frameworks. You can always rely on JSTL for such checks which is part of the JSP spec now.

<c:if test="${not empty someList}">

</c:if>
