otherwise
This tag is related to the choose and when tags. It must be a child of the choose tag, and have a sibling when tag. If the when tag evaluates to false, then the content of the otherwise tag is invoked and executed (represents the “else” of if/else logic).
Syntax
<c:choose>
<c:when test="CONDITION">
<!-- processed when CONDITION evaluates to true -->
</c:when>
<c:otherwise>
<!-- processed when CONDITION evaluates to false -->
</c:otherwise>
</c:choose>
Example
<c:choose>
<c:when test="${group == null || group.elementCount==0}">
<!-- do when group named "group" is empty -->
</c:when>
<c:otherwise>
<!-- do when group contains elements -->
</c:otherwise>
</c:choose>
