The standard JSTL tags support simple conditionals with <c:if> and complex
conditions with <c:choose>, <c:when>, and <c:otherwise>. The expert group
debated this at length and found the latter model to be better than a
syntactically odd <c:else> tag.
Usage works like this:
<c:if test="${user.iq > 150}">
You seem like a pretty smart guy.
</c:if>
And:
<c:choose>
<c:when test="${user.iq < 100}">
below average
</c:when>
<c:when test="${user.iq < 120}">
moderate
</c:when>
<c:otherwise>
intelligent
</c:otherwise>
</c:choose>
See the JSTL spec for more information; also, all JSTL books should cover
this material in detail. Hope that helps,
