I do this using JSTL but I am sure there is a better way:
<c:if test="${actionBean.context.user != null}”>
// do stuff
</c:if>
You could also do this:
<c:choose>
<c:when test="${actionBean.context.user != null}”>
// do something...
</c:when>
<c:when test="${actionBean.context.user == null}”>
// do another thing…
</c:when>
<c:otherwise>
// or do something completely different.
</c:otherwise>
</c:choose>
