I use the NOT EMPTY to do the testing. I have
<%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c" %>
at the top of my JSP file.
But, I got an Internal Server Error 500 problem (The
log is shown after my code snippet.) I am unable to
see the problem with my <c:when ....> tag.
<c:set var="logRows" value="${requestScope.LogData}"
/>
<c:choose>
<c:when test="${NOT EMPTY logRows}">
.....
</c:when>
<c:otherwise>
<td colspan="7" align="center" bgcolor="#f5f5f5">No
Failed Log-in So Far.</td>
</c:otherwise>
</c:choose>
