Compare current date with dat from db by JSTL

Question

hi all
I use
<tr><c:forEach items="${allFound}" var="found" varStatus="myRow">
<td><c:out value="${found.submitDate}"/></td>
</tr>
</c:forEach>
to past some value out of db
how can I compare this submitDate with Current Date by JSTL
Thank you!

Whether or not you can compare it depends on what the type of "${found.submitDate} is coming from the Database.
I am going to presume it is a java.util.Date.
You can get the current date like this
<jsp:useBean id="now" class="java.util.Date"/>
You can then compare them using an EL expression:
{code}
<c:if test="${submitDate < now}">
We have not yet reached the submit date.
</c:if>{code}
EL uses the java compareTo methods, so both of your objects +must+ be of the same class in order for this comparision to work.
If you get back a String from the database, you would have to use <fmt:parseDate> to get a java date.
If you get back a java.sql.Date from the database, it would get trickier. The hack would be to go java.sql.Date -> String -> java.util.Date using <fmt:formatDate> and <fmt:parseDate>
Hope this helps,
