How to deal with break in jsp
Sometimes, we have to deal with the break in a for iteration.
In jstl, there's no break logic. But we can achieve that by composing the jstl tags.
The following is an example:
Code:

for (int i=pageVariable; i<= showThisMuch;i++) {
if (j==10){
break;
}
}

Code:

<c:forEach varStatus="status" begin="${pageVariable}" end="${showThisMuch}">
     <c:if test="${j<10}">

     </c:if>
</c:forEach>

Thanks for Bruce's advice

To compare dates, try this

Code:

Date: <fmt:formatDate value="${now}" dateStyle="full" />
Number: <fmt:formatNumber value="${now.time}" />
StartDate:<fmt:formatDate value="${startDate}" dateStyle="full" />
Start Number:<fmt:formatNumber value="${startDate.time}" />
<c:set var="checkTime1"><fmt:formatNumber value="${startDate.time}" /></c:set>
<c:set var="checkTime2"><fmt:formatNumber value="${now.time}" /></c:set>
<c:if test="${checkTime1 < checkTime2}"> Start Date is Less than today's date </c:if>
<c:if test="${checkTime1 == checkTime1}"> Same dates </c:if>

In some aspects, EL expressions are different form java expressions
in java
Code:

1/3=0

in el
Code:

1/3=0.333333...

In the jsp pages we need to do the paging, somethime we need the type of int number, not the fload or double.
How to do the rounding operation?
Code:

<fmt:formatNumber value="${showThisMuch-(showThisMuch%20)}" pattern="00000.#" />
