Hi...
I am using Struts in my application. In one of my pages I am using core JSTL tag to
iterate a set of collection object (2 rows displayed per page) along
with next and previous links so that the other results could be viewed on the click of
next... The code is as follows...
<c:set var="noOfRows" value="2" />
<c:forEach var="actual" items="${loginForm.clientCollection}" begin="${param.first}"
end="${param.first + noOfRows - 1}">
<tr>
<td>
<c:out value="${actual.name}"/><br>
</td>
<td>
<c:out value="${actual.password}"/><br>
</td>
</tr>
</c:forEach>
<c:choose>
<c:when test="${param.first > 0}">
<a href="confirm.jsp?first=<c:out value="${param.first - noOfRows}"/>">Previous</a>
</c:when>
<c:otherwise> </c:otherwise>
</c:choose>
<c:choose>
<c:when test="${param.first + noOfRows < 5}">
<a href="confirm.jsp?first=<c:out value="${param.first + noOfRows}"/>">Next</a>
</c:when>
<c:otherwise> </c:otherwise>
</c:choose>
The first time when the page gets displayed the 2 rows are displayed with values and
with a 'next' link... When I click on next, I get no results -- I guess at this
moment,
the collection is empty though the param.first takes the value 2!! Is there anything I
am missing??? Kindly advice...
