Question

after a loop runs and populates a data table I want to calculate the totals of the columns and display them on the last row.

This is my code to populate the table…I need to build the last row:

<table class="data_table">
  <tr>
    <th>Source Of Issues</th>
    <th>First Issues</th>
    <th>second Issues</th>
    <th>Changes</th>
  </tr>

  <c:forEach var="bean" items="${beans}" varStatus="loopCount">
    <tr>
      <td><a href="foobar">${bean.sorCode}</a></td>
      <td class="right"><fmt:formatNumber value='${bean.firstissue}'
                             type="currency" groupingUsed='true' /></td>
      <td class="right"><fmt:formatNumber value='${bean.secondissue}'
                             type="currency" groupingUsed='true' /></td>
      <td class="right"><fmt:formatNumber value='${bean.changes}'
                             type="currency" groupingUsed='true' /></td>
    </tr>
  </c:forEach>  
</table>

Answer 1

<c:set var="sum" value="${0}"/>     
<c:forEach var="bean" items="${beans}" varStatus="loopCount">
  <c:set var="total" value="${bean.actualLabor + bean.plannedLabor}"/>
  <tr>
    <td><a href="foobar">${bean.sorCode}</a></td>
    <td class="right"><fmt:formatNumber value='${bean.firstissue}' 
                           type="currency" groupingUsed='true' /></td>
    <td class="right"><fmt:formatNumber value='${bean.secondissue}'
                           type="currency" groupingUsed='true' /></td>
    <td class="right"><fmt:formatNumber value='${changes}'
                           type="currency" groupingUsed='true' /></td>
  </tr>
  <c:set var="sum" value="${sum + changes}"/>      
</c:forEach>

<fmt:formatNumber value='${sum}' type="currency" groupingUsed='true' />
