extremecomponents组件使用
异常代码如下：TableTag Problem: javax.servlet.jsp.JspException: TableTag.doAfterBody() Problem: java.lang.Exception: You need to specify the totalRows (as an Integer) to use the org.extremecomponents.table.callback.LimitCallback.

页面的内容为：
<ec:table
    items="resultList"
    var="item"
retrieveRowsCallback="org.extremecomponents.table.callback.LimitCallback"
action="http://localhost:8080/public/buy.action"
imagePath="${pageContext.request.contextPath}/themes/default/images/table/*.gif"
width="100%"
rowsDisplayed="10"
showStatusBar="false"
styleClass="eXtremeTable_info"
filterable="false"
sortable="false">
<ec:row highlightRow="true">
  <ec:column property="requiresubject" title="求购名"/>
  <ec:column property="buycontent" title="要求"/>
  <ec:column property="money" title="价格"/>
        <ec:column property="buytime" title="求购日期"/>
    </ec:row>
</ec:table>
怎么回事，我的数据库里有数据啊，各位帮帮忙
[解决办法]
我是这么用的：
jsp:
<div align="center">
<ec:table items="resultList" var="item" retrieveRowsCallback="limit"
filterRowsCallback="limit" sortRowsCallback="limit"
action="${pageContext.request.contextPath}/jsp/vibrationphone/vibrationPhoneAction.do?method=list"
title="查询结果" showStatusBar="true" sortable="false">

<ec:row highlightRow="true">
<ec:column property="vibrationPhone" title="电话号码" styleClass="centercol" />
<ec:column property="vibrationType" title="类型" styleClass="centercol" />
<ec:column property="serNum" title="轮振顺序" styleClass="centercol" />
<ec:column property="name" title="操作" styleClass="centercol"><a href="javascript:update(${item.id})">修改</a>    <a href="javascript:if(confirm('确定要删除吗？')){del('${item.id}')}">删除</a></ec:column>
</ec:row>
</ec:table>
</div>

action.do

public ActionForward list(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
VibrationPhoneForm vibrationPhoneForm = (VibrationPhoneForm) form;
try {
String subscriberId=vibrationPhoneForm.getSubscriberId();
List list=getLogicDaoServiceInter().findVibrationPhone(subscriberId);
String dc = request.getParameter("ec_p");

if (dc == null
[解决办法]
dc.equals(""))
dc = "1";
vibrationPhoneForm.setCurrPageNum(dc);

/**
*
* 首先需要创建一个Limit
*/

String tableId = "";

Context context = new HttpServletRequestContext(request);

LimitFactory limitFactory = new TableLimitFactory(context, tableId);

Limit limit = new TableLimit(limitFactory);

/**
*
* 得到系统默认的页面显示大小
*/

Preferences preferences = new TableProperties();

preferences.init(null, TableModelUtils
.getPreferencesLocation(context));

/**
*
* 注意：此处取值时，如果后台配置文件里有配置，就从里面取，反之取15
*/

String pageSize = request.getParameter("ec_rd");
int defaultRowsDisplayed = Integer.parseInt(preferences
.getPreference(PreferencesConstants.TABLE_ROWS_DISPLAYED));

if (pageSize != null && !pageSize.equals(""))
defaultRowsDisplayed = Integer.parseInt(pageSize);

vibrationPhoneForm.setPageSize(String.valueOf(defaultRowsDisplayed));

int totalRows = list.size();

limit.setRowAttributes(totalRows, defaultRowsDisplayed);
request.setAttribute("totalRows", new Integer(totalRows));
request.setAttribute("resultList", list);

} catch (Exception e) {
System.out.println("查询失败" + e.getMessage());
e.printStackTrace();
this.addMessage(request, "查询失败= "+e.getMessage());
}

return mapping.findForward("list");
}
