javax.servlet.ServletException: Cannot find bean jlist in scope request
org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:867)
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:800)

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:248)
javax.servlet.http.HttpServlet.service(HttpServlet.java:856)


2、定位问题
1）action类代码如下，且经过验证list是存在数据的
  List list = new ArrayList();
  VersionBean bean = new VersionBean();
     ServletContext app = request.getSession().getServletContext();
     String sql = (String) app.getAttribute("f_listVersion");
     try {
   list = bean.qryVersion(sql);
  } catch (SQLException e) {
   logger.error("QryVersion failed！");
   logger.error(e.getMessage());
   return mapping.findForward("fail");
  }

  request.setAttribute("jlist",list);
return mapping.findForward("success");


2）jsp显示页面，代码也正常
   <logic:present name="jlist" >
   <logic:iterate id="list" name="jlist" scope="request">
 <tr>
  <td height="46" width="82" align="center">　
  <bean:write name="list" property="verID"/>
  </td>
  <td height="46" width="138" align="center">　
  <bean:write name="list" property="name"/>
  </td>
  <td height="46" width="58" align="center">　
  <bean:write name="list" property="status"/>
  </td>
  <td height="46" width="232" align="center">
  <bean:write name="list" property="description"/>
  </td>
  <td height="46" width="50" align="center">
  <input type="radio" value="<bean:write name="list" property="verID"/>" name="verID">
　</td>
 </tr>
   </logic:iterate>
   </logic:present>



3）接下来查看struts-config.xml 配置文件，发现forward redirect属性为true，当试着修改成false的时候，重启tomcat，就查询出来结果了。

    <action
      path="/version/listVersion"
      type="com.webike.action.ListVersionAction"
      scope="request">
      <forward name="success" path="/version/list.jsp" redirect="true"/>
      <forward name="fail"    path="/version/index.html" redirect="true"/>
      </action>

Eclipse版本：wtp-all-in-one-sdk-R-1.5.3-win32.zip，同事给的一张安装光盘，雪中送炭，谢谢啊。
MyEclipse版本：MyEclipseEnterpriseWorkbenchInstaller_5.0M2_E3.2.exe，在网上下载的，百度了一个序列号就OK了

创建Struts工程步骤：
1、打开Eclipse，进入File >> New >> Project ，选择MyEclipse >> Web Project ，点击 “下一步”，输入工程名称创建工程



2、选中工程名称，点击右键属性，选择MyEclipse >> Add Struts Capabilities……，输入好信息后，点击Finish 完成



3、选中工程名称，点击右键属性，选择New >> other，在MyEclipse树形目录中可以找到web-struts，进入选择即可以编写struts了
