struts显示列表出错！大家帮帮手

Question

Cannot find bean userActionForm in scope request
说的很清楚。

Answer 1

你的ACTION中的VO传回的值要与你的JSP页面中的LOGIC中的NAME值一样，你才能正确的取到值

Answer 2

<logic:iterate id="userListAction" name="userActionForm" scope="request" type="com.jansky.weboa.entity.userActionForm">
  <tr>
    <td>&nbsp;<bean:write name="userListAction" property="user_id"/></td>
    <td>&nbsp;<bean:write name="userListAction" property="user_name"/></td>
    <td>&nbsp;<bean:write name="userListAction" property="user_pwd"/></td>
  </tr>
    </logic:iterate>改成上面的应该ok!

Answer 3

Action如下：
package com.jansky.weboa.Action;import com.jansky.weboa.entity.*;
import org.apache.struts.action.*;
import javax.servlet.http.*;
import java.sql.Connection;
import java.sql.SQLException;
import java.util.Collection;
import com.jansky.weboa.db.connPool;
import com.jansky.weboa.db.userDAO;
public class userListAction extends Action {
   private connPool pool;
  public ActionForward execute(ActionMapping actionMapping, ActionForm actionForm, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) {
   // userActionForm userActionForm = (userActionForm) actionForm;
   // throw new java.lang.UnsupportedOperationException("Method perform() not yet implemented.");
    Connection con=null;
    con = pool.connPool();
    userDAO user = new userDAO(con);
    Collection col = user.userList();
    httpServletRequest.setAttribute("userActionForm", col);
    return actionMapping.findForward("success");  }}
ActionForm如下:package com.jansky.weboa.entity;
/**
 *Title:实体建模
 *Description：定义表user中列项的属性
 *Time:2004-9-15
 *Company:jansky
 *Author:黄晓华
 *version1.0
 */
import org.apache.struts.action.*;
import javax.servlet.http.*;
import java.util.ArrayList;
public class userActionForm extends ActionForm {
  private String user_id;
  private String user_name;
  private String user_pwd; 
  public String getUser_id() {
    return user_id;
  }
  public void setUser_id(String user_id) {
    this.user_id = user_id;
  }
  public String getUser_name() {
    return user_name;
  }
  public void setUser_name(String user_name) {
    this.user_name = user_name;
  }
  public String getUser_pwd() {
    return user_pwd;
  }
  public void setUser_pwd(String user_pwd) {
    this.user_pwd = user_pwd;
  }
  public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest httpServletRequest) {
    /**@todo: finish this method, this is just the skeleton.*/
    return null;
  }
  public void reset(ActionMapping actionMapping, HttpServletRequest httpServletRequest) {
  }
}

Answer 4

Action改为：
Collection col = user.userList();
    httpServletRequest.setAttribute("userActionForm", col);
    return actionMapping.findForward("success");

Answer 5

晕，怎么就发出去了？？Action改为：
    Collection col = user.userList();
    httpServletRequest.setAttribute("list", col);
    return actionMapping.findForward("success");jsp：<logic:iterate id="userListAction" name="list" scope="request" type="com.jansky.weboa.entity.userActionForm">
  <tr>
    <td>&nbsp;<bean:write name="userListAction" property="user_id"/></td>
    <td>&nbsp;<bean:write name="userListAction" property="user_name"/></td>
    <td>&nbsp;<bean:write name="userListAction" property="user_pwd"/></td>
  </tr>
    </logic:iterate>
