删除记录问题

页面可以这样改:

  1.   

    action处理改成这样:package com.wwtest.action;import org.apache.struts.actions.DispatchAction;

    public class kehuxinxi_search extends DispatchAction {
        public ActionForward dokehuxinxisearch(ActionMapping mapping, ActionForm form,
                                      HttpServletRequest request, HttpServletResponse response)
                throws IOException {
            TestDao td = new TestDao();
             List  users=new ArrayList();
            display_kehuxinxi mform2 = (display_kehuxinxi) form;

                 ...
             }
            
            if (weijibianma == null || weijibianma.trim().length() <= 0) {

              } catch(Exception e){
               try {
                   DBUtil.rollback();
                   DBUtil.closeConnection();
               } catch (Exception e1) {
                   e1.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
               }
               e.printStackTrace();         }
            return forward;
        }}
      

  2.   

    document.loginForm3.action="/kehuxinxi_search.do?action=delete&wjbm="+wjbm;请问上面的action="/kehuxinxi_search.do?中的kehuxinxi_search是不是在我struts-config.xml中
     
    <action path="/deletekehuxinxi" type="com.wwtest.action.kehuxinxi_delete"   
      name="loginForm3" parameter="method" scope="request">
     <forward name="delete_sb" path="/delete_sb.jsp" />
     <forward name="delete_cg" path="/delete_cg.jsp" />
     </action>的deletekehuxinxi
      

  3.   


    错误提示:
    type Status reportmessage /deletekehuxinxi.dodescription The requested resource (/deletekehuxinxi.do) is not available.IE框内空为:http://localhost:8080/deletekehuxinxi.do?%20action=delete&wjbm=88888888
      

  4.   

    把document.loginForm3.action="/deletekehuxinxi.do?action=delete&wjbm="+wjbm;
    中的/去掉试试
    还有问号后边不能有空格
      

  5.   

    提示:
    type Exception reportmessage description The server encountered an internal error () that prevented it from fulfilling this request.exception javax.servlet.ServletException: Request[/deletekehuxinxi] does not contain handler parameter named 'method'.  This may be caused by whitespace in the label text.

  6.   

    这是我现在的action
    public class kehuxinxi_delete extends DispatchAction {
        public ActionForward dodeletet(ActionMapping mapping, ActionForm form,
                                      HttpServletRequest request, HttpServletResponse response)
                throws IOException {
            TestDao td = new TestDao();        ActionForward forward = null;        String action=request.getParameter("action");
            System.out.println("action:  "+action);
            if("delete".equals(action)){
                 String wjbm=request.getParameter("wjbm");
                 System.out.println("wjbm:  "+wjbm);           if (wjbm == null || wjbm.trim().length() <= 0) {
                   request.setAttribute("errMessage", "用户名不能为空");
                   return mapping.findForward("delete_sb");
                  }            try{
                 td.delete_kehuxinxi(wjbm);
                  DBUtil.commit();
                  return mapping.findForward("delete_cg");
                 } catch(Exception e){
               try {
                   DBUtil.rollback();
                   DBUtil.closeConnection();
               } catch (Exception e1) {
                   e1.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
               }
               e.printStackTrace();         }  }
            return forward;
        }}事务处理是:public boolean delete_kehuxinxi(String weijibianma)
       throws Exception {
            String strsql;
            String aaa = null;
            PreparedStatement ps = null;
             strsql="delete from kehuxinxi1 where WEIJIBIANMA ='" +weijibianma+ "'";        try {
             Connection conn = DBUtil.getCurrentConnection();
                ps = conn.prepareStatement(strsql);
                 ps.execute();
                  return true;
                 } catch (Exception ex) {
                ex.printStackTrace();
            } finally {
                  DBUtil.freeStatement(ps);
                try {
                    DBUtil.closeConnection();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
                 return false;
        }
      

  7.   

    楼主的这种Action的用法我没用过
    在struts中一般都是继承Action类重写execute()方法
