谁会Struts标签多行提交?

今天早上又有按照上面说的写一个用数组方法的：
但是还是不行，得不到客户端输入的值，
可以显示程序已经所给的数组准确的值
接受页面没有错误页面出现，接受的还是程序所给的，非更新值
下面是struts-config.xml配置文件
<form-bean name="string_Teacher_Form" type="string_teacher.String_Teacher_Form" >
     <form-property name="teacher_no" type="java.lang.String[]" />
     <form-property name="teacher_name" type="java.lang.String[]" />
</form-bean>
……
<action name="string_Teacher_Form" parameter="method" path="/string_teacher/string_teacher" type="string_teacher.String_Teacher_Action">
      <forward name="view" path="/string_teacher/string_teacher_view.jsp" />
      <forward name="do_message" path="/string_teacher/do_message.jsp" />
    </action>
String_Teacher_Form.java
public class String_Teacher_Form extends ActionForm {
    private String[] teacher_no;
    private String[] teacher_name;
    public ActionErrors validate(ActionMapping actionMapping,
                                 HttpServletRequest httpServletRequest) {
            /** @todo: finish this method, this is just the skeleton.*/
        return null;
    }    public void reset(ActionMapping actionMapping,
                      HttpServletRequest servletRequest) {
    }    public void setTeacher_no(String[] teacher_no) {
        this.teacher_no = teacher_no;
    }    public void setTeacher_name(String[] teacher_name) {
        this.teacher_name = teacher_name;
    }    public String[] getTeacher_no() {
        return teacher_no;
    }    public String[] getTeacher_name() {
        return teacher_name;
    }
}
下面是String_Teacher_Action.java
public class String_Teacher_Action extends DispatchAction
{
    public ActionForward view(ActionMapping mapping, ActionForm form,
                                 HttpServletRequest request,
                                 HttpServletResponse response) {
        String_Teacher_Form m_form = (String_Teacher_Form) form;
        int m_row=50;
        String[] teacher_name = new String[m_row];
        String[] teacher_no = new String[m_row];
        for(int i=0;i<m_row;i++)
        {
            teacher_name[i]="teacher_no:"+(i+1);
            teacher_no[i]="teacher_name:"+(i+1);
        }
        m_form.setTeacher_name(teacher_name);
        m_form.setTeacher_no(teacher_no);
        request.setAttribute("form",m_form);
       return mapping.findForward("view");
    }
    public ActionForward do_message(ActionMapping mapping, ActionForm form,
                             HttpServletRequest request,
                             HttpServletResponse response) {
    String_Teacher_Form m_form = (String_Teacher_Form) form;
    request.setAttribute("form",m_form);
   return mapping.findForward("do_message");
}}下面是string_teacher_view.jsp代码
<html:form action="/string_teacher/string_teacher.do?method=do_message" method="POST" >
<table align="center" width="80%" border="1" cellpadding="4" cellspacing="1" bordercolor='red'>
<tr><td>teacher_name</td><td>teacher_no</td></tr>
<logic:iterate id="item" name="form" property="teacher_name" indexId="index">
<tr>
<td>  <html:text  name="form" property="<%="teacher_name["+index+"]"%>" indexed="true"/></td>
<td>  <html:text  name="form" property="<%="teacher_no["+index+"]"%>" indexed="true"/></td>
</tr>
</logic:iterate>
</table>
<INPUT TYPE="submit" value="确定">
</html:form>下面是do_message.jsp
<html:form action="/string_teacher/string_teacher.do?method=view" method="POST" >
<table align="center" width="80%" border="1" cellpadding="4" cellspacing="1" bordercolor="steelblue" >
<tr bgcolor="steelblue"><td>teacher_name</td><td>teacher_no</td></tr>
<logic:iterate id="item" name="form" property="teacher_name" indexId="index">
<tr>
<td>  <html:text  name="form" property="<%="teacher_name["+index+"]"%>" indexed="true"/></td>
<td>  <html:text  name="form" property="<%="teacher_no["+index+"]"%>" indexed="true"/></td>
</tr>
</logic:iterate></table>
<INPUT TYPE="submit" value="确     定" >
</html:form>以前这种情况的接受会出现
javax.servlet.ServletException: BeanUtils.populate
这样的错误，但是现在不出现了，但是却得不到客户端的输入更新值
还是以前的值
为何？
a_lone_bird 跟楼主是同一个人？还是什么关系？
