ssh多对多如何在jsp页面输出?

这是查询所有的结果集
//显示所有 controller控制层
public String findAll(){
if (page==null) {
page=new PageUtil();
}
page.setTotalCount(teastuService.queryCount(each));

HttpServletRequest request = ServletActionContext.getRequest();
teaList=teastuService.findAll(each,page);

if(teaList.size() < 1 ){
    request.setAttribute("eachNo", "没有此条信息!");
}
request.setAttribute("teaList", teaList);
return "showList";

}

这是dao下的方法
@Resource(name="sessionFactory")
SessionFactory sessionFactory;
public List findAll(String each,PageUtil page) {
Session session = sessionFactory.openSession();
String eachType="%"+each+"%";
Query query=session.createQuery("select t from Teacher t where t.TName like '"+eachType+"'");
query.setFirstResult(page.getPageIndex()*page.getPageSize()-page.getPageSize());
query.setMaxResults(page.getPageSize());

    List<Teacher> list = query.list();

    session.close();
    return list;
}

Student实体类

        this.teachers = teachers;

    public void setTeachers(Set<Teacher> teachers) {
        this.teachers = teachers;
    }
Teacher实体类

    }

    @Column(name = "t_name", length = 50)
    public String getTName() {
        return this.TName;
    }

    public void setTName(String TName) {
        this.TName = TName;
    }

    }

    public void setStudents(Set<Student> students) {
        this.students = students;
    }

jsp页面输出显示

<form action="teaStuController!deleteMore" onsubmit="return delMore()" method="post"  >
   <table  style="text-align: left" width="800px" >
    <tr>
        <th  id="t1"><input id="qx" type="checkbox" onchange="quanxuan()"/>全选</th>   
       <th>编号</th>
       <th>学生姓名</th>
       <th>老师姓名</th>
        <th><a  href="teaStuController!addpage">添加</a></th>
    </tr>
  <s:iterator var="tea"  value="#request.teaList">

     <tr>
        <td><input type="checkbox"  name="ids" value="<s:property  value="#tea.TId"/>"/></td>           
         <td><s:property  value="#tea.TId"/></td>
         <td>
                        ????????????(这位迭代一直报错)
         </td>
         <td><s:property  value="#tea.TName"/></td>

           <td> <a  href="teaStuController!updatePage?teacher.TId=<s:property  value="#tea.TId"/>"> 修改</a>  
                    <a  href="teaStuController!deleteOne?teacher.TId=<s:property  value="#tea.TId"/>"> 删除</a>  
           </td>
     </tr>
   </s:iterator>

 我中间用了C标签迭代报错,后来改用S标签迭代几次还是报错,求教大神 多对多这里应该怎么迭代,还是我其他代码错了,谢谢了.

这个地方改一下

@Resource(name="sessionFactory")
SessionFactory sessionFactory;
public List findAll(String each,PageUtil page) {
Session session = sessionFactory.openSession();
String eachType="%"+each+"%";
Query query=session.createQuery("select t from Teacher t where t.TName like '"+eachType+"'");
query.setFirstResult(page.getPageIndex()*page.getPageSize()-page.getPageSize());
query.setMaxResults(page.getPageSize());
