问题是这样的。我从后台数据库中取出记录集，然后在前台JSP页面中显示。希望以多行多列来显示。可是代码中却要把显示多行要么显示多列。。。。。
类如下：
//取出精品记录
    public Collection JingPin(){
       String str="select * from zqc.product where jingpin='1'";
       linkoracle jd=new linkoracle();
       Vector v=new Vector();
       conn=jd.getConn();
       stmt=jd.getStatement(conn);
       try {
           rs = stmt.executeQuery(str);
        while(rs.next()){
            product p=new product();
            p.setBianHao(rs.getString("bianhao"));
            p.setName(rs.getString("name"));
            p.setImage(rs.getString("image"));
            p.setPrice(rs.getString("price"));
            p.setCaiLiao1(rs.getString("cailiao1"));
            p.setCaiLiao2(rs.getString("cailiao2"));
            p.setCaiLiao3(rs.getString("cailiao3"));
            p.setCaiLiao4(rs.getString("cailiao4"));
            p.setCaiLiao5(rs.getString("cailiao5"));
            p.setCaiLiao6(rs.getString("cailiao6"));
            p.setCaiLiao7(rs.getString("cailiao7"));
            v.add(p);
        }
       } catch (SQLException ex) { }

      return v;
   }

前台显示部分如下：
<%product p=new product();
          
         int j=0;
         for(int i=0;i<2;i++){
         Iterator coll=p.JingPin().iterator();
         
        %>
        <tr align="center" valign="top">
        
         <%while(coll.hasNext()&&j<2){
           product plist=(product)coll.next();
           %>
          <td width="192">
          <table width="180" height="180" border="0">
            <tr>
              <td height="120" align="center" valign="top"><a href="/Product/ProductDetail.asp?ProductID=54"><img name="flower" src="flowers/<%=plist.getImage()%>" width="100" height="110" alt="" border="0"></a></td>
            </tr>
            <tr>
              <td align="center" valign="middle"><A href="/Product/ProductDetail.asp?ProductID=54" class="style68"><%=plist.getName()%></A></td>
            </tr>
            <tr>
              <td align="center" valign="middle"><span class="style69">￥<%=plist.getPrice()%></span></td>
            </tr>
          </table>
          </td>
         <%j++;}%>
          </tr>
        <%}%>
