怎么在jsp页面中利用组件调用.class文件显示多行数据

<% int i=0,s=0,uid=0,yid=0;
    String  uquestion="";
if(!showy.checkexam()){//判断是否存在试题
  if(showy.showexam()){//如果存在，显示试题的题号和题目内容
  s=showy.getsum();
  uid=showy.getfid();
  uquestion=showy.getfquestion();
  yid=showy.getmid();
  %>
  <table width="64%" height="44" border="0" align="center">
  <tr>
    <td width="15%">题号</td>
    <td width="38%">题目</td>
    <td width="18%">修改</td>
    <td width="29%">删除</td>
  </tr>
  <tr>
    <td><%=uid%></td>
    <td><%=uquestion%></td>
    <td><a href="xmanageamendexam.jsp?xid=<%=uid%>&tid=<%=yid%>">修改</a></td>

上面的代码只能显示一行数据（题号和题目内容）
  请问各位高手怎么写代码显示多行数据  （要求：在showexam.java中从数据库提取多行数据，然后在jsp页面中利用组件把showexam.class中的数据给提出并显示）
  帮帮忙！！！
<tr>
    <td><%=uid%></td>
    <td><%=uquestion%></td>
    <td><a href="xmanageamendexam.jsp?xid=<%=uid%>&tid=<%=yid%>">修改</a></td>
    <td><a href="xmangedelokexam.jsp?cid=<%=yid%>">删除</a></td>
  </tr>
要放在if(rs.next())
{
}
循环里

多谢任我行大侠的帮帮！！！！  但能不能用.java文件来处理
   if(rs.next()){
  //取数据（取出会员的id和会员名） }
//在.class文件中完成提取多行数据的操作然后在Jsp页面中利用组件把.class文件提取的数据一一在页面中显示！  再帮帮忙，想想！
我 up!
