一个新手jsp页面的问题

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
    <%@ page language="java" import="java.sql.*" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<% Connection con=null;
PreparedStatement ps=null;
ResultSet rst=null;
  
  try{
  //1.加载驱动 loading driver
  Class.forName("oracle.jdbc.driver.OracleDriver");
 
  //2.得到连接 get connection
  con=DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:orcl","system","3333");
 
  //3.创建preparedstatement借口对象
  ps=con.prepareStatement("select * from aaa");
 
  //4.完成查询 finish the select
  rst=ps.executeQuery();
 
  //5.循环输出结果
  while(rst.next()){ %>
   
   <%=rst.getInt(1)%> <%}
  }catch (Exception e){
 
  }finally {
  } %>
</body>
</html>我是想让这里<%=rst.getInt(1)%> 把查询结果输出到jsp页面的， 可是出不来啊
