Retrieve data from database

Using Mysql database

1)page1.jsp:

<%@page import="java.sql.*"%>
<%@page language="java" import="java.util.*" %>

<form method="post" action="page2.jsp">
<table border=1>
<tr><th>ID</th><th>Name</th><th>Address</th></tr>
<%
ArrayList list=new ArrayList();
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root");
Statement st=con.createStatement();
ResultSet rs=st.executeQuery("select * from data");
while(rs.next()){
%>
    <tr><td><%=rs.getInt("id")%></td><td><%=rs.getString("name")%></td><td><%=rs.getString("address")%></td></tr>
<%
    list.add(rs.getInt("id"));
}
session.setAttribute("assid",list);
rs.close();
st.close();
con.close();
}
catch(Exception e){}
%>
<tr><td></td><td></td><td><input type="submit" value="Submit"></td></tr>
</table>
</form>

2)page2.jsp:

<%@page language="java" import="java.util.*" %>
<%Iterator itr;%>
<% List data= (List)session.getAttribute("assid");
for (itr=data.iterator(); itr.hasNext(); )
{
out.println(itr.next()+"<br>");
}
%>

thank u for ur reply...but we require the driver to be interfaced with oracle , we had made the necessary changes but the output is not obtained. we are getting a list of all the IDs and not the corresponding ID's information. Please assist us in this regard.
