When i m trying to get data in textbox as readonly from database i m getting following error.and my code is shown below.

<%
String empid=(String) session.getAttribute("empid");
ResultSet rs=null;
Statement stmt=null;

try{
    Class.forName("oracle.jdbc.driver.OracleDriver");
    Connection con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","adm","adm");
    stmt=con.createStatement();
    rs=stmt.executeQuery("select fname,empid from cremp where empid='"+empid+"'");
    rs.next();

Here is a jsp code that retrieves data from database and display it on the textboxes.

<%@page language="java"%>
<%@page import="java.sql.*"%>
<table border="1">
<%
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root");
String query = "select * from employee where id='1'";
Statement st = conn.createStatement();
ResultSet rs = st.executeQuery(query);
if(rs.next()){
%>
<tr>
<tr><td>Name</td><td><input type="text" name="name" value="<%=rs.getString("name")%>"></td></tr>
<tr><td>Address</td><td><input type="text" name="address" value="<%=rs.getString("address")%>"></td></tr>
<tr><td>Contact No</td><td><input type="text" name="contact" value="<%=rs.getInt("contactNo")%>"></td></tr>
<tr><td>Email</td><td><input type="text" name="email" value="<%=rs.getString("email")%>"></td></tr>
<%
}
}
catch(Exception e){}
%>
</table>
