Hi Friend,

Try this:

<%@page import="java.sql.*"%>
<html>
<script>
function ch(){
        document.getElementById('lab').innerHTML="Name";
        document.getElementById('txt').disabled=false;
    }
</script>
<form name="form">
<table>
<tr><td>Select</td><td><select id="sel" onchange="ch();">
<%
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","root");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("Select * from data");
while(rs.next()){
%>
<option value="<%=rs.getInt("id")%>"><%=rs.getInt("id")%></option>
<%
}
%>
</select></td></tr>
<tr><td><label id="lab" disabled="true"></label></td><td><input type="text" id="txt" disabled="true"></td></tr>
</table>
</form>
