Hi Friend,
Create table country(country_id,country) in database and try the following code:
<%@page import="java.sql.*"%>
<html>
<form name="form" method="post" >
<b>Select a country:</b> </td>
<select name="sel"><option value=""><---Select---></option>
<%
Class.forName("com.mysql.jdbc.Driver").newInstance();
String connectionURL = "jdbc:mysql://localhost:3306/test";;
Connection connection= DriverManager.getConnection(connectionURL, "root", "root");
PreparedStatement psmnt = connection.prepareStatement("select * from country ");
ResultSet results = psmnt.executeQuery();
while(results.next()){
String name = results.getString(2);
String id = results.getString(1);
%><option value="<%= name %>">
<% out.println(name); %>
</option>
<%} results.close(); psmnt.close(); %>
</select><br>
<input type="submit" value="Submit"/><br>
</form>
<%String option=request.getParameter("sel");
if(option==null){
}
else{%>
<input type="text" value="<%=option%>">
<%
}
%>
</html>
Thanks
