Hi
what is the wrong in my code?why the radio options do not appear?
I checked the value and it is correct,so why the values do not appear in options

(see the radio options in the code)
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@ page import="java.sql.*,java.io.*,java.util.*,org.apache.*,java.io.File,java.lang.*"%>

The taglib directive below imports the JSTL library. If you uncomment it,
you must also add the JSTL library to the project. The Add Library... action
on Libraries node in Projects view can be used to add the JSTL 1.1 library.

You get the same field twice with rs.getString.  The second time, it doesn't exist.  You should have a SQLException in your logs -- if you check, it will tell you the line number of your file which has the problem.

Change your code to something like this:
  String myVar = rs.getString("software_name");

and use <%=myVar%> for the HTML values.
