just add `checked` to whichever you want to be checked by default — SparkOn, Jul 11 '14 at 14:43

Try to use JSTL & EL instead of Scriplet elements. For database access use JSTL SQL Tag library or it's better to move the database code in the Servlet.

Try with the CSS Input Radio checked Property

Sample code:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<c:set var="gender" value="female"/>

Male <input type="radio" name="R1" 
            value="Male" <c:if test="${gender=='male'}">checked</c:if>>
Female <input type="radio" name="R1" 
            value="Female" <c:if test="${gender=='female'}">checked</c:if>>

Have a look at the similar post

EDIT

For check box values single value its show properly but when it multiple values showing nothing.

check the string using contains method.

sample code:

<c:set var="medium" value="Hindi Kannada" />

English
<input type="checkbox" name="C1"
    <c:if test="${medium.contains('English')}">checked</c:if>>
Kannada
<input type="checkbox" name="C1"
    <c:if test="${medium.contains('Kannada')}">checked</c:if>>
Hindi
<input type="checkbox" name="C1"
    <c:if test="${medium.contains('Kannada')}">checked</c:if>>

Ít's working fine. To test it just change the value of gender in the example. – Braj Jul 12 '14 at 13:23

follow the links that I have shared you in the post for JSTL and EL. – Braj Jul 12 '14 at 13:25
in the same case For check box values single value its show properly but when it multiple values showing nothing . – Shreenivas Jul 12 '14 at 14:13
You are talking about more than 3 radio buttons. – Braj Jul 12 '14 at 14:14
how are you getting multiple values from server? Is it in array? – Braj Jul 12 '14 at 14:19
print the value of medium `${medium}` and let me know what it contains. – Braj Jul 12 '14 at 14:24
when i print its showing Kannada Hindi both . because i have selected both while inserting into database. – Shreenivas Jul 12 '14 at 14:27
"The function contains must be used with a prefix when a default namespace is not specified". I got This Error – Shreenivas Jul 12 '14 at 14:35
It's related to prefix that is using for JSTL tags as I declared `c` for core tag in the post. – Braj Jul 12 '14 at 14:36
It's time to post another question with your sample code. – Braj Jul 12 '14 at 14:46
