How to set value to radio button/check box dynamically

[B Manikandan]

Hi,
   When a form is loaded how to set the value of radio buttons/check
boxes.
I have a property in my bean whose value has to be set in radio
button/check box.

But,if I use

<html:radio name="domainDomainRelationHolder" property="childGroupOID"
value="childGroupOID"/>

all that Iam getting is  a radio button with value="childGroupOID".But I
need the value of childGroupOID from bean class
DomainDomainRelationHolder as value of my radio button.
