Add this code in between the head tags of the page


<script type="text/javascript">
function Process(){
var frm = document.form1;
var len = frm.length;
for(n=0;n<len;n++){
if(frm[n].type=="radio" && frm[n].checked){
return true;
}
}
alert("You must make a selection from the radio boxes")
return false;
}
</script>


Then update your form tag as below

<form name="form1" action="/bms/servlet/adminservlet" onsubmit="return Process();" method="post">

And it should validate now that at least 1 radio button is checked ,
if it is checked the form will be submitted or an error is displayed and form will not be submitted.
