save selected radio button value in session scoped bean

[Ankita B]

Hi is there a way to save the selected radio box value into a session variable so that i can retrieve it and display on next page?..the selected value is displayed on the page but after navigation it shows the last value and not the selected one..

String upid = 	(String)enum.nextElement();
  	String upname = (String)enum.nextElement();
	
	myupbean=(UpBean)session.getAttribute("MyBean");
	myupbean.setUid(upid);
 	myupbean.setUname(upname);
	session.setAttribute("MyBean",myupbean);

value to be displayed in this page...

String id1 = request.getParameter("idradio");
String name1= request.getParameter("namerad");
				

if(id1 == null && name1 == null){
			myupbean=(UpBean)session.getAttribute("MyBean");

			if(myupbean != null) {
				id1=myupbean.getUid();
				name1=myupbean.getUname();

				myupbean.setUid(id1);
				myupbean.setUname(name1);
				session.setAttribute("MyBean",myupbean);


				
			} 
			else {
				id1= "";
				name1="";
			}

			
	}
	
	
%> 
input type="textbox" name="AQC1_UID" value="<%= id1 %>" >
