In JSP radio button exception

I made two radio buttons like this: 

<input type="radio" name="One" value="Send To All" checked="checked" />  
    <input type="radio" name="One" value="Send To Recent" />

But when I tried to fetch the value of radio button via following line of code: 

request.getParameter("Send To All");

I got a NullPointerException on the same line. So can anyone tell me the right way to get the value of radio button?

Thanks in advance.

out.println(value);

Actually on server side we can access the form values by name attribute not with the value attribute

So it should be 

request.getParameter("One");

And the line it self won't give null pointer exception and it returns null value if there is no parameter with that name.

And as commented you have to check like 

    if(request.getParameter("One").equals("Send To All"){
       //TO DO
    }
