While trying this code,it shows this error in the string line.
<%
String error = (String)request.getAttribute("error");
request.removeAttribute("error");
if(error != null)
out.println(error);
%>
Thanks!
If you want to get the string try this:
<%
String error = (String)request.getParameter("error");
request.removeAttribute("error");
if(error != null)
out.println(error);
%>
getAttribute()
returns an Object, getParameter
returns the Value of the Query String
