Any problem with the following jsp code?
<%@ page import="
java.io.*,
java.util.*"
%>
<%
boolean login_ok = false;
Boolean result_obj = new Boolean(login_ok);
result_obj = (Boolean)request.getAttribute("result");
login_ok = result_obj.booleanValue();
%>
<html>
<head>
<title>Login results page</title>
</head>
<body>
<%
if (login_ok){
%>
<p>Login Successful!</p>
<%
}
else{
%>
<p>Login Failure!</p>
<%
}
%>
</body>
</html>
It returns the following error:
Exception in jsp: null
java.lang.NullPointerException
