Hi every body, I tried to search for my own problem, I would think this must be popular issue but unfortunately I found no solution in Google.
I tried to use (boolean) session.getAttribute("IsValidUser") to get the attribute of Session, but that caused error:
org.apache.jasper.JasperException: PWC6033: Error in Javac compilation for JSP
PWC6197: An error occurred at line: 8 in the jsp file: /WEB-INF/jsp/index.jsp
PWC6199: Generated servlet error:
inconvertible types
required: boolean
found: java.lang.Object
So below is my JSP code:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@page session="true" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<%! boolean IsValidUser = false ; %>
<% int LoginTriesTime = 0 ;%>
<% String UserName = "" ;%>
<%
try
{
IsValidUser = (boolean) session.getAttribute("IsValidUser") ; //THIS IS WHERE THE ERROR CAUSED
}
catch (IllegalStateException Ex)
{
Ex.printStackTrace();
}
if (IsValidUser == true)
{
UserName = (String) session.getAttribute("UserName");
}
else
{
LoginTriesTime = (int) session.getAttribute("LoginTryTimes"); //THIS IS WHERE THE ERROR CAUSED
}
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Welcome to Spring Web MVC project</title>
</head>
<body>
<%
if (IsValidUser == true)
{
%>
<h3>Welcome <%= UserName %></h3>
<%
}
else
{
response.sendRedirect("login.jsp");
}
%>
</body>
</html>
Really appreciate if you guys can help me figure out this. I'm new to JSP
Many Thanks,
Tu Dinh
