This is my web.xml file, it is located in WEB-INF/lib. It specifies session timeout at 1 minute, however it does not time the user out after 1 minute of activity.
Web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<servlet-name>Login</servlet-name>
<servlet-class>Login</servlet-class>
</servlet>
<servlet-mapping>

<url-pattern>/Login</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>1</session-timeout>
</session-config>
</web-app>
I used this line session.getMaxInactiveInterval() in my jsp file and it outputted 1800 (30 minutes) . Does anyone why it defaults to 30 rather than using the time specified in my web.xml file?
EDIT:
I've code on my jsp page which checks for session attribute and if it does exist redirects the user to the login page after a minute even on page refresh the user is not redirected.
if(session.getAttribute("username") != null){
out.println(session.getAttribute("username"));
}else{
response.setStatus(response.SC_MOVED_TEMPORARILY);
response.setHeader("Location", "index.jsp");
}
