I added the following login-config and security-constraint to my web.xml: <!-- Redirect access of restricted pages to index.jsp --> <login-config> <auth-method>FORM</auth-meth...
Is there an argument to be made for/against checking for authentication in every JSP? Maybe via a custom tag or some such thing. The argument that I am hearing is that it is useful to show different content based on the user authentication state. If I use a filter or container managed security that means I can protect a set of director...

I am fairly new to Tomcat. I just managed to build a project and exported it as a WAR file. I tried manually copying a WAR file to the Tomcat folder then restarting. It created the folder structure and everything but I get a 404 Status code when I try to reach the application. I tried deploying it through the Tomcat Admin panel but I'm s...
Hey guys, I have this webprojec to which I have to add a jar from another EJB project. Normally I'd right-click the webproject and go to properties -> Java EE Module Dependencies.
