I am trying to implement the working example for <user-data-constraint>. I am unable to understand when and where I will get this 301 code , when will this redirection happen. Do any body happen to have a small snippet of working code which will demonstrate it to me.

because this is the web.xml file that I have written.



I am unable to access the index.jsp pages in /Beer/AddRecipe and /Beer/ReviewRecipe. Previously I used to get this before i put <user-data-constraint. It used to ask me for username and password.

And also I want to implement the form authentication. Which is not working.
the index.html file is



What changes I have to make it work.

Everything was working till I introduced <form> authentication, and introduces <user-data-constraint> Please help me to solve the problem

Hi Anil.
I am unable to understand when and where I will get this 301 code , when will this redirection happen.

When a request comes, container sees is there defined in <security-constraint>? If yes, it will send 301 code to the browser. Then the browser enables https and comes to container. Basically container will deal with http requests, i.e on port no. 8080.
We have to change the settings in tomcat/conf/server.xml (enable connector on port 8443) and also we need jsse api. For more information see this.

Is the working example on this is beyond the scope of this SCWCD. Bacause even in Head first Servlets and JSP, they have not given the working example code

We have to know there is a element inside <user-data-constraint> and its purpose.
