Platform I am using:
I am implementing example
and I am trying to manage to work the login interface. My problem is that the login.xhtml webpage gets correctly the username and password, but the method
public void login(ActionEvent actionEvent)
of bean LoginController.java does not react correctly to the webpage login button. In particular, the webpage does not say anything about the correctness of the username & password. To see what it should happen, see the interactive example at the previous link. Here instead, a short video of what happens on my computer.
To find out what is going on, I putted some console outputs inside the Java bean, and I found out that the getter/setter methods are working, the only method that does not work is
public void login(ActionEvent actionEvent)
Indeed the print
System.out.println("Entering in public void login(ActionEvent actionEvent)");
does not appear in console.

I have also tried to replace
<p:commandButton value="Submit" update="msgs" action="#{loginController.login}" icon="ui-icon-check" style="margin:0" />
with
<p:commandButton value="Submit" update="msgs" action="#{loginController.login}" icon="ui-icon-check" style="margin:0" />
but the result is the same.

To configure TomEE to operate with JAAS, I asked the following question: So I configured TomEE in Eclipse in this way
TomEE console:
Changing the attribute of the commandButton's tag to actionListener instead of action should resolve the problem.
