Question

Platform I am using:

  • Fedora 20;
  • mariadb-5.5.34-2.fc20.x86_64;
  • Eclipse Kepler Service Release from www.eclipse.org;
  • Apache TomEE plus 1.6.0.

I am implementing example

See here

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.

Login.xml

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.

TomEE configuration

TomEE is using directories:

  1. Main TomEE directory: apache-tomee-plus-1.6.0-JAAS
  2. Eclipse's Servers workspace directory: /workspace/Server/TomEE-JAAS-config/

What is inside apache-tomee-plus-1.6.0-JAAS/config/ (1):

.
├── catalina.policy
├── catalina.properties
├── context.xml
├── groups.properties
├── logging.properties
├── login.config
├── server.xml
├── server.xml.original
├── system.properties
├── tomcat-users.xml
├── tomcat-users.xml.original
├── tomee.xml
├── users.properties
└── web.xml

0 directories, 14 files

What is inside (2):

.
├── catalina.policy
├── catalina.properties
├── context.xml
├── server.xml
├── tomcat-users.xml
└── web.xml

I uploaded both conf dirs HERE so you can consult them.

To configure TomEE to operate with JAAS, I asked the following question: So I configured TomEE in Eclipse in this way

Solution

Changing the attribute of the commandButton's tag to actionListener instead of action should resolve the problem.
