I have a problem with my injection, it's the first time I try it. I'm working with Wildfly and Java EE 7. I've got a NullPointerException when trying to access Authenticator instance in LoginController.
I use maven, my beans.xml is found under src/main/webapp/META-INF but I'v tried to put it in src/main/webapp/WEB-INF/classes without success.
Here is my code :
The class to inject :
@Stateless public class Authenticator { @Inject HashGenerator hashGenerator; @Inject UserPersistance userPersistance; public boolean authenticate(final String username, final String password) { User user = userPersistance.getUser(username); String salt = user.getSalt(); String hash = hashGenerator.hash(password, salt); return user.getPassword().equals(hash); } } The controller which throw NullPointerException :
@Stateless public class LoginController { @Inject Authenticator authenticator; public void login(String username, String password) { if (authenticator.authenticate(username, password)) { UI ui = UI.getCurrent(); ui.getSession().setAttribute(SessionAttribute.USER.getAttributeName(), username); ui.getNavigator().navigateTo(MainView.getName()); } } } And my beans.xml (Under src/main/webapp/META-INF)
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd" bean-discovery-mode="all"> </beans> What did I do wrong?
UPDATE
Sorry, I previously miswritten the folders name of beans.xml.
So, just to be clear, maven generate a WAR archive, and I've previously tried to put beans.xml under META-INF , WEB-INF and WEB-INF/classes. None of those folder seems to make it work. I've checked (tried and it works) a quickstart project from JBoss AS 7, and they put beans.xml under WEB-INF. I've done the same.
I think that maybe it comes from my Maven configuration. Here it is :
