    WELD-001414 Bean name is ambiguous - Understanding @Any @Default

    infinity2heaven Novice

      I have a sample project extending weld-login example that comes with weld-1.1 dist.


      Bean


      @Model
      public class Credentials {
      
          private String username;
          private String password;
      }
      



      Authenticator


      @SessionScoped
      @Named
      public class Authenticator
           implements Serializable {
      
           
           private static final long serialVersionUID = 1L;
      
           @Inject
           private Credentials credentials;
      
           private User currentUser;
      
           @PersistenceContext
           private EntityManager em;
           
           @SuppressWarnings( "unchecked" )
           public void login() {
      
                List< User > results =
                     em.createQuery(
                          "select u from User u where u.credential.username=:username and u.credential.password=:password" ).setParameter(
                          "username",
                          credentials.getUsername() ).setParameter( "password", credentials.getPassword() ).getResultList();
      
                if ( !results.isEmpty() ) {
                     currentUser = results.get( 0 );
                     FacesContext.getCurrentInstance().addMessage(
                          null,
                          new FacesMessage( "Welcome, " + currentUser.getName() ) );
                }
      
           }
      
           public void logout() {
      
                FacesContext.getCurrentInstance().addMessage(
                     null,
                     new FacesMessage( "Goodbye, " + currentUser.getName() ) );
                currentUser = null;
           }
      
           public boolean isLoggedIn() {
      
                return currentUser != null;
           }
      
           @Produces
           @LoggedIn
           public User getCurrentUser() {
      
                return currentUser;
           }
           
           @SuppressWarnings( "unchecked" )
           @Produces
           @Named
           @RequestScoped
           public List< User > getUsers() {
      
                return em.createQuery( "select u from User u" ).getResultList();
           }
      
      }
      



      I get the following on deploying to JBoss 6.0. I'm using Sea, 3.0 beta, Seam-solder jars in my war file. And that's the only difference from the weld-login project (which I'm abel to run and deploy).



      WELD-001414 Bean name is ambiguous. Name credentials resolves to beans [Managed Bean [class xxx.security.Credentials] with qualifiers [@Any @Default], Managed Bean [class org.jboss.seam.security.CredentialsImpl] with qualifiers [@Any @Default @Named]]
           at org.jboss.weld.bootstrap.Validator.validateBeanNames(Validator.java:472) [:6.0.0.Final]
      



      I don't think I understand the concepts of @Any, @Default at all. What is the wrong with the above code (since it works in the example project)
