    Why second instance of weld bean got instantiated?

    Roshan Mutha Newbie

      Hi

       

      I am having login page where i enter username and password and click on login button.

       

      i am having weld bean for user credential as follows,

       

      @Named

      @SessionScoped

       

      public class Credentials implements Serializable {

       

          /**

           *

           */

          private static final long serialVersionUID = 8154140549591434736L;

          private String username;

          private String password;

       

          public String getUsername() {

              return username;

          }

       

          public void setUsername(String username) {

              this.username = username;

          }

       

          public String getPassword() {

              return password;

          }

       

          public void setPassword(String password) {

              this.password = password;

          }

       

      }

       

      i had added eclipse debuger on setter methods ,then i found that it set the value to bean but the class where i inject this bean is second bean and not one which is populated from JSF Form.

       

      @Inject private Credentials credentials;

       

      Above code i used to inject credentials in Authenticator class,

       

      import javax.enterprise.context.RequestScoped;

      import javax.enterprise.context.SessionScoped;

      import javax.faces.application.FacesMessage;

      import javax.faces.context.FacesContext;

      import javax.inject.Inject;

      import javax.inject.Named;

      import javax.servlet.http.HttpSession;

       

      import org.slf4j.Logger;

      import org.slf4j.LoggerFactory;

       

       

      @Named

      @RequestScoped

      public class Authenticator implements Serializable{

          //@Inject private Logger log;

          private static final Logger log=LoggerFactory.getLogger(Authenticator.class);

       

       

        

          @Inject private Credentials credentials;

       

       

          public String authenticate()

          {   

              System.out.println(credentials.getUsername());

          }

       

          public void logout()

          {

       

          }

      }

       

       

      Please tell me that why second instance of bean is being instantiated by container?

       

      Thanks in adavnce.
