Authentication using Seam Remoting

[sendtopms.senthilkumar.peelikkampatti.bnsf.com]

I am facing issues while authenticating user through Seam Remoting.
Here is the scenario,
I have a popup widget, which will obtain user/password from the user and onclick of login button it invokes SLSB and Identity.login and hence registered authenticator would be called from Seam. But it is not happening.
Here is Components.xml code

    <security:identity authenticate-method="#{serviceAuthenticator.authenticate}"/> 

Here is web.xml

<ejb-local-ref>
        <ejb-ref-name>evolve/EvolveAuthBean/local</ejb-ref-name>
        <ejb-ref-type>Session</ejb-ref-type>
        <local>evolve.user.ejb.EvolveAuthLocal</local>
        <ejb-link>EvolveAuthBean</ejb-link>
    </ejb-local-ref>
    <ejb-local-ref>
        <ejb-ref-name>evolve/AjaxLoginBeanBean/local</ejb-ref-name>
        <ejb-ref-type>Session</ejb-ref-type>
        <local>evolve.user.ejb.AjaxLoginBeanLocal</local>
        <ejb-link>AjaxLoginBeanBean</ejb-link>
    </ejb-local-ref>

Here is the Code for serviceAuthenticator, it is taken from seam booking example,

 
@Stateless
@Name("serviceAuthenticator")
public class EvolveAuthBean implements EvolveAuthLocal {
    @In
    Identity identity;
   public boolean authenticate() {
        this.loggedInUser = new User(identity.getUsername(), identity.getPassword(), identity.getUsername());
        return true;
    }
}

One more SLSB to do remoting and authentication,
Here is the code,

@Name("AjaxLogin")
@Stateless
public class AjaxLoginBeanBean implements AjaxLoginBeanLocal {
    @In (create=true)
    Identity identity;
    
    @WebRemote
    public User login(String userName, String password) {
        identity.setUsername(userName);
        identity.setPassword(password);
          String loggedIn = identity.login();
          return user;
    }
}

I got below errors,

But when I invoke login through JSF page, it is working without any issue.
Here is JSF working code,

                             <h:panelGrid columns="2" border="0" >
                                    <h:outputLabel for="name" value="Username"/>
                                    <h:inputText id="name" value="#{identity.username}"/>
                                    <h:outputLabel for="password" value="Password"/>
                                    <h:inputSecret id="password" value="#{identity.password}"/>
                                </h:panelGrid>
                                 <div align="center">
                                    <h:commandButton value="Login" action="#{identity.login}"/>
                          </div>
   

Please help me how to invoke login or authentication through seam remoting.

Just guessing:

@In(name="xxx", create=true)

or

@Autocreate
EvolveAuthLocal 

could help.

Personally I think the problem could be if EvolveAuthLocal doesn't have the @Local annotation present.

Once more: I'm just guessing.

[sendtopms.senthilkumar.peelikkampatti.bnsf.com]

without @Local OR @Remote you can't deploy ejbs, so I do have @Local.

I tried @AutoCreate on both the beans but it is not working.

[leonardinius]

One more guess:
By default Authenticator comes without @Stateless annotation.
I am not sure it changes something.

Additional inf is needed

• In JSF you have tried #identity resolving. What about a EvolveAuthBean which failed?


• Could you post Your remoting initialization code? I mean - what js/components are you included within and js code to call WebRemote method?

[sendtopms.senthilkumar.peelikkampatti.bnsf.com]

You are wrong - about stateless. You can look at any seam example (jee5), you can see @Stateless. #indetity - Please refer any seam example (jee5) it has same example.
I said with JSF it is working, but with remoting it is not working. I don't know what code you are refering but all i have is posted above.

When we use Seam Remoting without JSF, I doubt all the lifecycle call and context is not initialized. Is my assumption is correct? If so what should I do to initialize properly?

It fairly straigt forward as I pick it from Seam tutorial and it is working except for Authentication.

<script type="text/javascript" src="seam/resource/remoting/resource/remote.js"></script>

        <script type="text/javascript"

                src="seam/resource/remoting/interface.js?AjaxLogin"></script>

     var AjaxLogin = Seam.Component.getInstance("AjaxLogin");

           AjaxLogin.login (usr,pwd, function (){alert()});

I also tried with No param method as below(AjaxLoginBeanBean also has loginTest and its local interface also has this method)

AjaxLogin.loginTest (function (){alert()});

The call to AjaxLoginBeanBean is working but it is failing in Authentication.

I had good luck setting the username, password in the credentials component instead of the identity component.

     @In(create=true)
     Credentials credentials;
     
     @In(create=true)
     Identity identity;
     
     @WebRemote
     public String login(String username, String password){
          credentials.setUsername(username);
          credentials.setPassword(password);
          return identity.login();
     }
