Authentication using Seam Remoting

22. May 2008, 22:38 CET | Link Senthilkumar Peelikkampatti

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.

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

@Autocreate
EvolveAuthLocal 

<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()});

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