component injection seam 1.2.1. ga

[ccode]

environment
jboss 4.2
seam 1.2.1

i have seam component

package iu.ce.ejb.service;
import javax.ejb.Local;
import iu.ce.entity.User;
@Local
public interface UserService {
 public User getUser(String username, String password);
}

import iu.ce.service.UserService;

import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.NoResultException;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;

import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Logger;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Out;
import org.jboss.seam.log.Log;
import org.jboss.seam.security.Identity;

@Stateless
@Name("userServiceBean")
public class UserServiceBean implements UserService {
 @In
 Identity identity;
 @Logger
 Log log;
 @PersistenceContext(unitName = "iuce")
 private EntityManager entityManager;


 public User getUser(String username, String password) {
 try {
 Query q = entityManager.createQuery("from User u where"
 + " username=:username and password=:password");
 q.setParameter("username", username);
 q.setParameter("password", password);
 return (User) q.getSingleResult();
 } catch (NoResultException e) {
 return null;
 }
 }
 public void authenticate() {
 log.info("authenticating #0", identity.getUsername());
 getUser("", "");
 //getUser("h","h");
 //userServiceBean.getUser("h", "h");
 // write your authentication logic here,
 // return true if the authentication was
 // successful, false otherwise
 identity.addRole("admin");
 //return true;
 }
}

authentication works fine

in application server log

00:47:29,153 INFO [Component] Component: userServiceBean, scope: STATELESS, type: STATELESS_SESSION_BEAN, class: iu.ce.bean.UserServiceBean, JNDI: iuce-ear/UserServiceBean/local

component seems installed

i have another component standart Authentication component which wizards creates.

when i tried to insert this

@In(create=true)
UserBeanService userBeanService

or

@In
UserBeanService userBeanService

it gives following error

In attribute requires non-null value ...

UserServiceBean returns null.

i want to learn how can i inject seam component to another component.

This is why because Seam is looking for beans via @Name.

So it should be looking like this:

@In
UserBeanService userServiceBean;

or if you need it to be created

@In(create = true)
UserBeanService userServiceBean;

[ccode]

sorry about name issue i did what you said but i accidently typed incorrectly.
i did your suggestion but i am getting null value error

[ccode]

oh sh.. why editing is not enabled.?

@In
UserServiceBean userServiceBean;

or

@In(create=true
UserServiceBean userServiceBean;

is not working

@In Identity identity;

Are you sure it is not this @In that is causing the exception? Maybe try create=true here as well.

[ccode]

Yes

@In(create = true)
UserBeanService userServiceBean;

this is causing the problem

[ccode]

sorry this

@In(create = true)
UserServiceBean userServiceBean;

Can you post a full stacktrace? I think that does occur is that you probably want to access the bean through it's local interface, i.e.

@In UserService userServiceBean;

thanks for the answer solution is using interface instead of bean itself
