Seam action problem

[dmrc]

Hello
i am using Jboss Tools. i have a user entity and registerAction.

`
@Entity
@Name("User")
public class user implements Serializable
{
    // seam-gen attributes (you should probably edit these)
    private Long id;
    private Integer version;
    private String name;

    // add additional entity attributes

    // seam-gen attribute getters/setters with annotations (you probably should edit)

    @Id @GeneratedValue
    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    @Version
    public Integer getVersion() {
        return version;
    }

    private void setVersion(Integer version) {
        this.version = version;
    }

    @Length(max = 20)
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

`

`
@Scope(ScopeType.SESSION)
@Name("registerAction")
public class RegisterAction
{
    @Logger private Log log;

    @In StatusMessages statusMessages;
   
    @In protected user newUser;
   
    @In protected EntityManager entityManager;

    public void registerAction()
    {
        // implement your business logic here
        log.info("registerAction.registerAction() action called");
        statusMessages.add("registerAction");
       
    }

    public String register(){
        entityManager.persist(newUser);
        return "/userList.xhtml";
       
    }
    // add additional action methods

}

And this register action not working. i am trying action=#{registerAction.register()} and  i am getting below errors :
