Session bean in Struts2

I'm trying to create a simple session with a stateful bean using Struts2, but every time I resubmit my request and try to get the information previously placed in my stateful bean, it returns NULL. Am I missing something?

The injection works correctly after registering, but when I make a new request with the retrieve method in the activity class, I cannot get my session information as it returns null.

How can i do this?

Ignore locks, I used them just to test other functions. you can ignore them. I repeat that injection works correctly when the method is executed

public class Registration extends ActionSupport implements ModelDriven<Account> {
    private static final long serialVersionUID = -8930461193700155653L;
    private Account account;
    private User user;

    @Inject // this is the interface implemented by my stateful bean
    AccountServiceLocal asl;

    @Inject
    PassHashInterface phi;

    @Inject
    UserServiceLocal usl;
    private final Lock lock =new ReentrantLock();

    @org.apache.struts2.interceptor.validation.SkipValidation
    public  String retrieve(){      
        if(asl.getEmail()!=null){ // always null        
            return "success";           
        }
        return "input";
    }
    public  String execute() throws NoSuchAlgorithmException,
                                    InvalidKeySpecException, 
                                    InterruptedException {

        user=new User();
        user.setEmail(account.getEmail().toString().trim());         
        System.out.println("in execute");
        account.setRole("Regular");
        account.setPwd(phi.createHash(account.getPwd()));
       /*
        * NB. the primary key in Account(AccountId) does not
        * Necessary matches the primary key in User(Id) 
        */         
        asl.create(account);
        usl.create(user);
        lock.unlock();          
        return "success";            
    }

    @Override
    public Account getModel() {
        account=new Account();
        return account;
    }
}
