JSF application with @EJB

I am creating Java application that uses JSF with @EJB injection. Does your server support that because I always get null for "userBeam" that is defined in @ManagedBean when I call loginBean.loginProject from xhtml file. If I call it from Webservlet then it works. I am using trial account.

Code example:

LoginBean.java

@ManagedBean(name = "loginBean")

@SessionScoped

public class LoginBean implements Serializable {

private static final long serialVersionUID = 1L;

private String password;

private String message, uname;

@EJB

UserBeam userBeam;

public String getMessage() {

return message;

}

public void setMessage(String message) {

this.message = message;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

public String getUname() {

return uname;

}

public void setUname(String uname) {

this.uname = uname;

}

public String loginProject() {

if (userBeam == null) <-- userBeam IS NULL

{

System.out.println("userBeam == null");

}

boolean result = userBeam.login(uname, password);

}

public String logout() {

HttpSession session = Util.getSession();

session.invalidate();

return "login";

}

}

UserBeam.java

@Stateless

@LocalBean

public class UserBeam {

@PersistenceContext

private static EntityManager em;

public List<User> getAllPersons() {

System.out.println("getAllPersons()");

return em.createNamedQuery("AllUsers").getResultList();

}

public void addUser() {

User newUser = new User();

newUser.setFirstName("name");

newUser.setLastName("surname");

newUser.setUsername("user");

newUser.setPassword("pass");

newUser.setPhone("054354353");

newUser.setCompany("Company");

em.persist(newUser);

em.flush();

}

public boolean login(String user, String password) {

System.out.println("login(String user, String password)");

System.out.println("USER: " + user + " PASS: " + password );

return true;

}

}

    Hello,

    I cannot reproduce your scenario.

    I tried with your example and I received:

    login(String user, String password)

    USER: Vily PASS: G

    Is it possible to share with us your application so that we can check what might be the problem.

    Regards,

    Violeta
