I tried to build a project with manages Employees using JPA and Beans and JSF. I started trying to manipulated an existing user which I manually created in the database. (before I tried to read the data from the database, this worked well) I tried this in various ways, by getting different errors, so I assume that I do somethinbg completely wrong. My Server is Wildfly 8 and database is postgresql.
15:09:43,410 ERROR [io.undertow.request] (default task-14) UT005023: Exception handling request to /time/modifyuser.jsf: javax.servlet.ServletException: Bei der Ressourcen-Einspeisung auf dem verwalteten Bean employeeManagerTool ist ein Fehler aufgetreten.

So here is my Bean:
@Stateless(name = "EmployeeManagerTool")
public class EmployeeManagerTool implements EmployeeManagerToolLocal {
@PersistenceContext(type=PersistenceContextType.EXTENDED)
private EntityManager entityManager;
public EmployeeManagerTool() {
}
public void modifyEmployee() {
Employee employee = entityManager.find(Employee.class, 1);
employee.setFirstName("NNF");
employee.setLastName("NNL");
entityManager.persist(employee);
}
//just trying to alter the first entry, there is one with id=1
// other CRUD methods
}
My Entity looks like this:
@Entity
@Table(name = "tbl_Employee")
public class Employee implements Serializable {
private String firstName;
private String lastName;
private String username;
private String password;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int id;
@Version
private int version;
public Employee() {}
//some getter and setter...
}
My JSF file:

thanks all for help; If anyone getting the same error than me, maybe this helps:
I used managed beans in JSF which are EJB, but I need to use CDI-Beans. As I deleted the Beans from the faces-config.xml everything works fine.
Sorry for asking this question.
