      Hi !!

      I want to persist data in my database. However I have an error :

      Exception during request processing: javax.servlet.ServletException: /abonnement_contact.xhtml @17,68 value="#{contact.firstName}": Target Unreachable, identifier 'contact' resolved to null
      


      Here is my ContactManager :
      @Stateful
      @Name("ContactManager")
      @Scope(SESSION)
      public class ContactManager implements com.pingwy.web.front.ContactManagerLocal, Serializable{
      
      
       @In
       private EntityManager em;
      
       @In (create = true, required = true) @Out
       private Contact contact;
      
      
       @In @Out (required = false)
       Contact currentContact;
      
      
       public String updateContact(){
      
      
       em.merge(currentContact);
      
       return null;
      
       }
      
      
       public String removeContact (){
      
      
       System.out.println("contact bientot supprimé");
       em.remove(currentContact);
       return null;
       }
      
      
      
       public String createContact(Contact c){
       contact = c;
       em.persist(contact);
       return null;
      
      
       }
      
      
      
       @Remove @Destroy
       public void destroy(){
       }
      
       public Contact getContact() {
       return contact;
       }
      
       public void setContact(Contact contact) {
       this.contact = contact;
       }
      
      }
