[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - problem when I want to persist data
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;
| }
|
| }
|
and my page :
