I have an java ee application with a remote business interface:
public interface RegisterRemote {
| public void createUser(User user);
| public User findUser(long id);
| }
and a stateless session bean:
@javax.ejb.Stateless
| @javax.ejb.Remote(RegisterRemote.class)
| public class RegisterBean implements RegisterRemote {
| @javax.persistence.PersistenceContext(unitName="carDatabase")
| private javax.persistence.EntityManager em;
|
| public void createUser(User user) {
| em.persist(user);
| }
|
| public User findUser(long id) {
| return em.find(User.class, id);
| }
| }
and my client looks so:
public class Client {
| static public void main(String[] args) {
| try {
| Context jndiContext = getInitialContext();
| Object ref = jndiContext.lookup("RegisterBean/remote");
| RegisterRemote dao = (RegisterRemote)
| PortableRemoteObject.narrow(ref, RegisterRemote.class);
|
| Customer customer_1 = new Customer();
| customer_1.setFirstName("Francis");
| customer_1.setLastName("Pouatcha");
| customer_1.setUsername("francis.pouatcha");
| customer_1.setPassword("franc123Poutacha");
| customer_1.setEmail("fancis.pouatcha at gmail.de");
| dao.createUser(customer_1);
|
| Customer customer_2 = (Customer) dao.findUser(1);
| System.out.println(customer_2.getFirstName());
| System.out.println(customer_2.getLastName());
| System.out.println(customer_2.getUsername());
| System.out.println(customer_2.getPassword());
| System.out.println(customer_2.getEmail());
|
| } catch ( NamingException ne ) {
| ne.printStackTrace();
| }
| }
| private static Context getInitialContext() throws NamingException {
| java.util.Properties properties = new java.util.Properties();
| properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
| properties.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
| properties.put(Context.PROVIDER_URL, "jnp://localhost:1099");
| return new javax.naming.InitialContext(properties);
| }
| }
and then when I run this client for the first time this do all things fine. But when I change the annotion of the session bean to @javax.ejb.Stateful then I get this error:
[java] Exception in thread "main" javax.ejb.EJBException: java.lang.IllegalArgumentException: Wrong target. class de.mathema.slsb.RegisterBean for public void de.mathema.slsb.RegisterBean.createUser(de.mathema.domain.User)

But when I restart the server and then run my client for the second time this work fine.
Can somebody tells me what is here the problem, because I know that jboss as is a hot-deployment server that can inspect that something have been changed.
Thanks.
