@Stateless
@TransactionManagement(TransactionManagementType.BEAN)
@Name("monbean")
public class MyFirstBean implements MonInterface{
@Logger
Log log;
@PersistenceContext
private EntityManager em;
public MyFirstBean () {
}
public void start(Message msg) { // methode de mon interface
try {
em.getTransaction().begin(); // erreur a ce niveau
// ...mon traitement
} catch (Exception e) {
log.error("Ooops! Exception", e);
} finally {
jbpmContext.close();
em.getTransaction().commit();
}
}
} |
et finalement mon interface est la suivante:
Code:
1

import javax.jms.Message;
public interface MonInterface{
public void start(Message msg);
} |
je ne comprends pas pourquoi j'ai cet erreur?
Merci
