[EJB 3.0] - Re: Deployment problems - persistence unit could not be crea
by dgdwinte
I'm sorry, I've pushed too fast on the button "submit" making an unclear post:
the main problem is thus:
| 2007-07-15 15:23:08,656 INFO [org.hibernate.ejb.Ejb3Configuration] found EJB3 Entity bean: be.erpsystem.texaco.articles.Article
| 2007-07-15 15:23:08,671 WARN [org.hibernate.ejb.Ejb3Configuration] Persistence provider caller does not implements the EJB3 spec correctly. PersistenceUnitInfo.getNewTempClassLoader() is null.
| 2007-07-15 15:23:08,671 DEBUG [org.jboss.ejb3.ServiceDelegateWrapper] Starting failed persistence.units:ear=texaco_deploy-1.0-SNAPSHOT.ear,jar=texaco_model-1.0-SNAPSHOT.ejb3.jar,unitName=texaco
| javax.persistence.PersistenceException: [PersistenceUnit: texaco] class or package not found
| at org.hibernate.ejb.Ejb3Configuration.addNamedAnnotatedClasses(Ejb3Configuration.java:1089)
|
The persistence-unit defined in persistence.xml cannot be found. The
following annotation in my session-bean causes the problem:
| import javax.persistence.EntityManager;
| import javax.persistence.PersistenceContext;
|
| @Stateless
| public class ArticleManager implements ArticleManagerRemote, ArticleManagerLocal {
| @PersistenceContext (unitName="texaco") EntityManager em;
|
causing the problem.
The persistence.xml-file is read correctly and the binding to the (MySQL) datasource works fine. The persistence.xml looks as follows:
| <persistence>
| <persistence-unit name="texaco">
| <jta-data-source>java:TexacoDS</jta-data-source>
| <class>be.erpsystem.texaco.Article</class>
| </persistence-unit>
| </persistence>
|
Thanks again and sorry for the bad post.
Davy.
