Hi,
Let me first tell you about the content of my EAR archive :
VenteEnLigne.EAR :
| /META-INF
| /META-INF/application.xml
| /META-INF/MANIFEST.MF
| VenteEnLigneClient.jar
| com
| META-INF/persistence.xml
| VenteEnLigneEJB.jar
| com
| META-INF/MANIFEST.MF
| META-INF/orm.xml
| META-INF/persistence.xml
| VenteEnLigneWeb.war
| META-INF/MANIFEST.MF
| WEB-INF/web.xml
|
|
I have developped a servlet in the Web project (VenteEnLigneWeb). It calls a stateless
session bean (StockTimerService.java) that tries to execute a JPQ query with an entity
bean
developped in the EJB project.
Part of the code of StockTimerService.java is :
| ...
| @PersistenceContext(unitName="VenteEnLigneModuleEJB")
| private EntityManager em;
| ...
| List stocks = em.createQuery("from Stock").getResultList();
|
The persistent unit VenteEnLigneModuleEJB is a persistent unit that is defined inside
VenteEnLigneEJB.jar/META-INF/persistence.xml.
Its transaction type is JTA.
I get the following errors :
|

What is wrong ?
How does JBoss call the various persistence.xml files it encounters in an archive with
several projects ?
Is it something with the transaction type : JTA / RESOURCE_LOCAL ?
Thanks in advance for helping.
