To view the discussion, visit: http://community.jboss.org/message/633610#633610 -------------------------------------------------------------- Hello, I'm evaluating JBoss 7 on some project, but I'm facing an issue : I'm using Spring to initialize my entityManager (JPA provider : Hibernate): <bean id="persistenceUnitManager" class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager">         <property name="persistenceXmlLocations">             <list>                  <value>classpath*:META-INF/persist.xml</value>              </list>         </property>         ... </bean> The persist.xml file are in jar file in WEB-INF/lib  (there are several jar with persistence unit and for instance, user.jar defines the user-pu, order.jar defines the order-pu, ...). My entities are listed in orm.xml file. for each persist.xml file, there is one orm.xml file in the same location. Now, here the full log on hibernate : DEBUG: org.hibernate.ejb.Ejb3Configuration - Processing PersistenceUnitInfo [         name: user-pu         persistence provider classname: org.hibernate.ejb.HibernatePersistence         classloader: ModuleClassLoader for Module "deployment.my-ear-1.32.0.ear.my.war:main" from Service Module Loader         Temporary classloader: org.springframework.instrument.classloading.SimpleThrowawayClassLoader@653838e4         excludeUnlistedClasses: false         JTA datasource: null         Non JTA datasource: org.jboss.jca.adapters.jdbc.WrapperDataSource@5626b468         Transaction type: RESOURCE_LOCAL         PU root URL: vfs:/content/my-ear-1.32.0.ear/my.war/WEB-INF/lib/user-1.32.0.jar/         Shared Cache Mode: UNSPECIFIED         Validation Mode: AUTO         Jar files URLs []         Managed classes names [                 my.package.user.UserEntity1  <-- defined in user.jar                 my.package.user.UserEntity2  <-- defined in user.jar                 ...                 my.package.order.OrderEntity1 <-- defined in order.jar                 ... The user-pu manage entities from user jar but also SOME (not all) other entities from other jar... The other persistence unit define no entity : DEBUG: org.hibernate.ejb.Ejb3Configuration - Processing PersistenceUnitInfo [         name: order-pu         persistence provider classname: org.hibernate.ejb.HibernatePersistence         classloader: ModuleClassLoader for Module "deployment.my-ear-1.32.0.ear.my.war:main" from Service Module Loader         Temporary classloader: org.springframework.instrument.classloading.SimpleThrowawayClassLoader@2aa20aac         excludeUnlistedClasses: false         JTA datasource: null         Non JTA datasource: org.jboss.jca.adapters.jdbc.WrapperDataSource@5626b468         Transaction type: RESOURCE_LOCAL         PU root URL: vfs:/content/my-ear-1.32.0.ear/my.war/WEB-INF/lib/order-1.6.jar/         Shared Cache Mode: UNSPECIFIED         Validation Mode: AUTO         Jar files URLs []         Managed classes names []         Mapping files names []         Properties [] So "Unknown entity" error pop on every entityManager but the one associated with user-pu. (the first pu). Is someone have already faced such issue? Is there a magic properties into JBoss to fix that?
