Hello,
i have a webapp build with seam, ejb3 and JSF on jboss.
i deploy it as ear archive that contain a war and some jar files.
few jars has persistence entities (all on same DB).
what i did is put persistence.xml in all jars that has entities, in all
persistence i call the same factory.
in the components.xml (seam) that is in the war i have declared an
entityManager.
the idea is to have one entity manager for all persistence entities.
when i deploy to jboss i see that hibernate recognize all my entities and when
i debug my DAO object (that the entityManager inject into) the em is NOT null
but for some reason iget an exception that one of my entity is Unknown [javax
.ejb.EJBTransactionRolledbackException: java.lang.IllegalArgumentException  :
Unknown entity: com.mobimate.account.domain.Account]
here is my persistence.xml:
| <?xml version="1.0" encoding="UTF-8 (See http://UTF-8.ora-code.com)"?>
| <persistence xmlns="http://java.sun.com/xml/ns/persistence"
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0"
| xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun
.com/xml/ns/persistence/persistence_1_0.xsd">
|
| <persistence-unit name="account">
| <jta-data-source>java:/jdbc/wml</jta-data-source>
| <properties>
| <property name="jboss.entity.manager.factory.jndi.name"
| value="java:/wmlEntityManagerFactory" />
| <property name="hibernate.dialect"
| value="org.hibernate.dialect.MySQLInnoDBDialect " />
| </properties>
| </persistence-unit>
|
| </persistence>
|
and here is my components.xml:
| ....
| <component name="wmlEntityManager"
| class="org.jboss.seam.core.ManagedPersistenceContext" auto-create="true">
| <property name="persistenceUnitJndiName">java:/wmlEntityManagerFactory<
/property>
| </component>
| .....
|
and the DAO:
| ....
| @(protected)("genericDao")
| public abstract class GenericDaoImpl<T> implements GenericDao<T> {
|
| @(protected)(value="wmlEntityManager")
| EntityManager em;
|
| public T get(Serializable id) {
| return em.find(getPersistentClass(), id);
| }
| ......
|
i get the exception in the find.
what am i doing wrong ?
thanks
