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"?> | <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: | .... | @Name("genericDao") | public abstract class GenericDaoImpl<T> implements GenericDao<T> { | | @In(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 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4065287#...
