[jboss-user] [JBoss Seam] - Single EntityManager

[yoav200]

Hello,

i have a webapp build with seam,ejb3 and jsf.
in the application i have several different action to manipulate the DB.
not only from the webclient (browser) but from web services.

my broblem is that if a web service changed some thing it doesn't reflect on the web (the DB has chaged).

i have printed the id of the entetyManager (hashcode) and i'm getting a different one for each request.
my entityManager is injected using seam.
this is a big issue for me since i have wrong data in my web.

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);
  | 	}
  | ......
  |
