PO Can't Serialize Session Beans - Warning thrown
text
Body
copied!<p>I'm running an enviroment with JSF + Primefaces + tomcat 6.0.32 in netbeans using EclipseLink (JPA 2.0).</p> <p>My application works fine, but everytime I run it, I get a lot of warnings saying that cannot Serializate my session beans, and shows me blocks like this for every session bean:</p> <pre><code>18-jul-2012 23:05:46 org.apache.catalina.session.StandardSession writeObject ADVERTENCIA: No puedo serializar atributo de sesión facturacionController para sesión 62A53325838E1E7C6EB6607B1E7965E6 java.io.NotSerializableException: org.eclipse.persistence.internal.jpa.EntityManagerFactoryImpl at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1164) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1518) ... and so on... </code></pre> <p>The thing is that my session beans already implements Serializable. So what can I do to solve this ? </p> <p>Thanks !</p> <p>---- added info 07/20/2012 ----</p> <p>The only point where I'm making a reference to EntityManager from the session bean is when I create the jpaController in the getter property, like this:</p> <pre><code>private JpaController getJpaController() { if (jpaController == null) { jpaController = new JpaController(Persistence.createEntityManagerFactory("myPersistenceUnit")); } return jpaControllerPedido; } </code></pre> <p>That is because I defined the jpaController constructor like this:</p> <pre><code>public JpaController(EntityManagerFactory emf) { this.emf = emf; } </code></pre>
