Hi ,
thanks for your response. I have gone through your links but there is no clear indication. I put the environments and the code
pls. make a review if it is right but I am getting null pointer exception.
Environment:
Netbeans 7.2 , Glassfish 3.1, EclipseLink, version: Eclipse Persistence Services - 2.4.1.v20121003-ad44345
EJB:: Account.java
-----------------------------
@Entity
@Multitenant(MultitenantType.TABLE_PER_TENANT)
@TenantTableDiscriminator(type=TenantTableDiscriminatorType.SCHEMA, contextProperty="eclipselink.mytenant1")
@Table(name = "ACCOUNT")
@XmlRootElement
@NamedQueries({
})
..........................
...................
Stateless:: AccountServices.java
--------------------------------------
public EntityManager getEMF() {
if (em == null) {
// Non shared EMF
System.out.println("getEMF()-> emf is null");
HashMap properties = new HashMap();
properties.put(PersistenceUnitProperties.TRANSACTION_TYPE, PersistenceUnitTransactionType.JTA.name());
properties.put(PersistenceUnitProperties.MULTITENANT_SHARED_EMF, "false");
properties.put(PersistenceUnitProperties.SESSION_NAME, "non-shared-emf-for-mytenant1");
properties.put(PersistenceUnitProperties.MULTITENANT_PROPERTY_DEFAULT, "mytenant1");
em = Persistence.createEntityManagerFactory("tenantproj-ejbPU").createEntityManager(properties);
}
return em;
}
}
Persistence.xml

The null-pointer seems like the descriptor was not initialized.
It could be an issue with passing the properties to the createEntityManager, try removing this.
Also please try the latest patch, and log a bug if you still get the error, a null-pointer exception should never occur.
