NamedQuery not found Hibernate4 Seam 2.2 JPA 2.0 and Jboss eap 6 - jpa

Question

I am receiving the Named Query not found error message on JBOSS EAP 6.3 server. I am using Hibernate4 Seam 2.2 JPA 2.0 and Jboss eap 6 in my application.
Caused by: java.lang.IllegalArgumentException: Named query not found: findOfficerByEmpIDFetchAssigners

My Entity class,
#Entity
#Table(name="OFFICER")
#NamedQueries({
#NamedQuery(name="findOfficerByEmployeeId",
query="from Officer where upper(employeeId)=upper(:id) order by employeeId"),
#NamedQuery(name="findOfficerByEmpIDFetchAssigners",
query="from Officer o left join fetch o.assigners ass where upper(o.employeeId) = :id")
})
public class Officer implements java.io.Serializable {
And Here is my Stateless bean class I am calling the NamedQuery,
#Stateless
#Name("batchProcessor")
#AutoCreate
#TransactionManagement(TransactionManagementType.BEAN)
public class BatchProcessorBean implements BatchProcessor, Serializable {
private static final long serialVersionUID = 395715959808111918L;
#SuppressWarnings("seam-unresolved-variable")
#In(value = "entityManager")
private EntityManager em;
public Officer getLoggedInUser(String employeeID) {
UserTransaction instance = Transaction.instance();
List<Officer> list = em.createNamedQuery("findOfficerByEmpIDFetchAssigners").setParameter("id", employeeID).getResultList();
I placed the persistence.xml in the under ejb/resources/META-INF folder. I have tried the previous posts regarding the NamedQuery Not found issue. That is not fixing my issue
Please help me to figure out the issue. Thanks

I have resolved the issue. I have added the the following class tag in persistence.xml to resolve the issue,
<class>com.wachovia.apps.amaster.orm.Officer</class>
The order of the tags are important in persistence.xml. In my case, this class tag must be added before the <properties> tag and after the <jta-data-source> tag.
