Web Page Having Trouble Connecting to EJB 3.0 Enity

[kurzweil4]

I have an application with a Model and a View project. The bean in the View project is having trouble finding the EJB Enity in the Model project. The binding DepartmentsBean.departments is failing with this error:

javax.el.ELException: javax.faces.el.EvaluationException: javax.el.ELException: Error reading 'departments' on type ice.data.table.view.DepartmentsBean

I had the EXACT same error when I was deploying to OC4J, but the problem was that my Model project was not deployed as an EJB Jar. That is not the problem in this case since I am now using en EJB Jar.

Also, I have tested my DB connection with a plain JSP manually querying a table in the DB, so I know my connection configuration is good.

This is my persistence.xml:

<?xml version="1.0" encoding="windows-1252" ?>
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
 version="1.0" xmlns="http://java.sun.com/xml/ns/persistence">
 <persistence-unit name="Model">
 <jta-data-source>java:/hr</jta-data-source>
 <class>ice.data.table.model.Departments</class>
 <class>ice.data.table.model.DepPublicFacade</class>
 <class>ice.data.table.model.DepPublicFacadeLocal</class>
 <class>ice.data.table.model.DepPublicFacadeBean</class>
 </persistence-unit>
</persistence>

This is my entity:

@Entity
@NamedQuery( name = "Departments.findAll",
 query = "select o from Departments o" )
public class Departments implements Serializable
{
 @Id
 @Column( name="DEPARTMENT_ID", nullable = false )
 private Long departmentId;
 @Column( name="DEPARTMENT_NAME", nullable = false )
 private String departmentName;
 @Column( name="LOCATION_ID" )
 private Long locationId;
 @Column( name="MANAGER_ID" )
 private Long managerId;

 public Departments()
 {
 }

 public Long getDepartmentId()
 {
 return departmentId;
 }

 public void setDepartmentId( Long departmentId )
 {
 this.departmentId = departmentId;
 }

 public String getDepartmentName()
 {
 return departmentName;
 }

 public void setDepartmentName( String departmentName )
 {
 this.departmentName = departmentName;
 }

 public Long getLocationId()
 {
 return locationId;
 }

 public void setLocationId( Long locationId )
 {
 this.locationId = locationId;
 }

 public Long getManagerId()
 {
 return managerId;
 }

 public void setManagerId( Long managerId )
 {
 this.managerId = managerId;
 }
}

This is my facade:

@Stateless( name="DepPublicFacade" )
public class DepPublicFacadeBean implements DepPublicFacade, DepPublicFacadeLocal
{
 @PersistenceContext( unitName="Model" )
 private EntityManager em;

 public DepPublicFacadeBean()
 {
 }

 public Object mergeEntity( Object entity )
 {
 return em.merge(entity);
 }

 public Object persistEntity( Object entity )
 {
 em.persist(entity);
 return entity;
 }

 /** <code>select o from Departments o</code> */
 public List<Departments> queryDepartmentsFindAll()
 {
 return em.createNamedQuery("Departments.findAll").getResultList();
 }

 public void removeDepartments( Departments departments )
 {
 departments = em.find(Departments.class, departments.getDepartmentId());
 em.remove(departments);
 }
}

This is my bean from the View project:

public class DepartmentsBean
{
 private DepPublicFacade model;

 public DepartmentsBean()
 {
 try
 {
 final Context context = getInitialContext();
 model = (DepPublicFacade)context.lookup("DepPublicFacade");
 }
 catch (Exception ex)
 {
 ex.printStackTrace();
 }
 }

 public List getDepartments()
 {
 return model.queryDepartmentsFindAll();
 }

 private static Context getInitialContext() throws NamingException
 {
 // Get InitialContext for Embedded OC4J
 // The embedded server must be running for lookups to succeed.
 return new InitialContext();
 }
}

Any help or pointers to information would be appreciated. I am at a loss here.

Thanks,
