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.
