EJB 3.0 Locking (entity not in the persistence context)
hi all,

@Remote(RemoteInterface.class)
class RemoteInterfaceBean implements RemoteInterface
{
@PersistenceContext(unitName = "CustomerCareOracle")
private EntityManager oracleManager;
public MySomeEntityObject object;
@EJB
MyLocalInterface inter;
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public void fillMyObject(someparameters .... )
{
// filling MySomeEntityObject object
}
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public void commitMyObject()
{
inter.AnotherOperatOnObject(object);
oracleManager.persist(object);
}
}
2. My Local Interface
public @Stateless
@Local(MyLocalInterface.class)
class MyLocalInterfaceBean implements MyLocalInterface
{
@PersistenceContext(unitName = "CustomerCareOracle")
private EntityManager oracleManager;
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public void AnotherOperatOnObject(MySomeEntityObject object)
{
oracleManager.lock(object,LockModeType.READ); // <= Here I Got An Error
// do some operation and is succsess, It's very good ;)
}
