Answer 1

// This stored procedure returns a cursor output parameter, and has one input parameter.
@NamedStoredProcedureQuery(
    name = "ReadAddressById",
    resultClasses = Address.class,
    procedureName = "READ_ADDRESS",
    parameters = {
        @StoredProcedureParameter(mode=IN, name="P_ADDRESS_ID", type=Long.class),
        @StoredProcedureParameter(mode=REF_CURSOR, name="CUR_ADDRESS", type=void.class)
    }
)
@Entity
public class Address {
  ...
}

//Example calling a named stored procedure with a cursor output parameter
StoredProcedureQuery query = em.createNamedStoredProcedureQuery("ReadAddressById");
query.setParameter("P_ADDRESS_ID", 12345);
query.execute();
List<Address> result = (List<Address>)query.getOutputParameterValue("CUR_ADDRESS");
