Hi, I have the same opinion like you know. I must change the PK in DB to get it run. I have already changed it and works fine!

First, Sorry for the Route/Road mismatch! In fact is it Road, i checked it before. The structure: Location ___|___Road ___ | IATA PK---> ORIGINPK +FK spacee ---> DESTINATIONPK + FK So IATA is a String of an Location/Place and Road has a StartPoint (ORIGIN) and an EndPoint (DESTINATION). So Road has a double relation with Location. The idea behind this structure, in Java, is to know from one Road, for example, which the Details of the Origin/Destination from type Location are without using SQL and just work with Java classes.

Hi, the problem is that i don't have the permission to make changes on the DB because it's a LIVE/Production DB. So problems with releases/changes and so on. I tried to access now my attributs via @NamedQuery like this: SELECT r.roadPK.origin.iata,r.roadPK.destination.iata, r.availabilityMethod FROM Road r but there I got a compiler error: Caused by: org.hibernate.HibernateException: Errors in named queries: Road.listAll | at org.hibernate.impl.SessionFactoryImpl.(SessionFactoryImpl.java:397) | at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1327) | at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:867) | at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:669) | ... 75 more By testing with SELECT r.roadPK.origin, r.roadPK.destination,r.availabilityMethod FROM Route r i didn't get any error but also any output. lol Like i told it before, with SELECT r.availabilityMethod FROM Route r is no problem! So logically I can access my attributs via r.roadPK.origin.iata but I get there the error! So I think that my mapping is wrong.

First, thanks for the fast answer. I also tried two to make the FechType to lazy but that didn't change anything. But for the first point with the ID. Can you explain me more in detail what do you mean. For example, where to set the ID? Do you want to set an new phyiscal ID in the Tables and to work with it or do you want to change the ID type in ROAD? thx View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4227166#4227166 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4227166 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

[jboss-user] [EJB 3.0] - EJB3: org.hibernate.type.SerializationException: could not d
Hi everybody,
I would get an Output of an Table Road (Oracle Database) via EntityManager and
Web Services. I got the following error :
org.hibernate.type.SerializationException: could not deserialize
Eclipe3.4.1/Glassfish V2.1/SoapUI 2.5 (for testing)
Enviroment:
Class : Location
IATA(PK)
Class : Road
Origin(PK)(FK of IATA)
Destination (PK)(FK of IATA)
To manage the composite ID I generated a class RoadPK which is below:
import java.io.Serializable;
| import javax.persistence.Embeddable;
| @Embeddable
| public class RoadPK implements Serializable {
|
| /**
| * Variable of type Location
| */
| private Location origin = null;
|
| private Location destination = null;
| ..(Getter/Setter).
|
Class Road have the attributs(the composite ID).
I locate the Problem here in the @nameQuery. I can show all availability
methods when I write SELECT r.availabilityMethod FROM ROADS r.
But I can't access origin and destination by SELECT r.origin.iata FROM ROADS r
. So my Question is:
Is my mapping wrong or is there no posssibility to work with Type classes for
attributes in composite IDs in EJB3?
@Entity
| @NamedQuery(
| name = "ROADS.listAll",
| query = "SELECT r FROM ROADS r")/*
|
| @Table(name="ROADS")
| public class ROADS implements Serializable {
|
| private RoadPK roadPK = null;
| private String availabilityMethod = null;
|
| @EmbeddedId
| public RoadPK getRoadPK() {
| return roadPK ;
| }
|
| public void setRoadPK(RoadPK roadPK ) {
| this.roadPK = roadPK ;
|}
|@Column(name="AVAILABILITY_METHOD")
| public String getAvailabilityMethod() {
| return availabilityMethod;
| }
|
|
| public void setAvailabilityMethod(final String availabilityMethodParam)
{
| this.availabilityMethod = availabilityMethodParam;
| }
|
|
| }
Class Location:
@Entity
| @Table(name = "LOCATIONS")
| public class Location implements Serializable {
|
| private String iata = null;
|
| /**
| * The Roads
| */
| private Set roadsorigin;
|
| private Set roadsdestination;
|
| @Id
| @Column(name = "IATA")
| public String getIata() {
| return iata;
| }
| //...
| @OneToMany(mappedBy = "roadPK.origin", fetch = FetchType.EAGER, cascade
= CascadeType.ALL)
| public Set getRoadsorigin() {
|return roadsorigin;
| }
|
| public void setRoadsorigin(Set roadsorigin) {
| this.roadsorigin= roadsorigin;
| }
|
| @OneToMany(mappedBy = "roadPK.destination", fetch = FetchType.EAGER,
cascade = CascadeType.ALL)
| public Set getRoadsdestination() {
| return roadsdestination;
| }
|
| public void setRoadsdestination(Set roadsdestination) {
| this.roadsdestination = roadsdestination;
| }
| }
The class RoadDAO offers the WebServices:
@WebService
| @Stateless(name="RoadDAO")
| public class RoadDAOimplements Serializable {
|
| @PersistenceContext(name="ResourceDS")
| private EntityManager em;
| //
| @SuppressWarnings("unchecked")
| @WebMethod
| @WebResult(name="RoadsList")
| public final List < Road> listRoad() {
| return em.createNamedQuery("Road.listAll").getResultList();
| }
| //
| }
Thanks for reading
