What is interesting to me is that I have 7 entities in my project. All of them
work fine, except that one. Here is the source for all the beans:
1. Application and Organisation have long for primary key
| @Entity
| @Local
| @Table(name = "application")
| public class Application implements Serializable{
| private long id;
|
| private String name;
|
| private Collection<Version> versions;
|
| public Application() {
| }
|
| public Application(String name) {
| this.name = name;
| }
|
| @Id
| @GeneratedValue(strategy = GenerationType.AUTO)
| public long getId() {
| return id;
| }
|
| public void setId(long id) {
| this.id = id;
| }
|
| @Column(name="name")
| public String getName() {
| return name;
| }
|
| public void setName(String name) {
| this.name = name;
| }
|
| @OneToMany
| public Collection<Version> getVersions() {
| return versions;
| }
|
| public void setVersions(Collection<Version> versions) {
| this.versions = versions;
| }
| }
|
| @Entity
| @Local
| @Table(name = "organisation")
| public class Organisation implements Serializable {
| long id;
|
| String name;
|
| public Organisation() {
| }
|
| public Organisation(String name, long cityId) {
| this.name = name;
| }
|
| @Id
| @GeneratedValue(strategy = GenerationType.AUTO)
| public long getId() {
| return id;
| }
|
| public void setId(long id) {
| this.id = id;
| }
|
| @Column(name = "name")
| public String getName() {
| return name;
| }
|
| public void setName(String name) {
| this.name = name;
| }
|
| }
|
2. Version entity has a PK class with two fields: versionMark and foreign key
from Application
@Entity
| @Local
| @Table(name = "version")
| public class Version implements Serializable {
|
| String versionMark;
|
| Application application;
|
| VersionPK versionPK;
|
| Collection<Edition> editions;
|
| @EmbeddedId
| @AttributeOverrides( {
| @AttributeOverride(name = "versionMark", column =
@Column(name = "versionMark")),
| @AttributeOverride(name = "applicationId", column =
@Column(name = "applicationId")) })
| public VersionPK getVersionPK() {
| return versionPK;
| }
|
| public void setVersionPK(VersionPK versionPK) {
| this.versionPK = versionPK;
| }
|
| @Column(name = "versionMark", updatable = false, insertable = false)
| public String getVersionMark() {
| return versionMark;
| }
|
| public void setVersionMark(String versionMark) {
| this.versionMark = versionMark;
| }
|
| @ManyToOne
| @JoinColumn(name = "applicationId", insertable = false, updatable =
false)
| public Application getApplication() {
| return application;
| }
|
| public void setApplication(Application application) {
| this.application = application;
| }
|
| @OneToMany(cascade = CascadeType.ALL, mappedBy = "version")
| public Collection<Edition> getEditions() {
| return editions;
| }
|
| public void setEditions(Collection<Edition> editions) {
| this.editions = editions;
| }
| }
|
and PK:
| @Embeddable
| public class VersionPK implements Serializable {
|
| private String versionMark;
|
| private long applicationId;
|
| public VersionPK() {
| }
|
| public VersionPK(String versionMark, long applicationId) {
| this.versionMark = versionMark;
| this.applicationId = applicationId;
| }
|
| public long getApplicationId() {
| return applicationId;
| }
|
| public void setApplicationId(long applicationId) {
| this.applicationId = applicationId;
| }
|
| public String getVersionMark() {
| return versionMark;
| }
|
| public void setVersionMark(String versionMark) {
| this.versionMark = versionMark;
| }
|
| public int hashCode() {
| return (int) versionMark.hashCode()
| + (int) (new Long(applicationId)).hashCode();
| }
|
| public boolean equals(Object obj) {
| if (obj == this)
| return true;
| if (!(obj instanceof VersionPK))
| return false;
| if (obj == null)
| return false;
| VersionPK pk = (VersionPK) obj;
| return pk.versionMark.equals(versionMark)
| && pk.applicationId == applicationId;
| }
|
| }
|
3. Finally, there is Edition entity with primary key of foreign keys from the
Version and from the Organisation:
@Entity
| @Local
| @Table(name = "edition")
| public class Edition implements Serializable {
| private EditionPK editionPK;
|
| private Organisation organisation;
|
| private Version version;
|
| @EmbeddedId
| @AttributeOverrides( {
| @AttributeOverride(name = "organisationId", column =
@Column(name = "organisationId")),
| @AttributeOverride(name = "versionMark", column =
@Column(name = "versionMark")),
| @AttributeOverride(name = "applicationId", column =
@Column(name = "applicationId")) })
| public EditionPK getEditionPK() {
| return editionPK;
| }
|
| public void setEditionPK(EditionPK editionPK) {
| this.editionPK = editionPK;
| }
|
| @ManyToOne(targetEntity = Organisation.class, cascade =
CascadeType.ALL, fetch = FetchType.EAGER, optional = false)
| @JoinColumn(name = "organisationId", insertable = false, updatable =
false)
| public Organisation getOrganisation() {
| return organisation;
| }
|
| public void setOrganisation(Organisation organisation) {
| this.organisation = organisation;
| }
|
| @ManyToOne
| @JoinColumns( {
| @JoinColumn(name = "versionMark", insertable = false,
updatable = false),
| @JoinColumn(name = "applicationId", insertable = false,
updatable = false) })
| public Version getVersion() {
| return version;
| }
|
| public void setVersion(Version version) {
| this.version = version;
| }
|
| public Edition(Organisation organisation, Version version) {
| this.organisation = organisation;
| this.version = version;
| }
|
| public Edition() {
| }
|
|
| }
|
and PK:
@Embeddable
| public class EditionPK implements Serializable {
|
| String versionMark;
|
| long applicationId;
|
| long organisationId;
|
| public EditionPK() {
| }
|
| public EditionPK(String versionMark, long applicationId, long
organisationId) {
| this.versionMark = versionMark;
| this.applicationId = applicationId;
| this.organisationId = organisationId;
| }
|
| public long getApplicationId() {
| return applicationId;
| }
|
| public void setApplicationId(long applicationId) {
| this.applicationId = applicationId;
| }
|
| public String getVersionMark() {
| return versionMark;
| }
|
| public void setVersionMark(String versionMark) {
| this.versionMark = versionMark;
| }
|
| public long getOrganisationId() {
| return organisationId;
| }
|
| public void setOrganisationId(long organisationId) {
| this.organisationId = organisationId;
| }
|
| public int hashCode() {
| return (int) versionMark.hashCode()
| + (int) (new Long(applicationId)).hashCode()
| + (int) (new Long(organisationId)).hashCode();
| }
|
| public boolean equals(Object obj) {
| if (obj == this)
| return true;
| if (!(obj instanceof VersionPK))
| return false;
| if (obj == null)
| return false;
| EditionPK pk = (EditionPK) obj;
| return pk.getVersionMark().equals(versionMark)
| && pk.getApplicationId()== applicationId
| && pk.getOrganisationId() == organisationId;
| }
| }
|
Everything works fine, until I try to work with Edition. Every query works fine
for every other bean. I'm using facade pattern. I get other entities (as
POJOs,of course) on the client side, but Edition breaks, even if I don't send
it. I have another bean that is @ManyToOne with Edition and when I try to do
query within facade and to set it to that other bean it breaks within facade
(without anything sent to client).
Can anyone tell me what's wrong?
