I'm trying to get three simple beans to map to each other and am getting the
following exception (v4.03SP1 EJB RFC 5):
(InvocationTargetException).....
Caused by: org.hibernate.AnnotationException: com.sms.srs.entity.Attribute
collection not yet supported: com.sms.srs.entity.AttributeNameattr
at
org.hibernate.cfg.annotations.CollectionBinder.getCollectionBinder(CollectionBinder.java:197)
at
org.hibernate.cfg.AnnotationBinder.processElementAnnotations(AnnotationBinder.java:1175)
at
org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:629)
at
org.hibernate.cfg.AnnotationConfiguration.processArtifactsOfType(AnnotationConfiguration.java:276)
The classes involved are:
| @Entity
| @Table (name="ship")
| public class Ship {
|
| public int getImo() {
| return imo;
| }
|
| public void setImo(int imo) {
| this.imo = imo;
| }
|
| @Id @GeneratedValue(strategy= GenerationType.AUTO)
| public int getId() {
| return id;
| }
|
| public void setId(int id) {
| this.id = id;
| }
|
| @CollectionOfElements
| public Collection<Attribute> getAttributes() {
| return attributes;
| }
|
| public void setAttributes(Collection<Attribute> attributes) {
| this.attributes = attributes;
| }
|
| private int imo;
| private int id;
| private Collection<Attribute> attributes;
|
|
|
| }
|
| @Entity
| @Embeddable
| @Table (name="attribute")
| public class Attribute {
|
| @Id @GeneratedValue(strategy= GenerationType.AUTO)
| public int getId() {
| return id;
| }
|
| public void setId(int id) {
| this.id = id;
| }
|
| @ManyToOne
| @JoinColumn(name = "id")
| public AttributeName getNameid() {
| return nameid;
| }
|
| public void setNameid(AttributeName nameid) {
| this.nameid = nameid;
| }
|
| public String getValue() {
| return value;
| }
|
| public void setValue(String value) {
| this.value = value;
| }
|
| @ManyToOne
| @JoinColumn(name = "id")
| public Ship getShip() {
| return ship;
| }
|
| public void setShip(Ship ship) {
| this.ship = ship;
| }
|
| public long getStartdate() {
| return startdate;
| }
|
| public void setStartdate(long startdate) {
| this.startdate = startdate;
| }
|
| public long getEnddate() {
| return enddate;
| }
|
| public void setEnddate(long enddate) {
| this.enddate = enddate;
| }
|
| private Ship ship;
| private int id;
| private AttributeName nameid;
| private String value;
| private long startdate;
| private long enddate;
|
| }
|
|
| @Entity
| @Table (name="attributename")
| public class AttributeName {
|
| @Id @GeneratedValue(strategy= GenerationType.AUTO)
| public int getId() {
| return id;
| }
|
| public void setId(int id) {
| this.id = id;
| }
|
| //Name of the attribute
| public String getName() {
| return name;
| }
|
| public void setName(String name) {
| this.name = name;
| }
|
| @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER,
mappedBy="order")
| public Attribute getAttr() {
| return attr;
| }
|
| public void setAttr(Attribute attr) {
| this.attr = attr;
| }
|
| private Attribute attr;
| private int id;
| private String name;
|
| }
|
With my persistence.xml:
| <persistence>
| <persistence-unit name="srsentity">
| <jta-data-source>java:/MySqlDS</jta-data-source>
|
| <properties>
| <property name="hibernate.dialect"
value="org.hibernate.dialect.MySQLDialect"/>
| <property name="hibernate.hbm2ddl.auto" value="update"/>
| </properties>
| </persistence-unit>
| </persistence>
|
According to the hibernate annotation documentation, if I use a collection of
elements, I should use @CollectionOfElements instead of @OneToMany.... because
the EJB spec does not support them...which I'm doing (a Ship has a collection
of Attribute)
I'd really appreciate some help here.
Thanks.
