[JBoss-user] [EJB 3.0] - OneToOne problem
Hi, folks
Currently and for this case I have the following configuration, to be run under
: JBoss.4.0.3 Sp1 and the EJB3 release coming with this version of JBoss:
This is the root class
| @Entity
| @Table( name="cdmn_facturas", schema= "CellDom" )
| @Inheritance(strategy=InheritanceType.JOINED, discriminatorValue =
"OFactura", discriminatorType=DiscriminatorType.STRING)
| @DiscriminatorColumn(name="ObjClass")
| public class OFactura implements Serializable
| {
| protected String FactId;
|
| @Id(generate=GeneratorType.NONE)
| @Column( name="FactId", nullable=false )
| public String getFactId()
| {
|return FactId;
| }
|
|
|
| }
|
This is the sublcass involved in the problem
| @Entity
| @Table( name="cdmn_FacturasCompra", schema= "CellDom" )
| @Inheritance(discriminatorValue = "OFacturaCompra")
| @PrimaryKeyJoinColumn(name = "FactId", referencedColumnName="FactId" )
| public class OFacturaCompra extends OFactura implements Serializable
| {
| protected ORemision Remision;
|
|
| @OneToOne( targetEntity=ORemision.class,
| fetch=EAGER,
| cascade=CascadeType.ALL)
| @JoinColumn( name="RemId", referencedColumnName="RemId" )
| public ORemision getRemision()
| {
| return Remision;
| }
|
| public void setRemision( ORemision remision )
| {
| this.Remision = remision;
| }
|
|
| }
|
and this is the associated class involved in the problem:
| @Entity
| @Table(name="cdmn_Remisiones", schema= "CellDom")
| public class ORemision extends CEJB3Validator implements Serializable
| {
|
| private String RemId;
| private OFacturaCompra fact;
|
|
|
| @Id(generate=GeneratorType.NONE)
| @Column( name="RemId", nullable=false )
| public String getRemId()
| {
| return RemId;
| }
|
| ...
| @OneToOne(targetEntity=OFacturaCompra.class, mappedBy="Remision",
fetch=EAGER )
| public OFacturaCompra getFact()
| {
| return fact;
| }
|
| public void setFact(OFacturaCompra factNo)
| {
| this.fact = factNo;
| }
| }
|
well this configuration at deploy stage posts the following exception:

[JBoss-user] [EJB 3.0] - @OneToOne problem ...
I have two entities that I'm trying to associate using one to one. Below is
the code snippet for each:
In Relationship.java (an Entity)
| private TascForce tascForce;
|
| @OneToOne(cascade=Cascade.ALL, fetch=FetchType.EAGER)
| @JoinColumn(name="fk_tasc_tascforce")
| public TascForce getTascForce()
| {
| return(this.tascForce);
| }
|
| public void setTascForce(TascForce tascForce)
| {
| this.tascForce = tascForce;
| }
|
In TascForce.java (an Entity):
| private Relationship relationship;
|
| @OneToOne(mappedBy="tascForce", fetch=FetchType.EAGER)
| public Relationship getRelationship()
| {
| return(this.relationship);
| }
|
| public void setRelationship(Relationship relationship)
| {
| this.relationship = relationship;
| }
|
Database schemas (in MySQL 5.0):
| CREATE TABLE tasc_relationship (
| internalKey BIGINT AUTO_INCREMENT NOT NULL PRIMARY KEY,
| created DATETIME,
| createdBy BINARY(15),
| lastUpdated DATETIME,
| lastUpdatedBy BINARY(15),
| version BIGINT,
| relationshipId BINARY(15),
| loginId VARCHAR(150),
| pin BINARY(6),
| authenticationType ENUM('NATIVE', 'ACTIVE_DIRECTORY'),
| lockedOut TINYINT(1),
| fk_tasc_tascforce BIGINT
| ) TYPE = Innodb;
|
| CREATE TABLE tasc_tascforce (
| internalKey BIGINT AUTO_INCREMENT NOT NULL PRIMARY KEY,
| created DATETIME,
| createdBy BINARY(15),
| lastUpdated DATETIME,
| lastUpdatedBy BINARY(15),
| version BIGINT,
| address1 VARCHAR(100),
| address2 VARCHAR(100),
| city VARCHAR(40),
| state CHAR(2),
| deliveryArea CHAR(5),
| plusFour CHAR(4),
| fk_tasc_contact BIGINT
| ) TYPE = InnoDB;
|
I can successfully create a TascForce instance and search for a TascForce
instance (i.e. no EJB errors and the database records look good), but when I
attempt a EntityManager.merge on the TascForce object I get the following error:
