[hibernate-issues] [Hibernate-JIRA] Resolved: (ANN-473) Unable to define unique constraints on a denormalized table (union-subclass)

Unable to define unique constraints on a denormalized table (union-subclass) ---------------------------------------------------------------------------- Key: ANN-473 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-473 Project: Hibernate Annotations Type: Bug

Components: binder Versions: 3.2.0.ga Reporter: Anthony Patricio Priority: Minor Fix For: 3.2.1 Attachments: testcase.zip very similar to that addressed in the following JIRA using hibernate annotations 3.2.0.CR2 http://opensource.atlassian.com/projects/hibernate/browse/ANN-95 The super class contains the members we are using for defining the constraint. The Super class: ---------------------------------------------------- @Entity(name="xpmComponent") @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS) public abstract class Component... @NotNull @Length(max=40) @Index(name="manufacturerPartNumber") public String getManufacturerPartNumber() { return manufacturerPartNumber; } @ManyToOne @NotNull @JoinColumn(name="manufacturerId") public Manufacturer getManufacturer() { return manufacturer; } ... The Entity w/ Unique Constraint: ---------------------------------------------------- @Entity @Name("xpmProduct") @Table(name = "xPM_Product", uniqueConstraints={@UniqueConstraint( columnNames={"manufacturerPartNumber", "manufacturerId"})}) public class PersistentProduct extends Component... The Exception which occurs upon deployment ---------------------------------------------------- java.lang.NullPointerException at org.hibernate.mapping.UniqueKey.sqlConstraintString(UniqueKey.java:20) at org.hibernate.mapping.Table.sqlCreateString(Table.java:436) at org.hibernate.cfg.Configuration.generateSchemaCreationScript(Configuration.java:779) at org.hibernate.tool.hbm2ddl.SchemaExport.<init>(SchemaExport.java:74) at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:311) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1218) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:688) at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:127) at org.jboss.ejb3.entity.PersistenceUnitDeployment.start(PersistenceUnitDeployment.java:264) at jrockit.reflect.VirtualNativeMethodInvoker.invoke(Ljava.lang.Object;[Ljava.lang.Object;)Ljava.lang.Object;(Unknown Source) at java.lang.reflect.Method.invoke(Ljava.lang.Object;[Ljava.lang.Object;I)Ljava.lang.Object;(Unknown Source) at org.jboss.ejb3.ServiceDelegateWrapper.startService(ServiceDelegateWrapper.java:102) at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:289) at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBeanSupport.java:245) at jrockit.reflect.VirtualNativeMethodInvoker.invoke(Ljava.lang.Object;[Ljava.lang.Object;)Ljava.lang.Object;(Unknown Source) at java.lang.reflect.Method.invoke(Ljava.lang.Object;[Ljava.lang.Object;I)Ljava.lang.Object;(Unknown Source) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) at org.jboss.mx.server.Invocation.invoke(Invocation.java:86) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) at org.jboss.system.ServiceController$ServiceProxy.invoke(ServiceController.java:978) at $Proxy0.start()V(Unknown Source) at org.jboss.system.ServiceController.start(ServiceController.java:417) runnable testcase attached.
