| [eclipselink-users] Eclipselink 1.1, one-to-many inside an embeddable |
|
Hello everybody! I'm using Eclipselink 1.1M1 (August 13, 2008) and failing to get a one-to-may working inside an ebmeddable - upon deployment I continue to get a NosuchElementException: Caused by: Exception [EclipseLink-28018] (Eclipse Persistence Services - 1.1 (Build SNAPSHOT - 20080813)): org.eclipse.persistence.exceptions.EntityManagerSetupException Exception Description: Predeployment of PersistenceUnit [Embed] failed. Internal Exception: java.util.NoSuchElementException at org.eclipse.persistence.exceptions.EntityManagerSetupException.predeployFailed(EntityManagerSetupException.java:210) ... 9 more Caused by: java.util.NoSuchElementException at java.util.AbstractList$Itr.next(Unknown Source) at org.eclipse.persistence.internal.jpa.metadata.MetadataDescriptor.getPrimaryKeyFieldName(MetadataDescriptor.java:679) at org.eclipse.persistence.internal.jpa.metadata.accessors.mappings.CollectionAccessor.addManyToManyRelationKeyFields(CollectionAccessor.java:116) at org.eclipse.persistence.internal.jpa.metadata.accessors.mappings.CollectionAccessor.processJoinTable(CollectionAccessor.java:314) at org.eclipse.persistence.internal.jpa.metadata.accessors.mappings.OneToManyAccessor.process(OneToManyAccessor.java:99) at org.eclipse.persistence.internal.jpa.metadata.accessors.mappings.RelationshipAccessor.processRelationship(RelationshipAccessor.java:363) at org.eclipse.persistence.internal.jpa.metadata.MetadataProject.processAccessorsWithRelationships(MetadataProject.java:643) at org.eclipse.persistence.internal.jpa.metadata.MetadataProject.process(MetadataProject.java:632) at org.eclipse.persistence.internal.jpa.metadata.MetadataProcessor.processORMMetadata(MetadataProcessor.java:452) at org.eclipse.persistence.internal.jpa.deployment.PersistenceUnitProcessor.processORMetadata(PersistenceUnitProcessor.java:303) at org.eclipse.persistence.internal.jpa.EntityManagerSetupImpl.predeploy(EntityManagerSetupImpl.java:830) Seems to me that the CollectionAccessor tries to read the embeddable's primary key field's name (asumes there is one) and fails instead of resorting to the embedding entities primary field. Am I trying to achieve something which is not supported by EclipseLink 1.1 ? BTW, I'm already using xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/orm" Thanks a lot for your help, Werner |
