@ElementCollection @Lob List<byte[]> fails ------------------------------------------ Key: HHH-6295 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6295 Project: Hibernate Core Issue Type: Bug Components: annotations Affects Versions: 3.6.4 Reporter: Aleksei Valikov I am trying to map a List of {{byte[]}} as a @Lob @ElementCollection with no success. Below are test cases. Variant 1 (without targetClass): {code} @Entity public class G { private String id; @Id public String getId() { return id; } public void setId(String id) { this.id = id; } private List<byte[]> bytes; @ElementCollection @Lob public List<byte[]> getBytes() { return bytes; } public void setBytes(List<byte[]> bytes) { this.bytes = bytes; } } {code} Stack trace: {code}javax.persistence.PersistenceException: [PersistenceUnit: org.jvnet.hyperjaxb3.hibernate.tests.hhh] Unable to configure EntityManagerFactory at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:378) at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:56) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:48) at org.jvnet.hyperjaxb3.hibernate.tests.hhh.EntityManagerFactoryTest.entityManagerFactoryCreated(EntityManagerFactoryTest.java:22) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:76) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:49) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) Caused by: org.hibernate.AnnotationException: Collection has neither generic type or OneToMany.targetEntity() defined: org.jvnet.hyperjaxb3.hibernate.tests.hhh.G.bytes at org.hibernate.cfg.annotations.CollectionBinder.getCollectionType(CollectionBinder.java:621) at org.hibernate.cfg.annotations.CollectionBinder.bind(CollectionBinder.java:509) at org.hibernate.cfg.AnnotationBinder.processElementAnnotations(AnnotationBinder.java:1979) at org.hibernate.cfg.AnnotationBinder.processIdPropertiesIfNotAlready(AnnotationBinder.java:796) at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:707) at org.hibernate.cfg.Configuration$MetadataSourceQueue.processAnnotatedClassesQueue(Configuration.java:4035) at org.hibernate.cfg.Configuration$MetadataSourceQueue.processMetadata(Configuration.java:3989) at org.hibernate.cfg.Configuration.secondPassCompile(Configuration.java:1398) at org.hibernate.cfg.Configuration.buildMappings(Configuration.java:1375) at org.hibernate.ejb.Ejb3Configuration.buildMappings(Ejb3Configuration.java:1519) at org.hibernate.ejb.EventListenerConfigurator.configure(EventListenerConfigurator.java:193) at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:1100) at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:282) at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:366) ... 25 more {code} Variant 2 (with targetClass): {code} @Entity public class G { private String id; @Id public String getId() { return id; } public void setId(String id) { this.id = id; } private List<byte[]> bytes; @ElementCollection(targetClass=byte[].class) @Lob public List<byte[]> getBytes() { return bytes; } public void setBytes(List<byte[]> bytes) { this.bytes = bytes; } }{code} Stack trace: {code} org.hibernate.annotations.common.AssertionFailure: Fail to process type argument in a generic declaration.
