Named query does not support entity attribute with generic type --------------------------------------------------------------- Key: EJB-372 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-372 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.3.2.GA Environment: hibernate-3.3.0.CR1, hibernate-annotations-3.4.0.CR1 Reporter: louie Attachments: test-case.zip We are using the generic to define a template for our entity. For example, we have the following abstract template class: @MappedSuperclass public abstract class AbstractIdentifier<T> { @Id @SequenceGenerator(name = "AbstractIdentifier", sequenceName = "identifier_id") @GeneratedValue(generator="AbstractIdentifier") private int id; @ManyToOne(optional=false) private T entity; .... } We have the following concrete class: @Entity @AssociationOverride(name="entity", joinColumns=@JoinColumn(name="myEntity")) public class Identifier extends AbstractIdentifier<MyEntity> { public MyEntity getMyEntity () { return super.getEntity(); } public void setMyEntity (final MyEntity myEntity) { super.setEntity(myEntity); } } If we defined a named query, such as: @NamedQueries( { @NamedQuery(name = "myquery", query = "select idf.myEntity from Identifier idf where idf.identifier = :identifier")}) Then, at runtime, we got the following error message: run: [java] Executing 'C:\Program Files\Java\jdk1.6.0_05\jre\bin\java.exe' with arguments: [java] '-classpath' [java] 'C:\workspaces\test-case\test-case\lib\antlr-2.7.6.jar;C:\workspaces\test-case\test-case \lib\cglib.jar;C:\workspaces\test-case\test-case\lib\commons-collections-3.1.jar;C:\workspaces\test- case\test-case\lib\commons-logging-1.1.1.jar;C:\workspaces\test-case\test-case\lib\dom4j-1.6.1.jar;C :\workspaces\test-case\test-case\lib\ejb3-persistence.jar;C:\workspaces\test-case\test-case\lib\free marker.jar;C:\workspaces\test-case\test-case\lib\hibernate-annotations.jar;C:\workspaces\test-case\t est-case\lib\hibernate-commons-annotations.jar;C:\workspaces\test-case\test-case\lib\hibernate-entit ymanager.jar;C:\workspaces\test-case\test-case\lib\hibernate-tools.jar;C:\workspaces\test-case\test- case\lib\hibernate3.jar;C:\workspaces\test-case\test-case\lib\hsqldb.jar;C:\workspaces\test-case\tes t-case\lib\javassist-3.6.0.GA.jar;C:\workspaces\test-case\test-case\lib\jboss-archive-browsing.jar;C :\workspaces\test-case\test-case\lib\jta.jar;C:\workspaces\test-case\test-case\lib\log4j-1.2.15.jar; C:\workspaces\test-case\test-case\lib\ojdbc14.jar;C:\workspaces\test-case\test-case\lib\persistence- api-1.0.jar;C:\workspaces\test-case\test-case\lib\persistence-api.jar;C:\workspaces\test-case\test-c ase\lib\slf4j-api-1.4.2.jar;C:\workspaces\test-case\test-case\lib\slf4j-log4j12-1.5.2.jar;C:\workspa ces\test-case\test-case\bin' [java] 'Tester' [java] [java] The ' characters around the executable and arguments are [java] not part of the command.
