Hibernate dose not support the single-table inheritance strategy for relational entities ---------------------------------------------------------------------------------------- Key: EJB-371 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-371 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.4.0.CR1 Environment: hibernate-annotations-3.4.0.CR1, hibernate-conmmons-annotations-3.1.0.CR1,hibernate-tools-3.2.0.GA Reporter: louie Attachments: test-case.zip Hibernate EJB configuration failed in the case of single-table inheritance strategy for relational entities. Here is the use case: @Entity public class User { @Id @SequenceGenerator(name = "user", sequenceName = "user_id") @GeneratedValue(generator = "user") private int id; private String name; @OneToMany(mappedBy = "user") private List<ExcludedGroupUser> excludedUsers; @OneToMany(mappedBy = "user") private List<IncludedGroupUser> includedUsers; ... } @Entity public class Group { @Id @SequenceGenerator(name = "group", sequenceName = "group_id") @GeneratedValue(generator = "group") private int id; private String name; @ManyToOne(fetch = FetchType.EAGER) private Group underlying; /** list of user belong to underlying group, but not belongs to this group */ @OneToMany(mappedBy = "group") private List<ExcludedGroupUser> excludedUsers; /** list of user belong to this group **/ @OneToMany(mappedBy = "group") private List<IncludedGroupUser> includedUsers; ... } The main relational entity: @Entity @Inheritance(strategy=InheritanceType.SINGLE_TABLE) @DiscriminatorColumn(name="groupType",discriminatorType=DiscriminatorType.STRING, length=1) public class GroupUser { @Id @SequenceGenerator(name = "groupUser", sequenceName = "groupUser_id") @GeneratedValue(generator = "groupUser") private int id; @ManyToOne private Group group; @ManyToOne private User user; ... } The subclasses: @Entity @DiscriminatorValue("I") public class IncludedGroupUser extends GroupUser{ } and @Entity @DiscriminatorValue("E") public class ExcludedGroupUser extends GroupUser { } The build output error message: C:\workspaces\test-case\test-case>ant -verbose Apache Ant version 1.6.5 compiled on June 2 2005 Buildfile: build.xml Detected Java version: 1.5 in: C:\Program Files\Java\jdk1.6.0_05\jre Detected OS: Windows XP parsing buildfile C:\workspaces\test-case\test-case\build.xml with URI = file:///C:/workspaces/test- case/test-case/build.xml Project base dir set to: C:\workspaces\test-case\test-case Build sequence for target(s) `compile' is [clean, copy-resources, compile] Complete build sequence is [clean, copy-resources, compile, ] clean: [delete] Deleting directory C:\workspaces\test-case\test-case\bin [delete] Deleting C:\workspaces\test-case\test-case\bin\META-INF\persistence.xml [delete] Deleting directory C:\workspaces\test-case\test-case\bin\META-INF [delete] Deleting C:\workspaces\test-case\test-case\bin\notWorking\ExcludedGroupUser.class [delete] Deleting C:\workspaces\test-case\test-case\bin\notWorking\Group.class [delete] Deleting C:\workspaces\test-case\test-case\bin\notWorking\GroupUser.class [delete] Deleting C:\workspaces\test-case\test-case\bin\notWorking\IncludedGroupUser.class [delete] Deleting C:\workspaces\test-case\test-case\bin\notWorking\User.class [delete] Deleting directory C:\workspaces\test-case\test-case\bin\notWorking [delete] Deleting C:\workspaces\test-case\test-case\bin\working\Employee.class [delete] Deleting C:\workspaces\test-case\test-case\bin\working\FullTimeEmployee.class [delete] Deleting C:\workspaces\test-case\test-case\bin\working\PartTimeEmployee.class [delete] Deleting directory C:\workspaces\test-case\test-case\bin\working [delete] Deleting directory C:\workspaces\test-case\test-case\bin [mkdir] Created dir: C:\workspaces\test-case\test-case\bin copy-resources: [copy] META-INF\persistence.xml added as META-INF/persistence.xml doesn't exist.
