<div class="jive-rendered-content"><p>Hi Community,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I am trying to use Hibernate Tools within Eclipse (Eclipse Juno Service Release 2 on Windows 7 x64, PostgreSQL 9.2 on Debian 6). I was able to set up a Hibernate Configuration. All my data objects are listed under the Configuration node as well as the database can be browsed under the Database node. But a MappingException is thrown for a pg-uuid ID column when trying to open a Session Factory.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Error Message: org.hibernate.MappingException: Could not determine type for: pg-uuid, at table: roles, for columns: [org.hibernate.mapping.Column(id)]</p><p>  </p><p>The affected ID property of the roles entity is defined as:</p><p>  </p><p>          @Id</p><p>          @Type(type = "pg-uuid")</p><p>          @GeneratedValue(generator="hibernate-uuid")</p><p>          @GenericGenerator(name="hibernate-uuid", strategy="uuid2")</p><p>          protected UUID id;</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>We are not experiencing this issue when using the class and configuration with Hibernate 4.1.8 in a Spring MVC application.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>What could we be doing wrong? Is any additional information required to understand this issue? Would this problem better be reported as a bug to the Hibernate Tools team?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Any help is highly appreciated.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thank you,</p><p><br/>Dirk</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>  </p><p>Full Stack Trace;</p><p>  </p><p>org.hibernate.MappingException: Could not determine type for: pg-uuid, at table: roles, for columns: [org.hibernate.mapping.Column(id)]</p><p>          at org.hibernate.mapping.SimpleValue.getType(SimpleValue.java:291)</p><p>          at org.hibernate.cfg.Configuration$1.getIdentifierType(Configuration.java:2217)</p><p>          at org.hibernate.type.EntityType.getIdentifierType(EntityType.java:553)</p><p>          at org.hibernate.type.EntityType.getIdentifierOrUniqueKeyType(EntityType.java:578)</p><p>          at org.hibernate.type.ManyToOneType.getColumnSpan(ManyToOneType.java:120)</p><p>          at org.hibernate.mapping.SimpleValue.isValid(SimpleValue.java:275)</p><p>          at org.hibernate.mapping.ToOne.isValid(ToOne.java:105)</p><p>          at org.hibernate.mapping.Property.isValid(Property.java:217)</p><p>          at org.hibernate.mapping.PersistentClass.validate(PersistentClass.java:464)</p><p>          at org.hibernate.mapping.SingleTableSubclass.validate(SingleTableSubclass.java:66)</p><p>          at org.hibernate.cfg.Configuration.validate(Configuration.java:1193)</p><p>          at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1378)</p><p>          at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:954)</p><p>          at org.hibernate.console.ConsoleConfiguration$5.execute(ConsoleConfiguration.java:278)</p><p>          at org.hibernate.console.execution.DefaultExecutionContext.execute(DefaultExecutionContext.java:63)</p><p>          at org.hibernate.console.ConsoleConfiguration.execute(ConsoleConfiguration.java:107)</p><p>          at org.hibernate.console.ConsoleConfiguration.buildSessionFactory(ConsoleConfiguration.java:273)</p><p>          at org.hibernate.eclipse.console.workbench.LazySessionFactoryAdapter.getChildren(LazySessionFactoryAdapter.java:43)</p><p>          at org.hibernate.eclipse.console.workbench.BasicWorkbenchAdapter.getChildren(BasicWorkbenchAdapter.java:100)</p><p>          at org.hibernate.eclipse.console.workbench.BasicWorkbenchAdapter.fetchDeferredChildren(BasicWorkbenchAdapter.java:106)</p><p>          at org.eclipse.ui.progress.DeferredTreeContentManager$1.run(DeferredTreeContentManager.java:235)</p><p>          at org.eclipse.core.internal.jobs.Worker.run(Worker.java:53)</p></div>
