java.util.UUID cannot be used for Ids ------------------------------------- Key: HHH-6188 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6188 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.3 Environment: Hibernate 3.6.3Final, Oracle 9i Reporter: Thomas Oellrich Assignee: Gail Badner Fix For: 4.0.0.next Attachments: Foo.java, foo.sql, FooTest.java, fullstacktrace.txt Hibernate successfully maps java.util.UUID to a database field defined as raw(16) in Oracle. However, as soon as I add the @Id annotation from the JPA-API, I get the following error: Caused by: org.hibernate.MappingException: No Dialect mapping for JDBC type: -2 at org.hibernate.dialect.TypeNames.get(TypeNames.java:77) at org.hibernate.dialect.TypeNames.get(TypeNames.java:100) at org.hibernate.dialect.Dialect.getTypeName(Dialect.java:296) at org.hibernate.mapping.Column.getSqlType(Column.java:208) at org.hibernate.mapping.Table.sqlTemporaryTableCreateString(Table.java:371) at org.hibernate.mapping.PersistentClass.prepareTemporaryTables(PersistentClass.java:774) at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:272) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1845) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:906) I'm using org.hibernate.dialect.Oracle9iDialect.
