Hi Community,

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.

Error Message: org.hibernate.MappingException: Could not determine type for: pg-uuid, at table: roles, for columns: [org.hibernate.mapping.Column(id)]

The affected ID property of the roles entity is defined as:

          @Id
          @Type(type = "pg-uuid")
          @GeneratedValue(generator="hibernate-uuid")
          @GenericGenerator(name="hibernate-uuid", strategy="uuid2")
          protected UUID id;

We are not experiencing this issue when using the class and configuration with Hibernate 4.1.8 in a Spring MVC application.

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?

Any help is highly appreciated.

Thank you,

Dirk
