The following exception is thrown when I try to build a session factory. I was under the impression that the "org.hibernate.dialect.PostgreSQLDialect" dialect supports sequences. Am I wrong or is there something wrong with my config.

<id name="id" column="id">
<generator class="sequence">
<param name="sequence">CORDER_SEQ</param>
</generator>
</id>

Any help would be appreciated. Thanks Lee
