Body
I eventually made this "work" - in a hackish sort of way - by turning off schema validation. Previously, I had <code><property name="hibernate.hbm2ddl.auto" value="validate"/>"hibernate.hbm2ddl.auto"</code> in my persistence.xml. When I commented out this property, my app server started and the model "worked". The final form of my entity was: <pre><code>@Entity @Table(schema = "content", name = "theme") public class Theme extends AbstractBaseEntity { private static final long serialVersionUID = 1L; @Column(name = "run_from", columnDefinition = "timestamp with time zone not null") @NotNull @Temporal(TemporalType.TIMESTAMP) private Date runFrom; @Column(name = "run_to", columnDefinition = "timestampt with time zone not null") @NotNull @Temporal(TemporalType.TIMESTAMP) private Date runTo; /* Getters, setters, .hashCode(), .equals() etc omitted */ </code></pre> After reading quite a bit on this, I got the impression is that there is no easy way to map Postgresql timestamp with time zone columns. Some JPA implementation + database combinations support this natively ( EclipseLink + Oracle is one example ). For hibernate, with jodatime extensions, it is possible to store timezone aware timestamps using a normal timestamp + a varchar field for the timezone( I could not do that since I was constrained from changing the database schema ). <a href="http://usertype.sourceforge.net/">Jadira user types</a> or completely custom user types can also be used to tackle this problem. I need to note that my use-case for this entity is "read only", so I could get away with a seemingly naive "solution".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
