For UTF-8: <pre><code><property name=”hibernate.connection.useUnicode” value=”true” /> <property name=”hibernate.connection.characterEncoding” value=”UTF-8″ /> </code></pre> <hr> As for setting a combined primary key, it is possible, but having worked with it I can say I wouldnt recommend it. From <a href="http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#entity-mapping-identifier" rel="nofollow noreferrer">the documentation</a>: <blockquote> You can define a composite primary key through several syntaxes: <ul> <li>annotate the component property as @Id and make the component class @Embeddable</li> <li>annotate the component property as @EmbeddedId</li> <li>annotate the class as @IdClass and annotate each property of the entity involved in the primary key with @Id</li> </ul> </blockquote> This becomes a pain to work with, and it isn't the recommended way to do this in Hibernate. What I would recommend instead is to use <a href="http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#d0e2201" rel="nofollow noreferrer">the @NaturalId annotation</a>: <blockquote> While not used as identifier property, some (group of) properties represent natural identifier of an entity. This is especially true when the schema uses the recommended approach of using surrogate primary key even if a natural business key exists. Hibernate allows to map such natural properties and reuse them in a Criteria query. The natural identifier is composed of all the properties marked @NaturalId. </blockquote>

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.
