I added the following annotation to enable cache to one of my EJB3 entities, to test caching with ehCache, where I use Hibernate as the persistence provider: <pre><code>.... import org.hibernate.annotations.Cache; import org.hibernate.annotations.CacheConcurrencyStrategy; @Entity @Table(name = "F") @Cache(usage=CacheConcurrencyStrategy.READ_WRITE) @NamedQueries({ @NamedQuery(name = "F.findAll", query = "SELECT f FROM F f")}) public class F implements Serializable { ..... } </code></pre> I added the following to persistence.xml: <pre><code><property name="hibernate.cache.provider_class" value="org.hibernate.cache.EhCacheProvider"/> <property name="hibernate.cache.provider_configuration_file_resource_path" value="/ehcache.xml"/> <property name="hibernate.cache.use_second_level_cache" value="true"/> </code></pre> And when I try to compile I get the following error: <blockquote> /persistence/F.class): warning: Cannot find annotation method 'usage()' in type 'org.hibernate.annotations.Cache': class file for org.hibernate.annotations.Cache not found An exception has occurred in the compiler (1.6.0_16). Please file a bug at the Java Developer Connection (<a href="http://java.sun.com/webapps/bugreport" rel="noreferrer">http://java.sun.com/webapps/bugreport</a>) after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report. Thank you. com.sun.tools.javac.code.Symbol$CompletionFailure: class file for org.hibernate.annotations.CacheConcurrencyStrategy not found </blockquote> Can anyone help me out here and let me know what I need to do or am doing wrong currently ?

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.
