Re: [eclipselink-users] Descriptor/Entity Event Listeners - Registering 
You'll also need to specify the event methods in xml.

Example:

<pre-persist method-name="preInsert"/>
<pre-update method-name="preWrite"/>

Your event methods also need to accept an Object or actual Entity type.

Cheers,
Guy

Subject: [eclipselink-users] Descriptor/Entity Event Listeners - Registering
I can't seem to find any way of registering a Descriptor Event Listener via 
XML definitions. The only documentation on the Wiki is how to do it
programmatically. Is there a way to do it declaratively?
I am attempting to register an Entity Event Listener, but it isn't actually 
working. My orm.xml file:

<entity name="Customer" class="CustomerImpl" metadata-complete="true" >
   <table name="customers">
       <unique-constraint>
    <column-name>id</column-name>
</unique-constraint>
   </table>

   <entity-listeners>
       <entity-listener class="EntityDynamicSchemaSupport"/>
   </entity-listeners>
   <attributes>
       <id name="id">
    <column name="id" unique="true" nullable="false" insertable="true"
updatable="true" />
        <generated-value generator="CustomerSequence" />
       </id>
<basic name="customerNumber">
    <column name="cust_number" unique="true" nullable="false"
insertable="true" updatable="true"/>
</basic>
<basic name="name">
    <column name="name" unique="false" nullable="false" insertable="true"
updatable="true" length="50"/>
       </basic>
   </attributes>
</entity>



And this is my Entity Listener object:



public class EntityDynamicSchemaSupport extends EntityListener {

   public EntityDynamicSchemaSupport() {
       super(CustomerImpl.class);
   }

   @Override
   public void preInsert(DescriptorEvent event) {
       super.preInsert(event);
   }

   @Override
   public void preWrite(DescriptorEvent event) {
       super.preWrite(event);
   }
}


I'm just trying to see how it works for the moment and see the Event
attributes, but when i debug an insert, it never hits these methods. Any
ideas?
