hibernate events

Hi, today I tried to add some hibernate event listeners to my
application. This was my first naive approach:

in AppModule
public static void
contributeHibernateSessionSource(OrderedConfiguration<HibernateConfigurer>
config) {
config.add("EventListener", new
EventListenerHibernateConfigurer());

my EventListener
public class EventListenerHibernateConfigurer implements
HibernateConfigurer {

@Inject
SolrIndexer solrIndexer;

@Inject
private HibernateSessionSource hss;

@Override
public void configure(Configuration configuration) {
EventListenerRegistry registry = ((SessionFactoryImpl)
hss.getSessionFactory()).getServiceRegistry().getService(
EventListenerRegistry.class);
registry.getEventListenerGroup(EventType.PERSIST).appendListener(new
MyPersistEventListener(solrIndexer));

First of all I found no way of register an event only with the
configuration object
(http://stackoverflow.com/questions/8616146/eventlisteners-using-hibernate-4-0-with-spring-3-1-0-release).
Second the injection does not work. But how do I get my SolrIndexer into
the my event listener?

Thanks in advance
