Hi all, 
I am working with Jboss 5 beta 4, JPA und the HSQL Database. 
This is my JoinTable definition in class Subscription:

@ManyToMany(targetEntity=com.sap.sii.pubsub.entity.Subscriber.class, fetch = FetchType.EAGER)
  | 			joinColumns = @JoinColumn(name = "SUBSCRIPTION_ID", referencedColumnName = "SUBSCRIPTION_ID"), 
  | 			inverseJoinColumns = @JoinColumn(name = "SUBSCRIBER_ID", referencedColumnName = "SUBSCRIBER_ID"))
  | public ArrayList<Subscriber> getSubscribers() {
  | 		return subscribers;
  | }
The other side in class Subscriber:@ManyToMany(targetEntity=com.sap.sii.pubsub.entity.Subscription.class, fetch=FetchType.EAGER, mappedBy="subscribers")
  | public ArrayList<Subscription> getSubscriptions() {
  | 		return subscriptions;
  | }
And there is the table SII_PUBSUB_SUBSCRIPTION_SUBSCRIBER with the columns SUBSCRIPTION_ID andSUBSCRIBER_ID. But when I persist the entity this table is empty but there is are the columnssubscriptions and subscribers with some data looking like object references:([B at 7f8124) in the tables of subscription and subscriber.
