Re: java.lang.ClassNotFoundException: org.apache.ojb.broker.util.collections.RemovalAwareCollection

Hi Christopher,

per default OJB use a 
org.apache.ojb.broker.util.collections.RemovalAwareCollection for 
populating 1:n relations. Thus you need this class on client side too.

You can change this default class by setting a
'collection-class' attribute in collection-descriptor.
e.g. org.apache.ojb.broker.util.collections.ManageableArrayList
or your own implementation of ManageableCollection. But you will these 
classes on client side too.

 > Is ojb always returning a java.util.Collection?
per default - yep. More info see
http://db.apache.org/ojb/repository.html#collection-descriptor

regards,
Armin
