It has been a long time since I looked at this stuff, but I'm not
sure an entity can remove itself. The one thing I know for certain,
is that calling the ejbRemove remove method has not effect on the
entity state. The ejbRemove method is a callback invoked by the
entity container when the entity container has decided to remove the
entity. If you call this method directly, the entity container does
not see this.
After reviewing the 2.1 spec, I can't see any where that specifies
that entity can remove itself. Every remove example, has another
bean removing the target bean. At the very least, I'd start by
marking the entity as reentrant since a remove is conceivably
reentrancy. Then I'd try, entityContext.getEJB[Local]Object().remove()

Hello, Markus
try this:
Way a (the Collection way):
java.util.Collection<EjbLocal> c=ejbHome.findAll();
EjbLocal delBean=null;
for(EjbLocal l : c){
//find the bean you want to remove: for now, find the last one
delBean=l;
}
c.remove(delBean);
Way b (the usual way):
EjbLocal delBean=ejbHome.findByPrimaryKey(12);
delBean.remove();

Hello Dirk,
I'm not sure what you mean by "collection version of ejbRemove()".
Could you please explain it a little bit more?
Thank in advance,

Hello, Markus
now I get it ^^ (at least I think so)
So, to summarize it: you work with a CMP bean that is used by
various
other beans (JMS in particular). After all things have been done
I want
to remove the bean?
Using ejbRemove() is OK but you may want to use the Collection
version
of ejbRemove. I think (if I remember correctly) that ejbRemove()
always
crashed the EJB container. So I used the collection method. It is a
little bit difficult but it worked.
Give it a try and tell us if it works.
Best regards
Dirk
