Are you using Remote Interface when you are calling =
myElement.setPerson(myPerson). The CMRs' only work with local =
interfaces, either pass a local reference or map your remote to local =
with in the  myElement.setPerson.

I hope this helps.

  Hi,

  I'm trying to populate the jboss default DB (Hypersonic)
  using CMR but it doesn't work (I use JBoss 3.0):=20

  I have 2 entity bean (Person and Element) which have
  a relationship 'one-to-many' unidirectionnal.
  When I deploy my component in jboss, it automatically
  create 2 tables in the DB : Element (with a relation column)
  and Person =3D> OK

  When I create a Person entity, jboss just add it=20
  in the Person table =3D> OK
  When I create an Element entity, jboss just add it
  in the Element table (leaving relation column at 'null').=3D> OK
  (I didn't chose to pass a 'Person' directly in the ejbCreate()
  method of the Element entity bean, but just to have=20
  setPerson() and getPerson() methods)

  But when I call myElement.setPerson(myPerson), I get this=20
  error message :
