Kenneth,
If you have an instance variable to save the primary key, you can
set it (by calling context.getPrimaryKey() in ejbPostCreate and ejbActivate
and it should always be valid anywhere else you need it (e.g. ejbLoad,
ejbStore, ejbRemove).
Regarding calling myRemoteObject.getPrimaryKey(), you would
have to use the context.getObject() anyway to get the remote
object reference, so you can't avoid using the context in one
way or another to obtain the key.
