The Java docs for j2ee apis says following about the remove method of EJBLocalHome :
public void remove(java.lang.Object primaryKey) throws RemoveException, EJBExceptionRemove an EJB object identified by its primary key. This method can only be used by local clients of an entity bean. An attempt to call this method on a session bean will result in an EJBException.
Throws: RemoveException - Thrown if the enterprise Bean or the container does not allow the client to remove the object. EJBException - Thrown when the method failed due to a system-level failure.
But according to HFE-559 a session bean will throw RemoveException if remove() method is called on EJBLocalHome.
