Foil 169 CORBAComponents vs. EJB 1.1

From Object Web Computing Technologies CPS714 Computational Science Information Track -- June 16 99. by H. Timucin Ozdemir
Home and Finder Interfaces
  • CORBA Component model expects the component developer to provide the implementation of those interfaces.
  • EJB produces the implementation of Home and finder operations from the Home interface definition in the ejb-jar file while expecting that the bean developer provides matching ejbCreate() method for each create() method on the Home interface definition.
How these interfaces are obtained by the client:
  • EJB uses JNDI.
  • CORBA Component model uses resolve_initial_references() method of ORB and this can use the CORBA Naming service for locate the interface.
