Foil 22 Session Beans - Home Interaface

From Object Web Computing Technologies CPS714 Computational Science Information Track -- June 16 99. by H. Timucin Ozdemir


1 Home interface
  • creates a new EJB Object,
  • removes an EJB Object,
  • returns the metadata containing information about the enterprise bean. Returned object implements javax.ejb.EJBMetaData interface and can be used by application assembly tools and scripting, and
  • returns a handle object for the home.
2 EJB Object delegates the remote interface calls to the enterprise bean implementation.
3 EJB Object additionally provides operations to get the home's reference, object's handle, test whether two EJB Objects are identical, and remove the object.
4 Session beans are created for the requesting client therefore they have no identity and their home interface does not define finder pattern.
