Effects of the previous enterprise models to Gateway(2)

• We adopted the EJB container methodology- all of the transaction , security and persistency can be done by EJB container of one EJB object

• Serialization of EJB objects carried out with XML document (EJB 1.1 model)

• EJB objects can get the services attached to its container object.

• As EJB can give opportunity of defining attributes for EJB objects and store/restore from Database through JDBC, Gateway implemented same functionality.
