How does EJB 2.0 improve support for interoperability
between EJB containers and other J2EE products?
Answer / guest
The EJB 2.0 public draft specification includes requirements
on EJB container/server providers which enable
interoperability for invocations on enterprise beans. These
requirements enable communication with J2EE clients
including JavaServer Pages, Servlets, Application Clients as
well as with enterprise beans in other EJB containers. The
goal of these features is to allow enterprise bean
invocations to work even when client components and
enterprise beans are deployed in J2EE products from
different vendors. Support for interoperability between
components includes transaction propagation, naming services
and security services.
The interoperability mechanisms in EJB 2.0 are based on the
IIOP protocol from the Object Management Group. The
extensions supporting distributed transaction propagation,
security (using SSL) and naming service access are all based
on OMG standards. J2EE container products may also use
vendor-specific protocols in addition to IIOP.
