The Distributed Object Promotion Group (DOPG), working through committees
(working groups) organized by technical field, is pushing ahead with tests and other
activities for verifying interconnectivity among various types of products that use
the Common Object Request Broker Architecture (CORBA). The Transaction/Component
Working Group, Security Working Group and Interoperability Working Group have now
successfully completed the world's first interconnectivity verification tests in
their respective fields.
- EJB (Enterprise JavaBeans™) interconnectivity verification -
First-stage EJB interconnectivity tests conducted in November this year by
the Transaction/Component Working Group, chaired by Fujitsu Ltd., resulted in the
first-ever verification of EJB interconnectivity among multiple vendor products.
In late 1999, the Group set about extending verification testing to component
technologies, hich are a key technology in Web/Application servers. In the recently
completed verification tests, the Group adopted an "Employee Data Search/Update" a
pplication based on an actual model. Using CORBA 2.3, INS (Interoperable Naming
Service), RMI over IIOP and other fundamental technologies, it interconnected
various EJB products in what amounted to a fusion of all interconnectivity
technologies amassed by DOPG to date. The results verified interoperability with
Session Bean.
The companies participating in the tests were
NEC Corporation
IBM Japan, Ltd.
Nihon Unisys, Ltd.
Hitachi, Ltd.
Fujitsu Ltd.
And EJB products are
WebOTX(NEC Corp.)
BEA WebLogic Server(BEA Systems,Inc.)
WebSphere Application Server(International Business Machines Corp.)
INTERSTAGE Application Server(Fujitsu Ltd.)
TPBroker(Hitachi,Ltd.)
DOPG views the success of the verification tests as a solid first step
confirming the feasibility of interoperation among systems using EJB products in
multi-vendor environments.
- Security interconnectivity verification -
The Security Working Group, chaired by Hitachi, Ltd., conducted first-stage
security interconnectivity verification tests during October and November this
year. The favorable results marked a world first in verification of security
interconnectivity between products of different companies.
The Group's aim was both to respond to mounting customer concern regarding
security and to ensure interconnectivity among the products of different vendors
against
the backdrop of the expanding scale of systems utilizing distributed object
technologies.
Security technologies are capable of preventing unauthorized access by
imposters, message tapping and message alteration. To realize these capabilities,
the Group adopted a mutual server-client authentication system employing a public
key cryptosystem and utilized a proven cryptography technology for message protection.
The tests verified every aspect of interoperability - from interconnectivity
among the cryptographic systems incorporated in the different companies' products
to the format and method of distribution of certificates issued by the authentication
authority.
The companies participating in the tests were
NEC Corporation:WebOTX
Oracle Corporation Japan:Oracle8i
Hitachi, Ltd.:TPBroker
Fujitsu Ltd.: INTERSTAGE Application Server
The technical advances and know-how regarding interconnectivity produced by
the verification tests provide the foundation needed to build safe commercial systems
in multi-vendor environments. The Group is moving to attract a larger number of
verification test members and plans to expand the scope of verification in step with
new developments in security technology and application.
- Interoperable naming service verification -
A series of interoperable naming service (INS) interconnectivity verification
tests ran during November by the Interoperability Working Group, chaired by NEC
Corporation, substantiated interconnectivity between multiple vendor products for the
first time worldwide.
Over the past three years, the Group has focused on verification of IIOP
level interoperability as the quintessence of interoperability. In particular, it
considered interoperability of INS (an extended version of the conventional naming
system) to be critical to interoperation of the broad spectrum of systems with CORBA,
typically Java and EJB products. The verification of INS interoperability through
the interconnectivity tests is therefore especially noteworthy.
The companies participating in the tests were
NEC Corporation:WebOTX
Hitachi, Ltd.:TPBroker
Fujitsu Ltd.: INTERSTAGE Application Server
The success of the verification tests is a significant first step toward
confirming interoperability among diverse systems in multi-vendor environments.
The Group is actively recruiting new verification test participants and, as the next
step, intends to expand and upgrade test content with a focus on, among others, the
extended Internet functions of CORBA/IIOP.
The individual groups are to report the results of their work in detail at
Oracle Open World 2000 to be held at Tokyo Dome on December 14 (seminar times: 3 to 4 PM
and 4:30 to 5:30 PM). They are also to be introduced at the Object Management Group
Technical Committee meeting being held in Orlando, Florida this week.
