                      Distributed Object Promotion Group completes
                      world's first successful EJB, security and
                      INS interconnectivity verification tests
                      in multi-vendor product environments
                      #
                             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.
