Presentation Outline
• Java/DCE Background
• Case Study: IntraVerse Console
• Product Delivery: IntraVerse NetSEAT
• Conclusion
Java/DCE Motivations
• Interoperability between Java and nonJava environments
• Integrated authentication between Java
clients and DCE servers
• Integrated authorization between Java
and DCE
• Preserve investment in existing DCE
servers
• Extend DCE to Java platforms
Java/DCE Background
• Chisholm Technologies
– JDCE wraps standard DCE APIs via JNI
– Product currently available
– Acquired by DASCOM Dec 1997
• The Open Group RI
– JADE ATO commenced 1996
– Sponsored by DASCOM, Digital and
Chisholm
– Final snapshot (February 1998) delivered
Java-capable IDL compiler, class library.
JADE Object Model
Interface Class
(Java)
Bind
Java
Applet
or
Application
Method Invocation
RPC Proxy Class
(Java)
DCE RPC
Remote RPC Server
(C/C++)
Case Study: IntraVerse Console
IntraVerse Console: Implementation
• User Registry Interaction
– uses JDCE directly to interact with the DCE
security server
• IntraVerse Server Interaction
– Java-capable IDL compiler used to construct
classes and interfaces
– Generated code called in the same way as
local Java methods.

Benefits of the JADE Approach
• Application code is highly portable
• RPC mechanism does not need to be
understood by application programmers
• Application servers do not have to be Java:
– a controlled strategy for migration to 100% Java
environments
– protects investment in C/C++ DCE application
servers
• Authentication and authorization can be
integrated with other Enterprise services
• JADE Toolset gives a competitive advantage to
application developers
