CORBA in the Presentation layer…
– Don’t Pass Firewalls, Too Complex and High Maintenance
– but… Code is closer to the native platform (better performance)

J2EE in the Presentation and Data layers…
– Resource Intensive, Too Complex and High Maintenance
– but… Portability and Scalability across multiple platforms!

.NET in the Business Rules and Data layers…
– No Security, No Persistence, No EJB Analogue
– but… Rich Front-End and Easier development environment!

Janeva Solution
•
.NET over IIOP
Janeva is VisiBroker for .NET
– Borland’s implementation of CORBA infrastructure for .NET
•
Adhering to (mature) standards on both the client and server
– .NET, J2EE, and CORBA
•
Seamless interoperability between.NET and J2EE & CORBA platforms
– Access to fully IIOP compliant J2EE servers
– Access to fully IIOP compliant CORBA ORB's
•
Highly performing
– Leveraging efficiencies of IIOP vs. SOAP
•
Enterprise Quality of Service (IIOP based)
– Load Balancing, Fault Tolerance, Transactions, Scalability

Slide 8
Transactions
– Provide 2-Phase commits across applications
Security
– Encryption, Authentication, and Authorization
Stateful Services
– Object References
– Distributed Object Model
Support for Complex Data Types
– Automated mapping between J2EE and CORBA
Cross Language Support
– Microsoft Common Language Runtime (CLR)
– C#, J#, Visual Basic .NET, Visual C++ .NET
– Any CLR supported language

.NET C# compiler

.NET DLL
assembly
.ear
.class
CORBA
.idl
C#
code
• Janeva compilers generate .NET stubs for
mapping J2EE and CORBA types to .NET types
• The .NET C# compiler compiles the generated
stubs and include them in the compiled assembly
• Janeva runtime is embedded directly into the
deployed application

RMI-IIOP
• J2EE based compiler
– .Net Remoting stubs from Java RMI interfaces
• CORBA based compiler
– .Net Remoting stubs from IDL
• .NET Assemblies
– Packaged from generated stubs
– Stubs target Microsoft’s Common Type System (CTS)

Hiding the Complexities
– Ease-of-Use Abstraction (OO wrappers)
– Map J2EE and CORBA frameworks to .Net
– Tight integration with .NET based IDE’s such as Visual Studio for .NET
and C# Builder
