Slide 2
The Need to Integrate the Technologies
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
• 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
Janeva Solution
• 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)

Janeva compiler
C# code
.NET C# compiler
.NET DLLassembly
• 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
Slide 10
• 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)
