7. .NET over IIOP 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

8. .NET over IIOP 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) • C#, J#, Visual Basic .NET, Visual C++ .NET • Any CLR supported language

9. JAVA Janeva compiler .NET C# compiler .jar .NET DLL assembly .ear C# code .class CORBA .idl .NET over IIOP How Janeva Works • 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

10. .NET over IIOP Janeva Environment C# Basic • C++ C# Basic JScript EJB1 EJB2 Obj1 Obj2 • 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) Janeva Stubs Janeva Stubs J2EE Server CORBA .NET Runtime ASP.NET Runtime Janeva Runtime Janeva Runtime RMI-IIOP IDL-IIOP IIOP

11. .NET over IIOP Janeva Environment J2EE Server Environment • 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 Naming Service C# Client Transaction Service Ease-of-Use Layer Assembly Raw Stub Layer EJB Container .NET Runtime Home Objects IIOP Janeva Runtime Remote Objects
