The Need to Integrate the Technologies EJB EJB ANATOMY BUSINESS RULES DATA TECHNOLOGY . NET J 2 EE CORBA PROTOCOL n PRESENTATION SOAP RMI IIOP CORBA in the Presentation layer… – Don’t Pass Firewalls, Too Complex and High Maintenance – but… Code is closer to the native platform (better performance) n J 2 EE in the Presentation and Data layers… – Resource Intensive, Too Complex and High Maintenance – but… Portability and Scalability across multiple platforms! n . NET in the Business Rules and Data layers… – No Security, No Persistence, No EJB Analogue – but… Rich Front-End and Easier development environment! Slide 2

Janeva Solution • . NET over IIOP Janeva is Visi. Broker for. NET – Borland’s implementation of CORBA infrastructure for. NET • Adhering to (mature) standards on both the client and server –. NET, J 2 EE, and CORBA • Seamless interoperability between. NET and J 2 EE & CORBA platforms – Access to fully IIOP compliant J 2 EE 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 7
Janeva Solution • • • 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 J 2 EE and CORBA Cross Language Support – Microsoft Common Language Runtime (CLR) – C#, J#, Visual Basic. NET, Visual C++. NET – Any CLR supported language . NET over IIOP
How Janeva Works . NET over IIOP JAVA. jar . NET C# compiler Janeva compiler . NET DLL assembly . ear . class CORBA. idl C# code • Janeva compilers generate. NET stubs for mapping J 2 EE 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 9
Janeva Environment C# Basic C++ C# Basic JScript Janeva Stubs . NET Runtime ASP. NET Runtime Janeva Runtime EJB 1 J 2 EE Server RMI-IIOP • J 2 EE 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) Slide 10 EJB 2 . NET over IIOP Obj 1 Obj 2 CORBA IDL-IIOP
