2. Introduction of RMI: “Remote Method Invocation (RMI) allows applications to call object methods located remotely, sharing resources and processing load across systems.”

3. Features of RMI: • Remote Method Invocation (RMI) facilitates object function calls between Java Virtual Machines (JVMs). This is a powerful feature! RMI allows both client and server to dynamically load new object types as required.

5. Introduction of MFC: • The Microsoft Foundation Class Library (also Microsoft Foundation Classes or MFC) is a library that wraps portions of the Windows API in C++ classes, including functionality that enables them to use a default application framework. • Classes are defined for many of the handle-managed Windows objects and also for predefined windows and common controls. • MFC provides really nice classes for doing Windows programming. • MFC was introduced in 1992 with Microsoft's C/C++ 7.0 compiler for use with 16-bit versions of Windows.

6. Features of MFC: • MFC provides two important classes viz. CWinApp and CFrameWnd, which can be used for creating a window and the application • MFC was introduced, Microsoft extended the C++ syntax with a series of macros for management of Windows messages exceptions, run time type identification, and dynamic class instantiation . • The macros for Windows messages were intended to reduce memory required by avoiding gratuitous Virtual table use and provide a more concrete structure for various Visual C++-supplied tools to edit and manipulate code without parsing the full language. • The message-handling macros replaced the virtual function mechanism provided by C++.

7. Introduction to WebLogic: • WebLogic is an application server: a server program that runs on a middle tier, between back-end databases and application.

8. Features of Web Logic: • WebLogic Server provides a variety of tools for automatically generating deployment descriptors. • WebLogic Server includes a set of Java-based command-line utilities that automatically generate both standard J2EE and WebLogic-specific deployment descriptors for Web applications and Enterprise JavaBeans (version 2.0).

9. Introduction of DCOM: • Microsoft Distributed COM (DCOM) extends the Component Object Model (COM) to support communication among objects on different computers—on a LAN, a WAN, or even the Internet.

10. Features of DCOM: • With DCOM, our application can be distributed at locations that make the most sense to our customer and to the application. • Because DCOM is a seamless evolution of COM, the world's leading component technology . • DCOM handles low-level details of network protocols so we can focus on our real business: providing great solutions to our customers.

11. Introduction of Web Sphere: • WebSphere is a set of Java-based tools from IBM that allows customers to create and manage sophisticated business Web sites.

12. Features of Web Sphere: • The central WebSphere tool is the WebSphere Application Server (WAS), an application server that a customer can use to connect Web site users with Java applications. • WebSphere supports open standard interfaces such as the Common Object Request Broker Architecture (CORBA) and Java Database Connectivity (JDBC) and is designed for use across different operating system platforms. • WebSphere also includes Studio, a developer's environment with additional components that allow a Web site's pages to be created and managed.
