  1. J2EE vs. .NET Nigam Patel

  2. Topics • Background • Web Services, J2EE and .NET • Similarities • Differences • Conclusion • Pros and Con (J2EE and .NET)

  3. Web Services • What is Web Services? • Helps applications to be integrated • Foundation of web services is XML messaging over standard web protocol such as HTTP • Can integrate two businesses, departments, or applications quickly and cost-effectively.

  4. Web Services Cont.. Client SOAP WS

  5. J2EE • J2EE architecture is defined by the Sun standards. • Architecture is based on the Java programming language. • Good thing about Java is that it enables the organization to write code once and deploy that code onto any platform.

  6. J2EE Cont... • Partial J2EE components list • JavaServer Pages (JSPs) • Servlets • Enterprise JavaBeans (EJBs) • Java Connectivity Architecture (JCA) • Java Message Service (JMS) • Java Management Extensions (JMX) • Java Naming and Directory Interface (JNDI)

  7. J2EE Cont... Servlets, Java Server Pages Presentation Layer EJB, Java Language Business Layer JDBC compatible DB Data Layer

  8. .NET • .NET is Microsoft Product • Framework of Microsoft .NET offers language independence

  9. .NET Cont... C# CLR MSIL Compiler VB .NET First source code is translated into Microsoft Intermediate Language (MSIL or IL). This MSIL is language-neutral, same as Java bytecode. Then MSIL code needs to be interpreted and translated into a native executable. The .NET Framework includes the Common Language Runtime (CLR), same as the Java Runtime Environment (JRE), which achieves the goal.

  10. .NET Cont... ASP .NET Presentation Layer COM+, Visual Studio .NET Business Layer SQL Server Data Layer

  11. By comparing Big Picture of .NET and J2EE we can Technology similarities Feature J2EE .NET Technology Standard Product Presentation Tier Programming Language ASP.NET Servlets, JSP Business Tier Components EJB, Java Language COM+, Visual Studio .NET Message Queue JMS 1.0 MSMQ Naming Service JNDI ADSI Database Tier Connectivity ADO.NET JDBC Protocol SOAP, WSDL, UDDI SOAP, WSDL, UDDI Interpreter JRE CLR Similarities J2EE & .NET

  12. Differences J2EE & .NET • Presentation Layer In J2EE, JSPs and servlets generate HTML. The servlet includes features like session state, security framework and configuration. In .NET, ASP.NET generates HTML. ASP.NET builds and hosts Web application under Microsoft’s Internet Information Server (IIS). ASP .NET includes stuff like session state, authentication and authorization. With ASP .NET, developer build HTML and custom tags that map to server-side web controls.

  13. Differences J2EE & .NET Cont... • Business Layer • Transaction Processing • Calling Remote Objects • XML web services • Data Access Layer • J2EE has two types CMP & BMP • .NET ADO.NET classes

  14. Differences J2EE & .NET Cont... • Platform Comparison • Cross-platform portability • Language support • Tools Support • Vendor suppor

  15. J2EE (PROS) • Runs on any operating system and application server (may need adjustments) • Handles complex, high- volume, high-transaction applications • Has more enterprise features for session management, fail-over, load balancing and application integration • Is favored by experienced enterprise vendors such as IBM, BEA, SAP and Oracle • Offers a wide range of vendor choices for tools and application servers

  16. J2EE (CONS) • Has a complex application development environment • Tools can be difficult to use • Java Swing environment's ability to build graphical user interfaces has limitations • May cost more to build, deploy and manage applications • Is difficult to use for quick-turnaround, low-cost and mass-market projects

  17. .NET (PROS) • Easy-to-use tools may increase programmer productivity • Has a strong framework for building rich graphical user interfaces • Is tightly integrated with Microsoft's operating system and enterprise server software • May cost less, due in part to built-in application server in Windows, unified management, less expensive tools

  18. .NET (CONS) • Framework runs only on Windows, restricting vendor choice • Users of prior Microsoft tools and technology face a potentially steep learning curve • Questions persist about the scalability and transaction capability of the Windows platform • Choice of integrated development environments is limited • Getting older applications to run in new .Net environment may require effort

  19. Questions ?????
