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. </li> <li> Slide 4 </li> <li> Web Services Client WS SOAP Cont.. </li> <li> Slide 5 </li> <li> 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. </li> <li> Slide 6 </li> <li> J2EE 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) Cont... </li> <li> Slide 7 </li> <li> J2EE EJB, Java Language Cont...

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.

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 Microsofts 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. </li> <li> Slide 13 </li> <li> Differences J2EE &amp;.NET Business Layer Transaction Processing Calling Remote Objects XML web services Data Access Layer J2EE has two types CMP &amp; BMP .NET ADO.NET classes Cont... </li> <li> Slide 14 </li> <li> Differences J2EE &amp;.NET Platform Comparison Cross-platform portability Language support Tools Support Vendor suppor Cont... </li> <li> Slide 15 </li> <li> 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 </li> <li> Slide 16 </li> <li> 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 </li> <li> Slide 17 </li> <li> .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 </li> <li> Slide 18 </li> <li> .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 </li> <li> Slide 19 </li> <li> Questions ????? </li> </ul>
