Building Java Servlets with Oracle JDeveloper

Developers today face a formidable task. They need to create large, distributed business applications. The actual creation of any large application is problematic. This development process is compounded when an application is distributed, or if that application resides in multiple pieces across a network. Especially when an Enterprise application must be consistent and reliable across multiple platforms that are scattered across the Web.A major issue concerns the deployment of such applications. On the one hand, the changes are being driven by the rapid growth of business on the Internet, which has created new business models, reduced time to market, and significantly changed the way corporations look at developing and deploying enterprise applications. On the other hand, the Internet also provides the medium for accelerated adoption of distributed computing. It provides standard protocols, like HTTP and IIOP, built on TCP/IP using the World Wide Web browser as its interface, and it allows universal access to these applications. The Internet has created several new classes of applications, such as electronic commerce and self-service applications that need to be integrated with traditional enterprise applications.An issue many enterprises face is the use of applications that are primarily standalone. These applications must be created and launched as quickly as possible without being locked into one platform. The ideal enterprise application would be one that was written once and which would run on all platforms.Java is currently the most dynamic development environment in the industry. It allows you to build a set of tools that can be used on any project with any client and on any platform. Prior to the introduction of Java technology,the dream of code-reuse that was unveiled by the creation of object-oriented programming was not completely fulfilled. If code cannot be reused on every platform, the benefits of code-reuse are limited. With Java technology, you can assure a prospective client that a project is already halfway to completion, and that with this headstart , they will have more time to formulate strategies that will assure them better market positioning. Now there is an ideal solution for the deployment of such applications from the server side, that realizes the goal ofcode reuse within a distributed environment. This solution is servlets What are Servlets? A servlet can be thought of as a server-side applet. Servlets run inside a Server in the same way that applets run inside a Web Browser. A Browser can submit a request to execute a servlet directly, or it can be stand-alone regarding its actions, just as a browser can request an applet directly. Servlets are a powerful addition to the Java environment. They are fast, safe, reliable, and 100% pure Java.Because servlets plug into an existing server, they leverage a lot of existing code and technology. The server handles the network connections, protocol negotiation, class loading, and more; all of this work does not need to be replicated! And, because servlets are located at the middle tier, they are positioned to add a lot of value and flexibility to a system.Because of their flexibility and power, servlets can play a major role in your web application architecture.
