Web Development
Java Programming
The SEVENAPPS a unit of Web IT Solutions Pvt. Ltd. JavaServer Pages (JSP ) allow web developers to develop content-rich, dynamic pages rapidly and easily. JSP uses XML-like tags to encapsulate the logic that generates web content. JSP pages separate the page logic from its design and display, which prevents the overlapping of roles between web designers and programmers.
Many of these web applications are used to process online forms, tally voting polls, take orders within online stores, allow users to book a flight for their next business trip, or simply to display the user's login name.
The Java technologies you'll use to create web applications are a part of the Java EE platform, in addition to many of the Java Platform, Standard Edition (Java SE) classes and packages. In order for many of these technologies to work on a server, the server must have a container, or web server, installed that recognizes and runs the classes you create. For development and testing of these technologies, you can use the tools detailed in this article, but when you deploy, make sure that the server has Java server software installed to run Java technology-based web applications. If you don't have access to this information, ask the server administrator.
There are too many Java technologies to list in one article, so this article will describe only the ones most frequently used. The number of technologies listed here can appear overwhelming. Keep in mind that you will not need to use them all. In fact, a web application often consists of nothing more than one page created with the JavaServer Pages (JSP) technology. Sometimes you will combine three or more such technologies. No matter how many you end up using, it's good to know what is available to you and how you can use each one in a web application.
Java Servlet API
The Java Servlet API lets you define HTTP-specific classes. A servlet class extends the capabilities of servers that host applications that are accessed by way of a request-response programming model. Although servlets can respond to any type of request, they are commonly used to extend the applications hosted by web servers. For instance, you might use a servlet to get the text input from an online form and print it back to the screen in an HTML page and format, or you might use a different servlet to write the data to a file or database instead. A servlet runs on the server side -- without an application GUI or HTML user interface (UI) of its own. Java Servlet extensions make many web applications possible.
