Web applications are by nature distributed applications, meaning that they are programs that run on more than one computer and communicate through a network or server. Specifically, web applications are accessed with a web browser and are popular because of the ease of using the browser as a user client.

For the enterprise, the ability to update and maintain web applications without deploying and installing software on potentially thousands of client computers is a key reason for their popularity. Web applications are used for web mail, online retail sales, discussion boards, weblogs, online banking, and more.

One web application can be accessed and used by millions of people. Like desktop applications, web applications are made up of many parts and often contain miniprograms, some of which have user interfaces, and some of which do not require a graphical user interface GUI at all. Also, many applications use only the Java programming language, which is ideal because of its versatility.

A web application can be as simple as a page that shows the current date and time or as complex as a set of pages on which you can look up and book the most convenient flight, hotels, and car Java technologies essay for your next vacation.

In order for many of these technologies to work on a server, the Java technologies essay 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. Java Technologies to Use in Web Applications 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.

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. Java Servlet extensions make many web applications possible.

Figure 1 shows clients talking to Java Servlet extensions. Clients may range in complexity from simple HTML forms to sophisticated Java technology-based applets. HTML servlet classes extend the javax.

Learn more about Java Servlet extensions and navigating with servlets. JSP technology enables rapid development of web-based applications that are server- and platform-independent. JSP technology lets you add snippets of servlet code directly into a text-based document.

Typically, a JSP page is a text-based document that contains two types of text: For instance, you can create a web site of JSP technology pages that use one snippet of code to include the header. This way, when you change a link to a button in the navigation, you make the change in only one file, and that file loads into all the pages on the site that have this code snippet: Because this web page is now a JSP page, you could also go on to add more Java technology code to create dynamic web content, such as polls, forms, ways to enter or retrieve data from a database, and so forth.

Take a look at two helpful documents about creating JSP pages: Instead of mixing tags from numerous vendors in your applications, you employ a single standard set of tags.

This standardization allows you to deploy your applications on any JSP container that supports JSTL and makes it more likely that the implementation of the tags is optimized.

JSTL has iterator and conditional tags for handling flow control, tags for manipulating XML documents, internationalization tags, tags for accessing databases using SQL, and tags for commonly used functions.

The packages you can access for using JSTL are javax. Learn more about JSTL. The main components of JavaServer Faces technology involve a GUI component framework, a flexible model for rendering components in various markup languages and technologies, and a standard RenderKit for generating HTML markup.

A messaging system is a peer-to-peer facility. In other words, a messaging client can send messages to and receive messages from any other client.

Each client connects to a messaging agent that provides facilities for creating, sending, receiving, and reading messages. Enterprise messaging provides a reliable, flexible service for the exchange of business data throughout an enterprise. An example of how JMS might be used is an application that keeps track of inventory for an auto manufacturer.

The inventory component can send a message to the factory component when the inventory level for a product goes below a certain level, so the factory can make more cars.

The factory component can send a message to the parts components so that the factory can assemble the parts it needs.Java Homework Help When you consider the idea that our society uses the technology to minimize the involvement of people in any process, coding .
