Updating xml data using jsp
The following diagram illustrates the process flow of the communication that takes place between the client and server.
This tutorial demonstrates how to construct the auto-complete scenario by following the process flow indicated in the above diagram.
The auto-complete feature saves the user from having to remember the complete name of the composer and can provide a more intuitive and direct path to the sought-after information.
object to pass requests and responses asynchronously between the client and server.
You first create the client-side files for the presentation and functionality needed to generate the When Java-based web projects are created, an Ant build script is automatically generated which enables you to compile the project so that it can be immediately deployed and run on a server that has been registered in the IDE.
One of the advantages of using an IDE is that the editor you work in often provides you with code completion which, if you learn to apply it when you code, can rapidly increase your productivity.
Content here has been adapted from Greg Murray’s article and sample application from Using Ajax with Java Technology. In essence, Ajax is an efficient way for a web application to handle user interactions with a web page - a way that reduces the need to do a page refresh or full page reload for every user interaction.
While learning about the low-level functionality of Ajax, you build a simple application that employs auto-completion in a text field.
The changes are made immediately without requiring a page refresh.
Ajax interactions can be used to do things such as validate form entries (while the user is entering them) using server-side logic, retrieve detailed data from the server, dynamically update data on a page, and submit partial forms from the page.
The IDE’s Source Editor generally adapts to the technology you are using, so if you are working in an HTML page, pressing the code completion key combination (Ctrl-Space) will produce suggestions for HTML tags and attributes.
As will later be shown, the same applies for other technologies, such as CSS and Java Script.
