Ajax in Oracle JDeveloper

Asynchronous JavaScript and XML (Ajax) is a web technique used to
transfer data between a browser and server asynchronously without
posting the web page to the server. "Asynchronously" implies that the
processing of the web page continues while the Ajax request is sent to
the server and a response is received from the server. The web page, or
section(s) of the web page, is refreshed with the Ajax response without
reposting the web page. Ajax has the following advantages over non-Ajax
web applications.

- Reduced response time and reduced server load, as the complete web
page is not reposted.

- Reduced bandwidth of web applications as only data is transferred and
the HTML format is applied in the browser.

- Separation of data, format and style. The book covers web search and
RSS Feed with Ajax as well as form validation with Ajax frameworks for
Java, JSP, JSF, and PHP. It discusses using Ajax in Oracle JDeveloper
and is IDE based. JDeveloper has the following advantages over Eclipse
IDE.

- JDeveloper 11g provides an integrated JavaScript Editor for Ajax/Web
development.

- It also provides a PHP extension.

- JDeveloper has a built-in support for JSF and for JDBC.
