Accessing XML using Java Technologies
The most important benefit of XML is its simplicity. Though it is simple it is powerful enough to express complex data structures. Java is one of most important programming languages that is used for creating your web pages. It is an object oriented language whose main purpose was to be used with embedded systems such as cell phones. But later it gained more importance to be used with Web pages that were dynamic in nature. Java Applet and servelets are the important mechanisms for implementing this.
