XML and Java technology are recognized as ideal building blocks for developing Web services and applications that access Web services.
The parsed content is then made available to the application.In the SAX approach, the parser starts at the beginning of the document and passes each piece of the document to the application in the sequence it finds it. The application can take action on the data as it gets it from the parser, but it can't do any in-memory manipulation of the data.For example, it can't update the data in memory and return the updated data to the XML file.In the DOM approach, the parser creates a tree of objects that represents the content and organization of data in the document. The application can then navigate through the tree to access the data it needs, and if appropriate, manipulate it.Now developers have another Java API at their disposal that can make it easier to access XML documents: Java Architecture for XML Binding (JAXB).A Reference Implementation of the API is now available in the Java Web Services Developer Pack V 1.1.Let's look at JAXB in action, and compare it to SAX and DOM-based processing.Suppose you need to develop a Java application that accesses and displays data in XML documents such as These documents contain data about books, such as book name, author, description, and ISBN identification number.You could use the SAX or DOM approach to access an XML document and then display the data. In that case, you would need to: After unmarshalling, your program can access and display the data in the XML document simply by accessing the data in the Java content objects and then displaying it.There is no need to create and use a parser and no need to write a content handler with callback methods.
