JAXB : Introduction & Features

JAXB is an acronym of Java Architecture for XML Binding. 

• JAXB provides API to access and process a XML document.
• We can read or write XML files using JAXB.
• SAX and DOM are generic XML parsers& they will parse any well-structured XML. 
• JAXB creates a parser that is specific to your DTD.
• A JAXB parser will parse only valid XML (as defined by your DTD).—DOM and JAXB both produce a tree in memory.
• DOM produces a generic tree, everything is a Node.JAXB produces a tree of Objects with names and attributes as described by your DTD.

Features of JAXB :

• Ease of development
• Typed access to XML content
• Leverage Java SE 5 features
• 100% XML Schema support
• Java classes to XML Schema binding
• Data binding for Java API for XML Web Services (JAX-WS)
• Schema evolution
• Provide optional on-demand validation of XML documents
• Hides the complexity of DOM/SAX APIs
• Is portable (A JAXB application should be able to utilize different JAXB implementations by just regenerating the schema classes and doesn't require change to the actual application code.)
