• With JAXB you can:
• Generate JAXB Java classes from an XML schema
• Use schema-derived JAXB classes to unmarshal and marshal XML content in a Java application
• Create a Java content tree from scratch using schema-derived JAXB classes
• Validate XML content during unmarshalling and at runtime
• Customize JAXB schema-to-Java bindings
