Jaxb

JAXB (Java Architecture for XML Binding) is a Java technology that allows developers to map Java classes to XML representations and vice versa. It simplifies the process of working with XML data in Java applications, making it easier to marshal (serialize) Java objects into XML and un marshal (deserialize) XML back into Java objects.

Key features of JAXB include:

1. XML-to-Java Mapping: JAXB provides annotations that developers can use to map XML elements and attributes to Java classes and properties. This allows for automatic conversion between XML and Java objects.
2. Java-to-XML Mapping: JAXB also supports the reverse process of mapping Java objects to XML. This is useful when you want to convert Java objects into an XML representation for data interchange or storage.
3. Marshalling and Unmarshalling: Marshalling refers to the process of converting Java objects into XML, while unmarshalling is the process of converting XML back into Java objects. JAXB provides APIs for both operations.
4. Schema Validation: JAXB can validate XML data against an XML schema to ensure that the data conforms to the defined structure.
5. Customization: JAXB allows developers to customize the XML representation of Java classes using annotations or by providing binding files that define the mapping rules.

JAXB has been part of the Java Standard Edition (Java SE) since Java 6. However, starting from Java 11, it has been considered a legacy technology and has been removed from the Java SE platform. It is still available as a standalone library and can be used in Java applications with compatible versions.
