javax.xml.bind (Jakarta XML Binding API documentation)

Provides a runtime binding framework for client applications including unmarshalling, marshalling, and validation capabilities.

JAXBContext is the client-entry point to the runtime binding framework.

References in this document to JAXB refer to the Jakarta XML Binding unless otherwise noted.

Interface Summary
Interface	Description
DatatypeConverterInterface	The DatatypeConverterInterface is for JAXB provider use only.
Element	This is an element marker interface.
JAXBContextFactory	Factory that creates new `JAXBContext` instances.
Marshaller	The `Marshaller` class is responsible for governing the process of serializing Java content trees back into XML data.
NotIdentifiableEvent	This event indicates that a problem was encountered resolving an ID/IDREF.
ParseConversionEvent	This event indicates that a problem was encountered while converting a string from the XML data into a value of the target Java data type.
PrintConversionEvent	This event indicates that a problem was encountered while converting data from the Java content tree into its lexical representation.
Unmarshaller	The `Unmarshaller` class governs the process of deserializing XML data into newly created Java content trees, optionally validating the XML data as it is unmarshalled.
UnmarshallerHandler	Unmarshaller implemented as SAX ContentHandler.
ValidationEvent	This event indicates that a problem was encountered while validating the incoming XML data during an unmarshal operation, while performing on-demand validation of the Java content tree, or while marshalling the Java content tree back to XML data.
ValidationEventHandler	A basic event handler interface for validation errors.
ValidationEventLocator	Encapsulate the location of a ValidationEvent.
Validator	Deprecated. since JAXB 2.0

Class Summary
Class	Description
Binder<XmlNode>	Enable synchronization between XML infoset nodes and JAXB objects representing same XML document.
DatatypeConverter	The javaType binding declaration can be used to customize the binding of an XML schema datatype to a Java datatype.
JAXB	Class that defines convenience methods for common, simple use of JAXB.
JAXBContext	The `JAXBContext` class provides the client's entry point to the JAXB API.
JAXBElement<T>	JAXB representation of an Xml Element.
JAXBElement.GlobalScope	Designates global scope for an xml element.
JAXBIntrospector	Provide access to JAXB xml binding data for a JAXB object.
JAXBPermission	This class is for JAXB permissions.
Marshaller.Listener	Register an instance of an implementation of this class with a `Marshaller` to externally listen for marshal events.
SchemaOutputResolver	Controls where a JAXB implementation puts the generates schema files.
Unmarshaller.Listener	Register an instance of an implementation of this class with `Unmarshaller` to externally listen for unmarshal events.

Exception Summary
Exception	Description
DataBindingException	Exception that represents a failure in a JAXB operation.
JAXBException	This is the root exception class for all JAXB exceptions.
MarshalException	This exception indicates that an error has occurred while performing a marshal operation that the provider is unable to recover from.
PropertyException	This exception indicates that an error was encountered while getting or setting a property.
TypeConstraintException	This exception indicates that a violation of a dynamically checked type constraint was detected.
UnmarshalException	This exception indicates that an error has occurred while performing an unmarshal operation that prevents the JAXB Provider from completing the operation.
ValidationException	This exception indicates that an error has occurred while performing a validate operation.
