EclipseLink/Release/2.4.0/JAXB RI Extensions

Marshaller Features

Cycle Recoverable

Allows the user to write their own logic to be used when object cycles are detected during marshal operations.

Usage: Implement the com.sun.xml.bind.CycleRecoverable interface


Object Identitity Cycle Detection

Used to configure the strategy EclipseLink will use to detect an Object cycle. By default, EclipseLink will use Object identity to determine if a cycle exists; setting this property to false will tell EclipseLink to use the equals() method instead.

Usage: marshaller.setProperty("com.sun.xml.bind.objectIdentitityCycleDetection", false);

XML Declaration

Allows the user to omit the XML processing instruction from marshalled documens. This property is the opposite of Marshaller.JAXB_FRAGMENT, and is included for backwards compatibility only.

Usage: marshaller.setProperty("com.sun.xml.bind.xmlDeclaration", true);

XML Headers

Allows the user to supply a header string, which will appear after the XML processing instruction (<?xml ...>), but before the start of the document's data.

Usage: marshaller.setProperty("com.sun.xml.bind.xmlHeaders", headerString);

Indent String

Allows the user to override the indent string that is used when marshalling objects.


marshaller.setProperty("com.sun.xml.bind.indentString", indentString); marshaller.setProperty(org.eclipse.persistence.jaxb.MarshallerProperties.INDENT_STRING, indentString);

Character Escape Handler

Allows the user to provide their own character-escaping logic by supplying their own implementation of the CharacterEscapeHandler interface.


marshaller.setProperty("com.sun.xml.bind.marshaller.CharacterEscapeHandler", new MyCharacterEscapeHandler()); marshaller.setProperty(org.eclipse.persistence.jaxb.MarshallerProperties.CHARACTER_ESCAPE_HANDLER, new MyCharacterEscapeHandler());


Unmarshaller Features

ID Resolver

Allows the user to provide their own logic for resolving XML IDs/IDREFs.


unmarshaller.setProperty("com.sun.xml.bind.IDResolver", new MyIdResolver());
unmarshaller.setProperty(UnmarshallerProperties.ID_RESOLVER, new MyIdResolver());


XML Location

Allows the user to specify a property on the JAXB object that will be updated (upon unmarshalling) with that object's XML location information (i.e. the line number, column number, and system ID that points to this object's location in the XML input).


Annotate a property with @XmlLocation
