EclipseLink/Release/2.4.0/JAXB RI Extensions/Character Escape Handler

Design Documentation: CharacterEscapeHandler

ER 370589

In the current JAXB RI, developed by Sun, there are a series of "proprietary" JAXB extensions that are available to provide advanced JAXB functionality outside of the JAXB spec (these extension classes reside in the com.sun.xml.bind package).

The CharacterEscapeHandler interface provided in the Sun JAXB implementation allows users to write their own character escaping code, to be used when marshalling.

This document will outline the design for an EclipseLink equivalent to this extension.


  • Provide an interface that the user can implement, and use this implementation when escaping characters during marshal.
  • Provide drop-in-replacement support, so that users already using the Sun implementation will not need to change their code when switching to EclipseLink.
