The Apache CXF XJC-Utils subproject provides a bunch of utilities for working with JAXB to generate better or more usable code.

Currently, it consists of the following modules:

cxf-xjc-plugin Provides a maven wrapper around the JAXB XJC utility
cxf-xjc-dv Initialize fields mapped from elements/attributes with their default values
cxf-xjc-ts Implements the toString() method
cxf-xjc-boolean Generate getters named getXXX() for Booleans instead of isXXX()
cxf-xjc-wsdlextension Adds extensions methods to allow generated beans to be used as WSDL4J extensors
cxf-xjc-bug671 Provides a workaround for https://jaxb.dev.java.net/issues/show_bug.cgi?id=671

- Not needed for JAXB >=2.1.12

In CXF versions prior to 2.3.0, the xjc plugins were shaded directly into the big cxf bundle jar. In 2.3.0, they were removed from the jar and are placed individually into the lib directory of the distribution. The xjc plugins are only code generation utilities and not used at all at runtime which is why they were pulled out.

The source code can be checked out anonymously over HTTP by doing:

svn co http://svn.apache.org/repos/asf/cxf/xjc-utils/trunk xjc-utils

Building is similar to the build instructions for the main CXF project.
