Sun's
Java Web Services Developer Pack is said to support XML schemas by introducing an early version of JAXP 1.2 which includes schema support.
From the
Java Web Services Tutorial:
Another popular schema language is XML Schema, which is being developed by
the World Wide Web (W3C) consortium. XML Schema is a significantly more
powerful language than DTD, and with its passage into a W3C Recommendation
in May of 2001, its use and implementations have increased. The community of
developers using the Java platform has recognized this, and the expert group for
the Java� API for XML Processing (�JAXP�) has been working on adding sup-port
for XML Schema to the JAXP 1.2 specification. [b]This release of the Java�
Web Services Developer Pack includes support for XML Schema.[/url]
