You have a classpath problem. This class is normally part of the JDK since
Java 5. Does your EnterpriseApp or WebApp contain an own copy of it (look
into xml_apis.jar or some versions of xercesImpl.jar)? Main problem is that
the factory is provided by Java SPI mechanism (it is somewhere registered in
a jar's META-INF/services/javax.xml.datatype.DatatypeFactory), but the
instantiated class and the interface are nor compatible (because loaded by
different classloaders).
You may also try latest XStream SNAPSHOT (see download page), it has a
modified class initialization and it should ignore this problem (at the cost
of not registering DurationConverter).
Thanks for your reply.
I tried with this Jar (xstream1.4.2) but getting same issue. Can you mail me
the correct version.
