org.apache.cxf.configuration.spring.JAXBBeanFactory cannot handle elements with namespace prefixes
--------------------------------------------------------------------------------------------------

                 Key: CXF-2749
                 URL: https://issues.apache.org/jira/browse/CXF-2749
             Project: CXF
          Issue Type: Bug
          Components: Configuration, Transports
    Affects Versions: 2.2.6
         Environment: Only when used with Sun StAX implementation 1.4.2; does not seem to
happen with Woodstox
            Reporter: Jonathan Whitall
            Priority: Minor


I first noticed this when attempting to define the http:conduit element in a Spring config
file:

<beans:beans xmlns:http="http://cxf.apache.org/transports/http/configuration"
	xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation=" 
          http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans.xsd
          http://cxf.apache.org/transports/http/configuration   http://cxf.apache.org/schemas/configuration/http-conf.xsd
          ">

	<http:conduit name="*.http-conduit">
		<http:client ConnectionTimeout="30000" ReceiveTimeout="120000" />
	</http:conduit>

</beans:beans>

It always fails with the following exception:

Caused by: javax.xml.bind.UnmarshalException
 - with linked exception:
[javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,198]
Message: http://www.w3.org/TR/1999/REC-xml-names-19990114#ElementPrefixUnbound?http&http:client]

Looking at the source code, it appears that CXF is sending the body contents of http:conduit
verbatim to JAXBBeanFactory for parsing into a JAXB object. Apparently, Woodstox doesn't care
if there is an unregistered namespace prefix, but the Sun StAX implementation does and throws
the exception.

My current workaround is to define the http:conduit element in a separate XML file and use
it as the default namespace like this:

<beans:beans xmlns="http://cxf.apache.org/transports/http/configuration"
	xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation=" 
          http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans.xsd
          http://cxf.apache.org/transports/http/configuration   http://cxf.apache.org/schemas/configuration/http-conf.xsd
          ">

	<conduit name="*.http-conduit">
		<client ConnectionTimeout="30000" ReceiveTimeout="120000" />
	</conduit>

</beans:beans>
