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]

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>
