Subject [jira] Commented: (CXF-2749) org.apache.cxf.configuration.spring.JAXBBeanFactory cannot handle elements with namespace prefixes
Date Thu, 01 Apr 2010 14:44:27 GMT

    [ https://issues.apache.org/jira/browse/CXF-2749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12852406#action_12852406
] 

Daniel Kulp commented on CXF-2749:
----------------------------------


The better workaround would be just use woodstox.   Woodstox is MUCH faster than Sun's implementation
and thus, having woodstox available would help the performance of all the XML processing that
CXF does (which is a lot).   See:

http://fusesource.com/issues/browse/SF-243

for some benchmarks I did.

That said, this is a bug that needs fixing.

> 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>
