Subject [jira] Commented: (CXF-2626) xmlbean databinding nullpointer
Date Tue, 19 Jan 2010 17:29:54 GMT

    [ https://issues.apache.org/jira/browse/CXF-2626?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12802355#action_12802355
] 

Sergey Beryozkin commented on CXF-2626:
---------------------------------------

> Using org.apache.cxf.jaxrs.provider.XMLBeansElementProvider as a jaxrs:provider works
like a charm, thanks 

Excellent, thanks for confirming it. Please test XMLBeansElementProvider, it was contributed
awhile back, we can add some more properties to it if needed. Example, the schema you register
above will be ignored by XMLBeansElementProvider, so may be we can update it to do the XMLBeans
schema validation. Can XMLBeans validate the data ? If you know how then I can update the
provider. 

> I'll try to make a test case/simpler service reproducing the bug above, but that will
not be for a week or two.

ok, no probs, given that XMLBeansElementProvider works, it is not that critical then...

cheers, Sergey
