I have updated JSONProvider to optionally ignore extra white characters available in mixed content trees, using 'ignoreMixedContent' property. It should fix this issue for you and I reckon it can be generally useful for users dealing with complex schemas, it is still an optional feature though as in some cases the additional content may be needed.
In meantime, here's a workaround (provided you can't change the schema to not require 'mixedcontent'). Have a custom JSONProvider which extends the default one and overrides the method where JSON-aware XMLStreamWriter, on the trunk it's createStreamReader method, but in the CXF version you use it may be marshall(), check the tagged source please. Wrap the created writer in the writer which ignores the additional characters, please check IgnoreMixedContentWriter at http://svn.apache.org/repos/asf/cxf/trunk/rt/frontend/jaxrs/src/main/java/org/apache/cxf/jaxrs/provider/JSONProvider.java Hope it helps, Sergey Sergey Beryozkin-2 wrote: > > I reproduced it now, most likely @XmlMixed is there, with @ XmlAnyElement > > cheers, Sergey > > ----- Original Message ----- > From: "Sergey Beryozkin" <[email protected]> > To: <[email protected]> > Sent: Wednesday, July 22, 2009 12:56 PM > Subject: RE: bad json response > > >> >> Hi >> >> I can not reproduce it at the moment.
