Gopal,
Thanks for the pointer. It seems I can marshall the xml into a
friendly format like in the code below but I am kind of lost as how I
am supposed to work with it now. I have been trying to trace through
the source code to see what happens not getting very far. I was
assuming that marshaller.marshal(entity, doc); would put a Node in the
message so I could get at it with message.getContent(...) from within
an Interceptor but that does not seem the case as I still only have an
OutputStream and a List<Response> when I call
message.getContentFormats() (I have tried moving my Interceptor to
different phases also to see if the Node appears in a different phase
than expected). If I am supposed to play with the XML in the message
body writer where do I put the Node when I am done so the execution
chain can continue as normal? Some more hints would be greatly
appreciated.
public void writeTo(Template entity, MediaType media,
MultivaluedMap<String, Object> map, OutputStream os)
throws IOException {
try {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.newDocument();
JAXBContext context = getJAXBContext(entity.getClass());
Marshaller marshaller = context.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);
marshaller.marshal(entity, doc);
} catch (JAXBException e) {
//TODO: better exception handling
e.printStackTrace();
} catch (ParserConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Best Regards,
- Anthony

You might want to see JAXBElementProvider class you can find marshal

unmarshal jaxb methods
And you can easily override the default JAXB provider by copying it
make the
changes and to register user defined provider.
Here is the example from my app spring context file
<jaxrs:server id="service" address="/">
<jaxrs:serviceBeans>
<bean
class="com.liquid.fulfiller.sample.server.CustomerService"
/>
</jaxrs:serviceBeans>
<jaxrs:entityProviders>
<bean
class="com.liquid.fulfiller.jaxrs.JAXBElementProvider"/>
</jaxrs:entityProviders>
</jaxrs:server>
Hope this help

Hello group,
I very much want to diddle the response xml on it's way out to add
attributes and other bits. Unfortunately I seem to be at a loss of
how
to accomplish this even though it seems like it should be very
easy. I
am using CXF 2.1.1, JAXRS and JAXB if that is of interest.
I have written an Interceptor to test with modeled after what I think
is happening in the LoggingOutInterceptor, placed it in all different
locations on the interceptor chain to see what happens in the message
and I am not finding too much.
If I iterate through message.getInterceptorChain() I get:
org.apache.cxf.interceptor.MessageSenderInterceptor
org.apache.cxf.interceptor.LoggingOutInterceptor
org.apache.cxf.jaxrs.interceptor.JAXRSOutInterceptor
com.mypackage.cxf.ContentsDumpInterceptor
org.apache.cxf.interceptor.MessageSenderInterceptor
$MessageSenderEndingInterceptor
If I iterate through message.getContentFormats() I get:
OutputStream
List
The list is filled with a ResponseImpl as that is what I am returning
from the method invocation.
If I try to print the OutputStream like the LoggingOutInterceptor
does
nothing happens:
public void handleMessage(Message message) throws Fault {
StringBuilder s = new StringBuilder();
try {
CachedOutputStream cos = new
CacheAndWriteOutputStream(message.getContent(OutputStream.class));
cos.writeCacheTo(s);
LOG.info("~~~~~~~~My Message: " + s.toString() );
} catch (IOException e) {
e.printStackTrace();
}
}
Where does the XML live? How to I get at it? Please point me in the
right direction. This must be very simple.
-Anthony
