Unmarshalling interceptor
Hi,
I've a requirement when writing a CXF client. In my webservice response I am getting a list of myData object.
Now I want some group data by iterating over the entire list. The problem is size of the list is high so I don't want to iterate again.
I know the unmarshaller used by the client is doig the same when converting XML to object. If somehow I can intercept while unmarshal and calculate group data then I don't have to iterate.
I want to see some example code using Unmarshal or Pre_Logical or Post_Logical filter.
Thanks,
Abhishek Sharma | -

Hello Abhishek,
you can use the setProviders()-method on the JAXRSClientFactoryBean if you are doing this programmatically.
If you are using the JAXRSClientFactory, there are also create()-methods including the providers parameter.
Here is a good site about how to deal with this in any other way:
cxf.apache.org/docs/jax-rs-client-api.html
Hello Sergey,
no problem. :-)
Best regards,
Marko

Hi Marko,
I added those Marshaller & Unmarshaller Listener properties, was not a
rocket science to do :-), but simplifies things a bit

Hi Marko,
Thanks for the help, but I am doing this unmarshalling in webservice client created using JAXRSClientFactoryBean.
How can I add providers in the webservice client.
Thanks,

Hello Abhishek Sharma,
I think this is a JAXB issue. You can register a Listener to the Unmarshaller.

There are also some examples in the Javadoc of the possibilities.
In order to get this working with CXF, you need to extend the JAXBElementProvider:
(org.apache.cxf.jaxrs.provider.JAXBElementProvider)
Example:
public class MyJAXBElementProvider extends JAXBElementProvider {
// override the methods here like:
protected Unmarshaller createUnmarshaller(Class<?> cls, Type genericType, boolean isCollection) {
Unmarshaller u = super.createUnmarshaller(cls, genericType, isCollection);
u.setListener(MY_LISTENER);
return u;
}
}
Now, register the provider:
<jaxrs:server id="RestServices" address="">
<jaxrs:providers>
<ref bean="MyJaxbProvider"/>
</jaxrs:providers>
</jaxrs:server>
Best regards,
Marko
