How to remove null from JSON Output in JAXRS service , CXF 3.0.6 and jackson:2.9.1

[Kulbhushan Azad]

hi ,

i am trying to remove the null values from my json response,However , i am
not able to get it removed.
i am using CXF 3.0.6 and jackson:2.9.1.
How can i troubleshoot this? how do i see which jsonprovider is being used?
how can i get rid of the null values ?

i have a POJO with below annotation at the class level.

@JsonInclude(JsonInclude.Include.NON_NULL)

and below is the rest service spring configuration

   <jaxrs:server id="testService" address="/test">
            <jaxrs:serviceBeans>
                <ref bean="testBean" />
            </jaxrs:serviceBeans>
            <jaxrs:extensionMappings>
                <entry key="xml" value="application/xml" />
                <entry key="text" value="application/text" />
                <entry key="gzip" value="application/gzip" />
                <entry key="octet-stream" value="application/octet-stream"
/>
            </jaxrs:extensionMappings>
            <jaxrs:providers>
                <ref bean="jsonProvider" />
            </jaxrs:providers>
            <jaxrs:features>
                <cxf:logging />
            </jaxrs:features>
    </jaxrs:server>

    <bean id="jsonProvider"
class="com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider" />
