Changing json provider in server and client

[Dan King]

Hi,

I'm aware that I can change the default jettison json provider to jackson by 
adding the below xml, but what configurations, if any, must I change on the 
client side? I'm using cxf-bundle-minimal-2.3.2

    <jaxrs:providers>
           <bean class="org.codehaus.jackson.jaxrs.JacksonJsonProvider">
            <property name="mapper">
             <bean
                class="com.rest.json.ObjectMapperFactoryBean">
            </bean>
            </property>
           </bean>
    </jaxrs:providers>
    <jaxrs:extensionMappings>
        <entry key="json" value="application/json" />
        <entry key="xml" value="application/xml" />
    </jaxrs:extensionMappings>

Are there any major pitfalls I should be wary of when deciding to make a change 
to either jackson or gson? Thanks.
