How can I implement an OAuth flow in a CXF endpoint (SOAP) in Camel (preferably Blueprint)?

Question

I would like to address a SOAP web service via camel-cxf endpoint. How can I implement an OAuth flow, preferably in the blueprint? Is that configurative or do I have to implement it myself?

I have found nice documentation on this:

Basically, you have to implement interceptors and filters: Your blueprint.xml

<bean id="tvServiceClientFactory" class="org.apache.cxf.jaxrs.client.JAXRSClientFactoryBean">
    <property name="address" value="http://localhost:${http.port}/services/oauth/validate"/>
    <property name="headers">
        <map>
            <entry key="Accept" value="application/xml"/>
            <entry key="Content-Type" value="application/x-www-form-urlencoded"/>
        </map>
    </property>
</bean>

<bean id="tvServiceClient" factory-bean="tvServiceClientFactory" factory-method="createWebClient"/>

<bean id="tokenValidator" class="org.apache.cxf.rs.security.oauth2.filters.AccessTokenValidatorClient">
    <property name="tokenValidatorClient" ref="tvServiceClient"/>
</bean>

<bean id="oauthFiler" class="org.apache.cxf.rs.security.oauth2.filters.OAuthRequestFilter">
    <property name="tokenValidator" ref="tokenValidator"/>
</bean>

<bean id="myApp" class="org.myapp.MyApp"/>

<jaxrs:server id="fromThirdPartyToMyApp" address="/thirdparty-to-myapp">
   <jaxrs:serviceBeans>
      <ref bean="myApp"/>
  </jaxrs:serviceBeans>
  <jaxrs:providers>
      <ref bean="oauthFilter"/>
  </jaxrs:providers>
</jaxrs:server>
