Weblogic 12.2.1 Infrastructure Jersey Jackson Configuration

Question

I'm using Jersey 2.22.1 on Weblogic 12.2.1. The managed server has a Jax-RS v1 service deployed. Jackson isn't working correctly and iThe non-json services are working as expected.

The error:

WARNING: The following warnings have been detected: WARNING: Contract interface javax.ws.rs.ext.MessageBodyReader can not be registered for component class com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider: Contract not assignable to component.

Pom.xml (there is a property setting jersey.version 2.22.1):

I changed my weblogic.xml to prefer package-name com.fasterxml.jackson.*, which was in the prefer-application-resources section above and it works correctly now. Here is a snippet of my weblogic.xml:

 <wls:container-descriptor>
    <wls:prefer-application-packages>
        <!-- jsr311 -->
        <wls:package-name>javax.ws.rs.*</wls:package-name>
        <!-- javassist -->
        <wls:package-name>javassist.*</wls:package-name>
        <!-- aop repackaged -->
        <wls:package-name>org.aopalliance.*</wls:package-name>
        <!-- jersey 2 -->
        <wls:package-name>jersey.repackaged.*</wls:package-name>
        <wls:package-name>org.glassfish.jersey.*</wls:package-name>
        <wls:package-name>com.sun.research.ws.wadl.*</wls:package-name>
        <!-- hk2 -->
        <wls:package-name>org.glassfish.hk2.*</wls:package-name>

        <!--jackson-->

    </wls:prefer-application-packages>
    <wls:prefer-application-resources>

        <wls:resource-name>META-INF/services/javax.ws.rs.ext.RuntimeDelegate</wls:resource-name>
        <!-- jersey -->
