Error description

  • The following exception is generated:
    
    java.lang.ClassNotFoundException:
    javax.ws.rs.core.MediaType cannot be found by
    com.ibm.websphere.appserver.api.jaxrs20*
    
    The Jackson code (from the jackson 2.4.5 bundle) is
    attempting
    to load the javax.ws.rs.core.MediaType class directly.  The
    jackson_2.4.5 bundle does not import
    javax.ws.rs.core.MediaType so it will fail to load that
    class.
    
    During jackson introspection it is unable to find MediaType
    referenced in IMultipartBody because the
    com.ibm.websphere.appserver.api.jaxrs20 manifest does not
    import JAX_RS interface classes like MediaType and the OSGI
    framework cannot load these type.
    
    One of JAX-RS bundles is not correctly listing all required
    dependencies inside the manifest file

    This problem occurs because the Liberty JAX-RS is not importing
    all of the jars necessary to support the multi-part media type
    resulting in an error similar to the following:
    
    [ERROR   ] CWWKE0701E:
