Sergey Beryozkin commented on CXF-6181:
---------------------------------------
Hi,
Those headers should be part of the rt-rs-extension-providers.
I wonder how JSONProvider (Jettison) is discovered given that it also has no
explicit import headers set.
trunk/osgi/features has a cxf-jaxrs feature installing Jettison first which
probably helps to do the optional resolution.
Should the same be done for DOM4J ? Example, should a DOM4J feature be
installed in a container first before a cxf-jaxrs feature is installed ?
