What version of Wink are you using ? If you are using IBM JDK 7.0 you must
upgrade to Wink 1.2.1 which has a fix for some specific issues related to
IBM JDK 7.
As for registering you MessageBodyWriter and MessageBodyWriter in the
application file, see a simple example in
https://svn.apache.org/repos/asf/wink/sandbox/lresende/sample-jaxrs-webapp/
Where the MBW is registered in
https://svn.apache.org/repos/asf/wink/sandbox/lresende/sample-jaxrs-webapp/src/main/webapp/WEB-INF/application
