Sven Vollbehr commented on WINK-357:
------------------------------------
I have deployed the WAR to ROOT in Tomcat and I have one resource with Path /*.
In the logs I get the following even when I don't get the exception.
January 15, 2012 6:49:42 IP.
org.apache.wink.server.internal.registry.ResourceRegistry filterDispatchMethods
INFO: The system cannot find any method in the mypackage.MyResource class that
supports HEAD. Verify that a method exists.
Hope this helps
