com.sun.jersey.spi.service.ServiceConfigurationError: com.sun.jersey.spi.HeaderDelegateProvider

Error on adding Jersey jars for Restful Webservices:

Fix:

This exception is thrown when Jersey services can not find out specified package and class to instantiate. I verified the correct package where I had my restful service and corrected this path.
