i have setup a standalone grizzly/jersey server using maven and referencing the following dependencies
org.glassfish.griz
Check if you can log something with level FINE in your application.
Logger LOG = Logger.getLogger(MyResource.class.getName());
LOG.log(Level.FINE, "a message")
Jersey is using JDK logging and to see its debug output (e.g. in the grizzly console) you have to get the logging configuration right. This configuration file worked for me:
handlers=java.util.logging.ConsoleHandler
.level=FINE
java.util.logging.ConsoleHandler.level=ALL
