Grizzly Standalone Logging

Question

i have setup a standalone grizzly/jersey server using maven and referencing the following dependencies

  org.glassfish.griz         


        

Answer 1

I've just had to solve the same problem. Here is my initialization code that convinces Grizzly HTTP server to display errors: http://source.apidesign.org/hg/bck2brwsr/rev/18ae4fbcfb87

Logger l = Logger.getLogger("org.glassfish.grizzly.http.server.HttpHandler");
l.setLevel(Level.FINE);
l.setUseParentHandlers(false);
ConsoleHandler ch = new ConsoleHandler();
ch.setLevel(Level.ALL);
l.addHandler(ch);

I am using Grizzly 2.3.3

Answer 2

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

Answer 3

Grizzly uses JDK logging API. Not sure why it doesn't work for you, double check that java.util.logging.config.file property is getting properly resolved.
