Switching off Jersey logging programmatically

Question

In my output I have JUL logging messages from Jersey like this

03.12.2010 14:14:55 com.sun.jersey.api.core.PackagesResourceConfig init
INFO: Scanning for root resource and provider classes in the packages:

Programmatically I wanted to swich them off so I tried

Logger.getLogger("com.sun.jersey.api.core.PackagesResourceConfig").setLevel( Level.SEVERE );

or

Logger.getLogger("com.sun.jersey").setLevel( Level.SEVERE );

but this don't work.

Funny enough this global configuration works:

Logger.getLogger( "com" ).setLevel( Level.SEVERE );

or

Logger.getLogger( "" ).setLevel( Level.SEVERE );

WHY?

Answer 1

I had some problems with this so I thought I'd put code in with imports to avoid confusion. I tested this and it works in my mini webserver configuration. Again, I included the whole server implementation for completeness.

import java.io.IOException;
import java.net.URI;
import java.util.logging.Level;
import java.util.logging.Logger;

import javax.ws.rs.core.UriBuilder;

import com.sun.jersey.api.container.httpserver.HttpServerFactory;
import com.sun.jersey.api.core.PackagesResourceConfig;
import com.sun.jersey.api.core.ResourceConfig;
import com.sun.net.httpserver.HttpServer;

public class WebServer {

    private HttpServer webServer;

    private final static Logger COM_SUN_JERSEY_LOGGER = Logger.getLogger( "com.sun.jersey" );

    static {
        COM_SUN_JERSEY_LOGGER.setLevel( Level.SEVERE );
    }

    public void start() throws IOException {
        System.out.println("Starting WebServer\n");
        webServer = createHttpServer();
        webServer.start();
        System.out.println(String.format("\nWeb Server started:" + "%sapplication.wadl\n", getURI()));
    }

    public void stop() {
        webServer.stop(0);
    }

    public static HttpServer createHttpServer() throws IOException {
        ResourceConfig rc = new PackagesResourceConfig("com.daford");
        return HttpServerFactory.create(getURI(), rc);
    }

    private static URI getURI() {
        return UriBuilder.fromUri("http://localhost/").port(4444).build();
    }
}
