title: Programmatically configure Jetty's logger
body: <p>How do I programmatically configure Jetty's logger? I'm using Jetty in a standalone application and want to change the log level of some of Jetty's internally generated warnings. Ideally I could do this programmatically (ie, in code) without having to specify an XML file.</p>
  
  <p>I'm using Jetty 6.1.20.</p>
