title: Programmatically Enable Logback in Debug Mode?
body: <p>I was wondering if there is a way to enable debug mode programmatically. Since I'm not allowed to use configuration file, I'm currently configure everything programmatically. Recently, I ran into an issue where RollingFileAppender stop writing to file though FileAppender works perfectly fine. In fact, RollingFileAppender was also working last week and nothing that I'm aware of has changed since.</p>
  
  <p>Please let me know if there is a way to enable debug since doing it using configuration file (logback.xml) doesn't seem to be working.</p>
