Load a logback.xml Configuration File Programmatically

Today I had a unique situation where I needed to load a logback.xml file programmatically for Logback logging rather than via the standard "from the classpath" way, and here's how I did it. It was quite simple.

The following snippet shows how to load a logging configuration file such as logback.xml programmatically:

LoggerContext context = (LoggerContext) LoggerFactory.getILoggerFactory();
try {

  JoranConfigurator configurator = new JoranConfigurator();
  configurator.setContext(context);
  configurator.doConfigure(logFilePath); // loads logback file
} catch (JoranException je) {
  // StatusPrinter will handle this
} catch (Exception ex) {

  ex.printStackTrace(); // Just in case, so we see a stacktrace

}
StatusPrinter.printInCaseOfErrorsOrWarnings(context); // Internal status data is printed in case of warnings or errors.

Piece of Cake!!
