Logger

public class StdErrLog
extends AbstractLogger

StdErr Logging. This implementation of the Logging facade sends all logs to StdErr with minimal formatting.

If the system property "org.eclipse.jetty.LEVEL" is set to one of the following (ALL, DEBUG, INFO, WARN), then set the eclipse jetty root level logger level to that specified level. (Default level is INFO)

If the system property "org.eclipse.jetty.util.log.SOURCE" is set, then the source method/file of a log is logged. For named debuggers, the system property name+".SOURCE" is checked, eg "org.eclipse.jetty.util.log.stderr.SOURCE". If it is not not set, then "org.eclipse.jetty.util.log.SOURCE" is used as the default.

If the system property "org.eclipse.jetty.util.log.stderr.LONG" is set, then the full, unabbreviated name of the logger is used for logging.
