Class StdErrLog

java.lang.Object
  org.eclipse.jetty.util.log.StdErrLog

All Implemented Interfaces:

Logger

public class StdErrLog
extends Object
implements Logger

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

If the system property "org.eclipse.jetty.util.log.DEBUG" is set, then debug logs are printed if stderr is being used. For named debuggers, the system property name+".DEBUG" is checked. If it is not not set, then "org.eclipse.jetty.util.log.DEBUG" is used as the default.

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. If it is not not set, then "org.eclipse.jetty.util.log.SOURCE" is used as the default.
