Interface LoggingOutput

All Known Implementing Classes:

CommonsLoggingOutput, ServletLoggingOutput

public interface LoggingOutput

We don't want to force users to use commons-logging, but there are no logging APIs available at 1.3 so this lets us use Servlet.log if commons-logging is not available.
