All Implemented Interfaces:

Logger

public final class Jdk14Logger

extends Object

implements Logger

The default JDK 1.4 wrapper class for Logger. Please note that there is not an exact match to the priority levels that JDK 1.4 logging has and what LogKit or Log4J has. For that reason, the following priority level matching was used:

• SEVERE = error, fatalError
• WARNING = warn
• INFO = info
• FINE = debug

JDK 1.4 does allow you to have other levels like: CONFIG, FINER, and FINEST. Most projects don't separate out configuration logging from debugging information. Also, we wanted to maintain backwards compatibility as much as possible. Unfortunately, with all the "fineness" details, there is no equivalent to the "error" log level.
