If you do so, you must still create "otherLogger" in you Logger
class. What does this buy you?
--- cut ---
private static final Log log = LogFactory.getLog(Foo.class);
and log.info(), log.debug(), log.warn()
--- cut ---
works well enough for me. ;-)

I don't understand. Do you suggest having multiple
--- cut ---
public final class Logger {
static {
myLogger = <jdk 1.4 way of getting a logger>
}
public static final void debug(String foo) {
myLogger.debug(foo);
}
[...]
}
--- cut ---
--- cut ---
public final class Logger {
static {
myLogger = <log4j way of getting a logger>
}
public static final void debug(String foo) {
myLogger.debug(foo);
}
[...]
}
--- cut ---
so that you can write Logger.debug(xxx) everywhere or do you suggest
to name them e.g. JDK14Logger, Log4JLogger? In the first case: How do
you get multiple classes with the same name in the jar. In the second
case: How do you resolve the different static class names at runtime?
