John,
Is isLog4jConfigured() method correct? First and foremost, categories can exist
without any configurator having ever been called. The first part of the test is
clearly wrong. Or?
Second, a configuration need not always attach an appender to root, although that is
not a common situation.
What is wrong with just having a static boolean, say log4jConfigured, and set it to
true after calling a configurator? As in:
public class MyLog4jConfigTracker {
.
.
static boolean log4jConfigured = false;
public
// possibly also static
void init() {
...
if(!log4jConfigured) {
configureLog4jMyWay();
log4jConfigured=true;
}
}
...
}
Am I missing something? Cheers, Ceki
