I found out your previous post about log4j wrapper has
the method:
/**
This code (from Ceki Gülcü) checks to see if there are
any appenders defined for log4j which is the
definitive way to tell if log4j is already initialised
**/
private static boolean isConfigured() {
Enumeration enum =
Category.getRoo().getAllAppenders();
if (!(enum instanceof
org.apache.log4j.helpers.NullEnumeration)) {
return true;
}
else {
Enumeration cats
=Category.getCurrentCategories();
while (cats.hasMoreElements()) {
Category c = (Category)cats.nextElement();
if (!(c.getAllAppenders() instanceof
org.apache.log4j.helpers.NullEnumeration))
return true;
}
}
return false;
}
I think I could use it to detect the configuration
error on server start up, could I?
