Here is some code that Ceki sent out earlier. Might need some updating to
use the latest 1.2 classes. It should be noted that this code will not
detect if errors occured during configuration. At least for
DOMConfigurator, errors do not cause it to abort the entire configuration
action.
-Mark
/**
Returns true if it appears that log4j have been previously configured. 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 initialized */
private static boolean isConfigured() {
Enumeration enum = Category.getRoot().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;
}
