I'm not sure what this named root logger you're referring too. In xml 
config it's just root and in property format it's log4j.rootLogger.


I have logging hierarchies where the child logger's name is longer 
than the parent's in a java like way only I sometimes use 
abbreviations of my classes and sometimes use names/levels for 
non-class things. Eg, for a postgresql accessing class:


PQ
PQ.Worker
PQ.TX
PQ.TX.Lookup

I've been building with the GCC on Debian for a few years now without 
any out_of_range errors to do with log4cxx loggers.

exception std::out_of_range in StringHelper::startsWith

[Thorsten Schöning]

Hello,

I get an out_of_range exception everytime I use a logger which name is
longer than the name of the root logger and wonder if anyone else ran
into this problem, too. We use a pretty old Borland Builder 5, may it
be an implementation issue of the stl? Reading how
basic_string::compare works for other implementations the current
startWith should work, in my opinion.

http://www.sgi.com/tech/stl/basic_string.html

I had to make the following changes:

Index: stringhelper.cpp
===
--- stringhelper.cpp(Revision 1652)
+++ stringhelper.cpp(Arbeitskopie)
@@ -79,6 +79,11 @@
 
 bool StringHelper::startsWith(const LogString s, const LogString prefix)
 {
+if (s.length()  prefix.length())
+{
+  return false;
+}
+
 return s.compare(0, prefix.length(), prefix) == 0;
 }

Mit freundlichen Grüßen,

Thorsten Schöning
