I just tried this with log4j 1.2.15 and could not get my location information.
I am calling the log method from a class that uses SLF4J and does
if (logger.isTraceEnabled() && logger instanceof LocationAwareLogger)
{
((LocationAwareLogger)logger).log(FLOW_MARKER, FQCN,
LocationAwareLogger.TRACE_INT, "entry", null);
}
where FQCN is the fully qualified name of my class. This works correctly with
logback. I traced this down and was able to determine that the information
being captured in LocationInfo is wrong. I was able to hack together a bypass
by creating an appender using the same package name as LocationInfo and doing
protected void append(LoggingEvent event)
{
LocationInfo info = event.getLocationInformation();
String fqcn = event.getFQNOfLoggerClass();
Throwable throwable = new Throwable();
StackTraceElement[] steArray = throwable.getStackTrace();
int found = LINE_NA;
for (int i=0; i < steArray.length; ++i)
{
if (steArray[i].getClassName().equals(fqcn))
{
found = i + 1;
}
else if (found != LINE_NA)
{
break;
}
}
if (found == LINE_NA)
{
return;
}
info.className = steArray[found].getClassName();
info.fileName = steArray[found].getFileName();
info.lineNumber = Integer.toString(steArray[found].getLineNumber());
info.methodName = steArray[found].getMethodName();
info.fullInfo = steArray[found].toString();
}
By putting this appender first the correct LocationInfo is returned. BTW - this
code came straight from Logback.
