You do something like this:
public class MyLogger {
private static final String FQCN = MyLogger.class.getName();
private LEVEL infoLevel = LEVEL.FINE;
private LEVEL debugLevel = LEVEL.FINE;
private Logger logger;
public MyLogger(Class clazz) {
logger = new LoggerWrapper(LoggerFactory.getLogger(clazz), FQCN);
}
public void info(LEVEL level, String format, Object[] argArray) {
if (!logger.isInfoEnabled() || !(level.ordinal() <=
infoLevel.ordinal())) {
return;
}
if (logger.instanceofLAL) {
String formattedMessage = MessageFormatter.arrayFormat(format,
argArray);
((LocationAwareLogger) logger).log(null, FQCN,
LocationAwareLogger.INFO_INT, formattedMessage, null);
} else {
logger.info(marker, format, arg1, arg2);
}
}
}

Hey Ralph
Took a look at the call and the wrapper class. My issue I dont want
to esxpose the methods defined in the Logger interface. I only want
to expose my methods for logging. Thats why I did not implement the
Logger interface. Can you suggest how I could deal with the line
number issue with out implementing Logger?
Thanks

Subject: Re: [slf4j-dev] SLF4J Wrapper class line number incorrect
Take a look at XLogger in slf4j-ext.
Out of curiosity, what do you need the wrapper for?

Good Afternoon
I have created a wrapper layer for SLF4J (Listed below). However
the line number are incorrect, it is using the line numbers in the
wrapper class not the class that I called the wrapper from. What is
the correct way to fix this?
