I inhertied a project that is using log4j. A framework was added that
wraps log4j and now the method is no longer visible in the output. I
get back the log4j wrapper method. How can I get back the calling
method?

The first implementation was to just add the following to each class
static Category log =
Category.getInstance(requestHandler.class.getName());
And then do something as follows
log.debug("Initializing request handler");
In the log4j.properties is defined as such
log4j.appender.disk.layout=org.apache.log4j.PatternLayout
log4j.appender.disk.layout.ConversionPattern=%d{DATE} [%p] %M - %m%n
And output look like such

It was changed to use a Logging framework that wraps log4j
public class Logger {
protected static String categoryName = Logger.class.getName();
public Logger(String filename){
init(filename);
}
private Logger(){}
private void init(String filename) {
Properties props = null;
try {
props = PropertiesUtils.loadAsResource(filename);
PropertyConfigurator.configure(props);
//getCategory(categoryName).info("Log4j initialized using
file :"+filename);
}catch(ConfigurationException ce){
getCategory(categoryName).error("log4j properties file '"+
filename +"' not found. It must be in the CLASSPATH");
System.out.println("log4j properties file '"+
filename +"' not found. It must be in the CLASSPATH");
}
}
public boolean isDebugEnabled(String categoryName) {
return getCategory(categoryName).isDebugEnabled();
}
public void debug(String categoryName, Object message) {
getCategory(categoryName).debug(message);
}
public void error(String categoryName, Object message) {
getCategory(categoryName).error(message);
}
public void error(String categoryName, Object message, Throwable t)
{
getCategory(categoryName).error(message,t);
}
//etc
protected Category getCategory(String categoryName) {
return Category.getInstance(categoryName);
}
}
Then in each class something like this
protected static final String CLASS_NAME = MyLogic.class.getName();
Logger.getInstance().debug(CLASS_NAME," process input stream");
Log4jproperties
log4j.appender.disk.layout.ConversionPattern=%d{DATE} [%p] %M - %m%n
