If all you are looking for is a configuration safe Hierarchy, then try:
private Logger logger = ConversionLoggerFactory.getLogger(getClass());
Where:
import org.apache.log4j.Hierarchy;
import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
import org.apache.log4j.helpers.Constants;
import org.apache.log4j.helpers.Loader;
import org.apache.log4j.spi.RootCategory;
public class ConversionLoggerFactory {
private static final ConversionLoggerFactory c_instance = new
ConversionLoggerFactory();
public static Logger getLogger(final Class c) {
return c_instance.m_hierarchy.getLogger(c.getName());
}
private final Hierarchy m_hierarchy;
private ConversionLoggerFactory() {
m_hierarchy = new Hierarchy(new RootCategory(Level.DEBUG));
new
PropertyConfigurator().doConfigure(Loader.getResource(Constants.DEFAULT_CONF
IGURATION_FILE), m_hierarchy);
}
}
There's no need to wrap/subclass logger, just specify where you would like
to find configuration safe instances of it.
Cheers.

Subject: ClassCast exception for factory
I am trying to implement a new logger factory to get around a problem I
posted earlier. I am failing with a classcast exception on the statment
below:
private ConversionLogger logger = (ConversionLogger)
ConversionLogger.getInstance(this.getClass());
The ConverstionLogger and ConversionLoogerFactory are based exactly on the
excamples in source.
After trying to figure out how to specify the factory in the properties
file, I came across an answer like below:
log4j.categoryFactory=com.ca.cleverpath.portal.migrate.importer.Conversi
onLoggerFactory.class
But I still get the classcast.
Can someone help on this?
thanks
