How to get the log information when using a class?

Question

Hi All,
I have a simple question, which I don't know how to solve. I am using org.apache.commons.logging.Log and LogFactory to do some logging. A typical situation is exemplified in the following code snippet.
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
class LogClass {
    private static final Log LOG = LogFactory.getLog(AClass.class);
    public void logit(){
        LOG.debug("This is the debugging log.");
public class AClass{
    public static void main(String[] args) {
        LogClass l=new LogClass();
        l.logit();
}But this way, I do not get the log information from the class LogClass. Could anybody please help?
Many thanks.

...configuration in log4j.xml or log4j.properties.And far as I recall you need one of those two also. If there is no config then there is no output.I thought it used some default config if no file is present, but I could be mistaken. Either way, it adds to the possible problems that the OP could be having, any of which are consistent with his rather vague question.
1) He's passing the wrong class to the LogFactory, and hence getting a logger with the wrong name, so he's seeing a different name than he expects in the output that's being produced.
2) His config file does not contain the proper format to include the actual classname, independent of the logger's name, so he's missing a piece of desired information in each line of the output that's being produced.
3) His config file indicates a threshold that's less verbose than the level at which his code is logging, so no output is present when he wants it.
4) His config file is missing (or not where it's expected to be), so no output is being produced at all.
5) His config file is missing (or not where it's expected to be), so a default level or format is being produced, effectively the equivalent of one of the misconfigurations described in #2 and #3.
Since the OP seems to have vanished, we may never know.
