I am using Apache Common Logging in Desktop Application.
private static final Log log = LogFactory.getLog(Utils.class);
How can I direct, Apache Common Logging to write to disc log file, when I perform
log.error(null, exp);
Thanks.
Commons Logging is basically a wrapper around either Java logging (java.util.logging) or the log4j library. You will need to configure whichever underlying library you are using.
In your example, if I was using log4j (and I generally prefer it to the Java logging system), I would use something like:
log4j.logger.com.mypackage.MyClass = ERROR, FILEA
To specify a file to output to.
It would be worthwhile reading an introduction to log4j if you haven’t already.
