Commons Logging - FileAppender Issue
Hi,
I'm using Log4j to manage log, I want to convert this by Commons Logging
by
converting just this line :
private static Logger sLogger = Logger.getLogger(LoggingManager.class);
by this one :
private static Log sLogger = LogFactory.getLog(LoggingManager.class);
This is the only thing to do, right ?
Now I have a problem : logs aren't stored in files anymore.
Why doesn't it store anymore since I replaced this line to use Commons
Logging ?
Thank u for any help.

Hi
Do you have a configuration file for log4j in your classpath?
What you have done is switched from hardwired log4j to exchangeable
log4j. This means that the user of your product can select which logging
implementation they want to use. In your case you want to use log4j.
With this new setup you still need the configuration file for log4j,
i.e. log4j.properties or log4j.xml.

There are some classloader wrinkles with commons logging 1.0.4 which I
decided to circumvent by stripping down this code to just selecting log4j.
I'd be happy to share if you need it - it is just 6 classes in an
eclipse project.

Thank u.
I can see log4j is used by default and that commons try to find it in
the classpath. So I don't actually need to put anything in commons-
logging.properties. Anyway I tried to make commons-
logging.properties and add
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogg
er
But it still has no effect

Regarding the static give this a read

Because you need to configure commons logging to use whatever
implementation you want ...assume log4j. See the docs. commons-
logging.properties might be what you are after.

Yep, those are all the code changes you need, and in most cases there
are no config file changes needed either.
The only case where you may need to do more are where the code is
running inside a j2ee container or similar, and there are multiple
copies of various logging libraries floating around.

At a guess, there are multiple copies of log4j in your classpath, and
commons-logging is finding one that does not have access to your log4j
configuration file.
Enable commons-logging diagnostic output and see what log4j jarfile is
being detected by commons-logging.

Simon
