Re: How to configure commons-logging on JDK1.4

In my Action I put

System.out.println("--------> " + log.toString());

in front of the log statement to see what Log is used. It always says

--------> [EMAIL PROTECTED]

In my 'commons-logging.properties' file I tried things like this:

org.apache.commons.logging.Log=org.apache.commons.logging.impl.SimpleLog and org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.SimpleLog and org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.SimpleLogFactory

It always uses Jdk14Logger. I don't get it ;-( but maybe a cold beer would help ;-)

Any comments?

Koni,

I find it hard to believe SimpleLog can't be used when using JRE1.4+;
though I'll admit, after looking at the docs, I still don't really know how
to do it.  Have you tried placing the following line in
commons-logging.properties:

org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.SimpleLog

There has to be some way of using it.  Any one with more knowledge have the
answer?

Thanks Jamie
I read an article at http://www.onjava.com/lpt/a/4017 (section Logging,
point 5). There he says explicit:

-----
5. Finally, if none of the above is valid and the application is not
running on JRE 1.4 and above, the application uses a built-in SimpleLog,
which writes everything to System.err.
-----

Because my application runs on JRE 1.4, it uses automatic the
Jdk14Logger. I cannot use SimpleLog on JDK 1.4! Therefore I will use
Jdk14Logger and not Log4J.

Thank you, Koni

Koni,

In short, SimpleLog is not a logging system; some real logging system, be
it log4j or jdk logger or whatever, needs to be sitting under the covers
when using commons-logging.  commons-logging is simply a wrapper around

an

actual logging system.  In my commons-logging.properties file, I have the
following single line, which tells commons-logging to use log4j under the
covers:

org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.Log4jFactory

the Log setup information you listed below would go in log4j.properties,

or its equivalent in any other logging system.

HTHs,

No answer until now! It looks like nobody is using commons-logging!
Very frustrating to be the only one using it...

Is there really no useful example or documentation?

Cheers and enjoy the Friday Beer.

Hello
I'm using Struts 1.1 with commons-logging. My

'commons-logging.properties'

file is in the CLASSPATH and has the following 2 entries:

----
org.apache.commons.logging.Log=org.apache.commons.logging.impl.SimpleLog
org.apache.commons.logging.simplelog.log.LogonAction=info
----

When I run my application the Log should use the 'SimpleLog', as defined
in 'commons-logging.properties'. BUT it uses the default logger for my
environment
org.apache.commons.logging.impl.Jdk14Logger!!!!

How can I configure logging to use 'SimpleLog'?? Any examples??

Thanks
Koni
