RE: Can4t write logs

[Lutz Michael <mi...@siemens.com>]

One thing that's "unusual" - using the root logger.  It's generally
recommended to use the getLogger method and name your loggers with the class
FQCN, else you lose much of the power of Log4j (see
http://logging.apache.org/log4j/docs/manual.html).

Q: did you see the console output, and did you not see the output in the
file or did you not find the file?

Hello

I?m using log4j by the first time.

I did the following properties file:

----------------
# Set root logger level to DEBUG and its only appender
to A1.
log4j.rootLogger=INFO, stdout, A1

# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.RollingFileAppender
log4j.appender.A1.File=apliA.log
log4j.appender.A1.maxFileSize=1MB
log4j.appender.A1.maxBackupIndex=3

# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%p %t %c -
%m%n

# stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line
number.
log4j.appender.stdout.layout.ConversionPattern=%5p
[%t] (%F:%L) - %m%n
------------

and in my code I did:

 PropertyConfigurator pcconfig = new
PropertyConfigurator();
        pcconfig.configure("aprop.properties");

        logger = Logger.getRootLogger();
        logger.info("Entering application.");


but when I run the application, I saw "entering
aplication" was not wrote in log file...

What am I doing wrong ?

Thanks in advance

Javier

Thanks for your reply.

Yes, I�ve read the manual but I really don�t
understand this point..

What do you mean with use getLogger with the class.
Which class should I use ? Should I place my
application class name as a parameter to getLogger ?

My application is a little (but powerfull, jeje) class
a file...and only one.

I see the file but nothing inside. Also, I see nothing
in console output..


thanks in advance
Javier

Hi

I�ve been reading the doc again and now I see the
light :)

Then my application now use this:

------------
private static Logger logger =
Logger.getLogger("AplicacionA.class");

PropertyConfigurator.configure("aprop.properties");
        logger.info("Entering application.");

--------------

Now I�ve a new problem (partially solved): if I not
pass a full path to configure method, it can't find my
properties file.

It�s normal this ?
How could I get the current application path ? (I
could imagine writeing a file and getting a path, but
I want to know if there are a more "sophisticated"
method..).

Thanks in advance

Javier
