RE: duplicate logging?
Hi Paul, Based on the manual and what you said, this is what I did: I am logging events in 2 classes, viz. com.sap.A - with corresp. logger com.sap.A com.sap.B - with corresp. logger com.sap.B In the props file, I write: log4j.additivity.com.sap.A=false log4j.additivity.com.sap.B=false as in each case I want the logging to stop and not go higher up the heirarchy. Is this right? I still get the same result though.. one line all be itself and the other line following the pattern I specify.. thanks, Rishi --- Paul Smith [EMAIL PROTECTED] wrote: On Thu, 2003-08-28 at 06:32, Rishikesh Tembe wrote: Is this how its done? log4j.rootLogger.additivity=false Close, but no cigar. The Log Event starts getting logged at it's own Logger (say, the com.mycompony.mycomponent Logger, and gets logged up the hierarchy until it reaches the root Logger, so you need to set the addidivity at the Logger point where you wish to stop going up. So if you want the LogEvent to start and stop at it's own logger: log4j.additivity.com.mycompany.mycomponent=false (note that additivity is first) If you wish all com.mycompany and their children Log events to stop logging there log4j.additivity.com.mycompany=false Once it's reached the rootLogger, it can't go any higher, so your setting has no effect. The short manual has a good discussion on it: http://jakarta.apache.org/log4j/docs/manual.html (see the section on Appender additivity). cheers, Paul Smith - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] = Yahoo!

I do the same for the other class, com.sap.AINNode, which is running on
another machine. I have a log4j.properties file with

Thanks for this, it helps a lot. What you appear to be doing, if I make
it out correctly, is creating a SECOND appender using Java code that is
a complete duplicate (apart from the pattern). Is there any need? Is
the appender specified in the configuration file ok to use?
What I would recommend is:
a) remove the Java code dealing with configuring appenders, I just can't
see a good reason for it there (hard coding appenders is a maintainence
nightmare). Leave it to the configuration file.
b) the code logger = Logger.getLogger(com.sap.EventThread), make sure
this is only called once! Best practice is to make the logger variable
a private static final. the Logger.getLogger call is not exactly cheap,
just get a reference as early as possible, and use it everywhere in your
class. It's thread-safe, don't worry.
c) You define the appenders in the configuration file, and you identify
which Loggers the appenders get attached to. You will notice your
config file:
log4j.rootLogger=INFO, d1
This attaches the named appender 'd1' to the Root logger. I'd recommend
removing this so it is just:
log4j.rootLogger=INFO
Now attach your d1 logger to your com.sap.EventThread logger like so:
log4j.logger.com.sap.EventThread=INFO,d1
This should work a treat. Let me know how you go.

Adding more complete support for l7d and ResourceBundle
Hi, I am interested in internationalizing my logging messages and I see that I can use the l7dlog() methods on Logger to accomplish this. I am interested only in l7d at the source rather than at the destination so these methods are perfect (i.e. I don't need to do l7d in the appenders). Like several others on this list I would like to be able to easily configure the ResourceBundle that is associated with each Logger. I believe that I can accomplish this by creating a custom LoggerFactory. I want to explain my proposed approach and see if anyone has feedback on it. I will create a custom LoggerFactory that takes a single parameter - the desired Locale expressed as language code, country code, and variant. When the factory instantiates a new logger it will first call super() which will yield a new Logger object. I am planning to use the package structure to define my loggers and I will call ResourceBundle.getBundle(loggerName, locale) with the logger name and the supplied locale (or without the locale if none is provided). When I obtain the ResourceBundle I will assign it to the Logger using Logger.setResourceBundle(). If I get fancy I may search for a ResourceBundle higher up in the package structure if I don't find one specific to the class (i.e. first look for com.package.MyClass then com.package, then com). Does anyone have any comments or suggestions on this approach? Thanks, Mark - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Yes, although the property/xml files are the way to go. Just Log stuff in your Java code, and don't worry about where it's going. Then, later on, you can put on your Where should my log statements go hat and deal with what should be appended where/when in the configuration file. This separation makes Logging nice and clean. cheers, Paul Smith - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hi all, I am using Lo4j 1.2.8, During the cource of my application running i deleted the log file. Now there is no exception/error thrown.

RE: Behaviour in Log4j when Logfile is deleted.
That may be YOUR guiding factor but it is NOT the common guiding factor. Log4j was designed to meet the large majority of needs, not your specific needs /soapbox. I do not want my web app to come crashing to a halt because someone accidentally deletes an active logfile or log4j is misconfigured. If this is your requirement, you are probably going to have to either: 1) Customize log4j to change it's failure mode 2) Implement customized logging where logging is part of the application and logging failure is as critical as an application failure. You can easily add a warning to the console if the log file is deleted but log4j doesn't continually throw warnings for a reason: it kills performance. -Original Message- From: Raveendranath, Rohith (LNG - AUS) [mailto:[EMAIL PROTECTED] Sent: Thursday, August 28, 2003 17:30 To: 'Log4J Users List' Subject: RE: Behaviour in Log4j when Logfile is deleted. whetrher logging activity is critcal for any application will be the guiding factor to decide whether the application should crash i case of logging failure.

RE: Log file location
Ceki and Jake..Thanks for the suggestions..I have used a separate appender for my
package.
I've defined a new appender in log4j.xml of JBoss as follows:
appender name=myFileApp class=org.jboss.logging.appender.RollingFileAppender
param name=File value=${jboss.server.home.dir}/log/myapp.log/
param name=Append value=false/
param name=MaxFileSize value=500KB/
param name=MaxBackupIndex value=1/
layout class=org.apache.log4j.PatternLayout
param name=ConversionPattern value=%d %-5p [%c] %m%n/
/layout
/appender
And I have defined a category for my package as follows:
category name=com.mypackage
priority value=ERROR/
appender-ref ref=myFileApp/
/category
where myFileApp is the appender that I have defined.
This worked and I can see the log messages of my application in a separate file
(myapp.log).

However, nothing prevents you from configuring a repository in your
applications.
As for using and installing JNDIRS, JBoss has very cool ways for
installing plugins. You might want to write a plugin that installs JNDIRS
(JNDI Repository Selector) through org.apache.log4j.LogManager's
setRepositorySelector() method.
All this might be somewhat complicated at the beginning. Why don't you
just configure the log4j settings of JBoss? Wouldn't that be the easiest
option?

Ceki,
I'm trying the way you have mentioned at
http://www.qos.ch/logging/sc.html (using LoggerRepository).
In my java class, I have the following code:
(I'm using JNDIRS you've mentioned in the above URL)
private static final JNDIRS jndirs = new JNDIRS();
private static final LoggerRepository loggerRepository =
jndirs.getLoggerRepository(); private static final Logger logger =
loggerRepository.getLogger(MyApp.class.getName());
logger.warn(Just testing a log message with priority set to WARN);
My log4j.properties file is as follows:
appender writes to a file
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%-5p: %m%n
log4j.appender.R.File=errors.log
Still I feel that my log4j.properties file not being read, because I
can't see errors.log created anywhere. And there are no errors
throws.
Any idea what could be the problem? Can you pl. suggest a solution?

We should have a look at the jboss mailing lists. JBoss' class loader
is called UnifiedClassLoader. The last time I look at
UnifiedClassLoaders about a year ago, it seemed very smart. I'd have
to look at the details again.

Well, if you your app is seeing jboss/lib/log4j.jar in preference
to WEB-INF/lib/log4j.jar, then there is a bug in JBoss. The
Servlet spec states that (contrary to the normal Java2 classloading
scheme) classes and libraries in WEB-INF/classes and WEB-INF/lib
are checked first for classloading and if the classes are not found
there, only then does it look to a higher classloader to attempt to
load the classes.
I know JBoss has some concept of a single classloader across the
whole server (I think that is what I read), but if it doesn't allow
for a separate WebappClassLoader, then I think it is a spec
compliance violation. What does the JBoss group have to say about
this? Putting log4j.jar in WEB-INF/lib *should* provide a
completely separate logging environment from the one JBoss uses.

I ran some tests on my machine yesterday.

RE: Behaviour in Log4j when Logfile is deleted.
Log4j will never throw an exception through its printing methods (Logger.debug(), Logger.info(), ...). However, it will print a warning message on the console. That is the default behavior which can be customized using error handlers. It is entirely possible for the Java io API to silently ignore the fact that the file is gone. That is a Java issue and log4j cannot do anything about it.

RE: Class FileWatchdog
The watchdog code in log4j 1.2.x does not have a notion of a lifecycle. In particular, LogManager.shutdown does not stop the watchdog thread. Actually, I don't think there is a way to stop a watchdog thread which is definitely a serious shortcoming of log4j watchdogs. This omission can prevent dead classloaders from being garbage collected in web-containers. For example see: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22478 Thus, my recommendation would be to avoid using watchdogs for the time being in J2EE environments.

Re: how do I log an exception stacktrace
In special circumstances you might want each line of the stacktrace to be
full log lines (i.e., with loglevel, MDC, threadname, etc). In this case you can
use Throwable.getStackTrace() to get the individual line, and then do something like
public static void logError(Logger log, Throwable ex, int limit) {
if (log.isDebugEnabled()) {
StackTraceElement[] ste = ex.getStackTrace();
for (int i = 0; i ste.length; i++) {
if (i == limit) {
return;
}
if (i==0) {
log.debug(ste[i]);
}
else {
log.debug(\t + ste[i]);
}
}
}
}
I use this when I need to see a stacktrace when I grep through the log
file for a paricular thread, say.

implemented so
that classes and resources packaged within the WAR are loaded in
preference to
classes and resources residing in container-wide library JARs.
Note the use of the word 'recommended' and not 'required'
FWIW, I have always ended up punting on this one and placing my log4j
configuration into the jBoss server's log4j.xml file. Perhaps jBoss 4.X
has addressed this (I have not used it yet)?

Well, if you your app is seeing jboss/lib/log4j.jar in preference to
WEB-INF/lib/log4j.jar, then there is a bug in JBoss. The Servlet spec
states that (contrary to the normal Java2 classloading scheme) classes and
libraries in WEB-INF/classes and WEB-INF/lib are checked first for
classloading and if the classes are not found there, only then does it
look to a higher classloader to attempt to load the classes.
I know JBoss has some concept of a single classloader across the whole
server (I think that is what I read), but if it doesn't allow for a
separate WebappClassLoader, then I think it is a spec compliance
violation. What does the JBoss group have to say about this? Putting
log4j.jar in WEB-INF/lib *should* provide a completely separate logging
environment from the one JBoss uses.

Hi Jake,
Thanks for the information. I have gone through the stuff you've written.
Here's what I'm doing:
1. I placed log4j-1.2.8.jar in WEB-INF/lib
2. I placed log4j.properties in WEB-INF/classes
3. I deployed the application on JBoss 3.2.1
By default, JBoss has log4j.jar in jboss/lib which is in my classpath.
So, even my application class loader takes the classes from log4j.jar
located in jboss/lib?
If I remove log4j.jar in jboss/lib, then I think I will not get server
log of JBoss.
How to solve this issue? Please inform.

Hi Sriram,
Do you have log4j.jar in WEB-INF/lib? If not, I'd expect default
initialization not to work. Remember that the webapp class loader can see
parent class loaders, but the parents cannot see the webapp class loader,
hence your log4j.properties will definitely not be found. If you are
trying to use log4j.jar in a parent class loader and want your own
configuration file to be used in your own logging space, then you will need
to use a repository selector. See the log4j-sandbox for working
examples. I wrote something up about this stuff here...

I placed it in WEB-INF/classes.
Still it's not being read.
I am JBoss and JBoss contains log4j.jar by default and it has log4j.xml
in
default/conf folder.
Probably even my application is taking log4j.xml from that location by
default. I need to check that. Anyone who has implemented log4j for their
applications on JBoss, pl. suggest.

Hi,
I am unable to set log file location. I searched the forum for old

My log4j.properties file is as follows:
log4j.rootCategory=WARN, dest1, R
log4j.appender.dest1=org.apache.log4j.ConsoleAppender
log4j.appender.dest1.layout=org.apache.log4j.PatternLayout

log4j.appender.R.File=d:/jboss/errors.log
I packaged by application as .ear and deployed it on JBoss running
on Win 2000.
When I run the application, I can see the log messages on JBoss
console, but these messages are not getting stored in the file I've
specified (d:/jboss/errors.log).
What could be the problem? In fact, initially I tried
${jboss.home}/errors.log, but it didn't work. So I thought of hard
coding the file location and tried it out. Still the same problem.
Can someone please suggest a solution?
