log4j configuration ignored for inner classes
Hi all, I am trying to cut back on some of the logging noise from the Spark / Kafka frameworks by editing log4j.properties. However, it seems like package-specific customisations are ignored for inner classes. For example, the following configuration lines mostly work as expected, suppressing most logs from these packages below WARN level: log4j.logger.org.apache.spark=WARN log4j.logger.kafka.utils=WARN However, I am still getting log messages at INFO from classes like: org.apache.spark.Logging$class kafka.utils.Logging$class I suspect it's because these are inner classes. It still happens even when I go up a level and add configurations like "log4j.logger.org=WARN". Is this a known bug in log4j? Is there any known way to suppress these, ideally through configuration rather than programmatically? Many thanks
Re: Problems with log4j configuration [SOLVED]
Well guys!
I finally made it... The problem was not with log4j, but with the EAR
generation of the legacy code I have here... >-(
Thanks for the help and for the hints! They'll be usefull in the future for
sure... :-D

RE: Problems with log4j configuration
I've noticed a very strange thing just now!
While debugging, I've stoped in a point when my logger is called to log
something... But when I evaluate my logger, it says: "logger cannot be
resolved"
This is very bizarre, cause when I try to log something with
logger.info("bla") for example, it doesn't throws any exception... %-|

Hi Bart!
I've checked and I'm importing log4j correctly... =)
Here's the import line: import org.apache.log4j.Logger;
Thanks for the help! :-)

RE: Problems with log4j configuration
Hi bmelloni!
Thanks for all these good sugestions, but unfortunately none worked for
me... :-((
What I've done:
1) Look in server.log and see if your entries might be going there.
I've used grep in all my log files and my application console, and a
random string that I've put there didn't appeared... I've used a break point
in debug mode to be sure that my logger was called... :confused:
2) Check for typos.
I've double checked for typos, but I don't think this is the case...
3) Try implementing your AUDITOR appender by cut/pasting the FILE appender
that is there as a starting point.
I've made this too, copying and pasting another configuration logger
that's already working in another package, but it didn't work too... :-((
4) Instead of using static and specifying the class use "private final
Logger logger = Logger.getLogger(this.getClass());"
I've tried this strategy too, and it was not effective again... :,(
I really have no idea what might be happening... It seems that everything is
alright, but my Auditor.log keeps empty... :confused:

If you let your IDE add the import statements, double-check that you're
importing log4j's Logger and not JBoss's Logger.

log4j configuration for rollover and compression
Hi, Can someone please let me know how to configure log4j.properties file for the below requirement : 1. I need to rollover the log files on the basis of both size and time whichever earlier (example : rollover the log files if they cross 10MB or at the end of each day which ever occurs first) 2. The rolled over files need to be compressed in gz format. 3. Once the number of rolled over + compressed files (archive) reaches 10 then i need to start deleting the oldest archive. I have log4j-1.2.13.jar and apache-log4j-extras-1.1.jar in the classpath of my web application. logback is not an option for me and I need to get this done using log4j. Thanks, Yash -- View this message in context: http://old.nabble.com/log4j-configuration-for-rollover-and-compression-tp33074307p33074307.html Sent from the Log4j - Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: log4j-user-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-user-h...@logging.apache.org
Re: Verification of log4j configuration file
Thank you, Josef, very detailed explanation! - To unsubscribe, e-mail: log4j-user-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-user-h...@logging.apache.org
AW: Re: Verification of log4j configuration file
Hi Antonio
I suggest to you the following.
1. Take NetBeans or any other IDE and catch the log4j open sources as a project.
2. Build log4j yourself,
3. JDK 6.0, maven 2.2.1 and ant 1.7 and a few other lesser important things is
all you need
4. Do BUILD using NetBeans. / you can use also from a dos window mvn install
comand
5. Select build.xml and ask for the javadoc ANT target to get doc and API's
built
6. Then start your TrowableProperty or DOMConfiguratir development
basically you have to consider a few Configurators
BasicConfigurator
Is extended by the
PropertyConfigurator(reading config data
from a property file)
OR
DOMConfigurator (reading config data from a XML
file)
Either of the two can be extended by your own
TrowablePropertyConfigurator
OR
TrowableDOMConfigurator
You may develop your own TrowablePropertyConfigurator or
TrowableDOMConfigurator and engage it as shown in the Java Class below but this
time inside a try catch block.
So where is your TrowablePropertyConfigurator engaged?
Look at the file Log4JTest.java written by ThomasFenner under
./contribs/ThomasFenner (here included as reference)
You can see that this test catches exceptions if drives are not installed? OK?
And you can see which and how the PropertyConfigurator is engaged?
Now, at this stage we would engage your own TrowablePropertyConfigurator or
your own TrowableDOMConfigurator
import org.apache.log4j.*;
import java.sql.*;
import java.lang.*;
import java.util.*;
public class Log4JTest
{
// Create a category instance for this class
static Category cat = Category.getInstance(Log4JTest.class.getName());
public static void main(String[] args)
{
// Ensure to have all necessary drivers installed !
try
{
Driver d =
(Driver)(Class.forName("oracle.jdbc.driver.OracleDriver").newInstance());
DriverManager.registerDriver(d);
}
catch(Exception e){}
// Set the priority which messages have to be logged
cat.setPriority(Priority.INFO);
try
{
// Configuration with configuration-file
//PropertyConfigurator.configure("log4jtestprops.txt");
TrowablePropertyConfigurator.configure("log4jtestprops.txt");
}
catch(Exception e){}
// These messages with Priority >= setted priority will be logged to the
database.
cat.debug("debug"); //this not, because Priority DEBUG is less
than INFO
cat.info("info");
cat.error("error");
cat.fatal("fatal");
}
}
For further understanding:
Go to the ./docs/api/org(apache/log4j/PropertyConfigurator.html
Open this and study what the PropertyConfigurator does for you?
And you will find you confirmed that no exceptions are raise by log4j's
PropertyConfigurator for whatever reason.
Can you extend the PropertyConfigurator and extend and implement
TrowablePropertyConfigurator ! Certainly you can.
Finally do not forget to ask somebody from the developers group to help you
check in your working/tested source code.
Maybe somebody more know to the subject can comment my suggestions

Betreff: Re: Re: Verification of log4j configuration file
Thank you, Josef,
however I would like to force log4j return me an error code or throw
an exception (however docs says it never throws anything) in case of a
malformed config file to stop my application. Otherwise all logs will
cause exceptions and will not appear anywhere.
What is the best practice for an application to behave in case of
malformed log4j conf file?

Re: Re: Verification of log4j configuration file
Thank you, Josef, however I would like to force log4j return me an error code or throw an exception (however docs says it never throws anything) in case of a malformed config file to stop my application. Otherwise all logs will cause exceptions and will not appear anywhere. What is the best practice for an application to behave in case of malformed log4j conf file? - To unsubscribe, e-mail: log4j-user-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-user-h...@logging.apache.org

Re: Doubt about log4j configuration and OCI
I don't think you can load the Oracle native driver more than once (that
tries to load the native bits/dlls more than once, and that's what the
"Native Library already loaded" is about).
A couple of choices are to try to use the existing DataSource (which I
don't think JDBCAppender can do out of the box, though I'd be surprised if
no one has fixed that), or trying to leave the driverClassName off (if
possible) so that you rely on the driver that was loaded earlier. (That's
assuming the log4j appender is the later of the two to load, and that the
JDBCAppender will let you leave off the "driver" parameter).

Doubt about log4j configuration and OCI
Hello,
I have a doubt about how to configure log4j in order to avoid the error
java.lang.UnsatisfiedLinkError: Native Library
C:\oracle\product\10.2.0\client_1\BIN\ocijdbc10.dll already loaded in
another classloader
I want log write the log in the same database as the other sql statements I
need for my application.
I have a DAO Connection class with this method:
public static Connection getConnection()
{
InitialContext initContext = new InitialContext();
Context envContext = (Context)
initContext.lookup("java:/comp/env");
DataSource dataSource = (DataSource)
envContext.lookup("jdbc/testdb");
return dataSource.getConnection();
}
This method uses the DB info placed in META-INF/context.xml file:
Then I have my log4j.xml files configured like that:
But when I execute the first log.debug statement (the connection class has
been already executed), I receive the error
java.lang.UnsatisfiedLinkError: Native Library
C:\oracle\product\10.2.0\client_1\BIN\ocijdbc10.dll already loaded in
another classloader
Any idea?
Thanks in advance.

Re: how to access and manipulate the log4j configuration programmatically
Sure. You can query appenders from logger objects and manipulate everything programatically. There used to be an application called LogWeb [1] that did this, but seems to have fallen off the face of the earth. The code was licensed under Apache2, if I recall correctly, so I would think it would still be available somewhere? In any case, there's a simple ConfigurationServlet [2] in the Log4j sandbox that you can try to get started quickly.

I tried using

But still the configuration is not getting reflected !
Any idea?

Thanks Yair for the reply!
I have used property file only.
The thing is the property file is open and if someone edit it and restart the
java process he would be able to see all the DEBUG logs (which contains some
critical information)
I dont want this to happen so want to change at runtime (in code) the
configuration!

Why not use a regular property file?
Then when you to update the file you can load the changes automatically
using the "PropertyConfigurator.configureAndWatch" mechanism.

Changing log4j configuration runtime ...
Hello all,
I have successfully configured log4j in my standalone java application
using PropertyConfigurator.configure()
Here is the configuration file
log4j.rootLogger=DBUG, LogFile
log4j.logger.com.server.core=INFO
log4j.logger. com.server.core.SecurityManager =DEBUG
log4j.logger. com.server.core.SecurityPatternsCreator =DEBUG
log4j.appender.LogFile=org.apache.log4j.RollingFileAppender
log4j.appender.LogFile.File=c:/server.log
log4j.appender.LogFile.MaxFileSize=5MB
log4j.appender.LogFile.MaxBackupIndex=10
log4j.appender.LogFile.layout=org.apache.log4j.PatternLayout
log4j.appender.LogFile.layout.ConversionPattern=%d{
MM dd HH:mm:ss:SSS}# [%-5p]# [%t]# %c# %C{1}.%M# %m%n
In case of my application I have a security related library
(securitylib.jar) in which there we do some is a critical security
related processing. And I want to set logging level of "INFO" to all the
classes/loggers from this jar.
The log4j configuration is done before loading securitylib.jar using
above configuration file.
When securitylib.jar is loaded I tried to re-configure log4j using
following code.
(what I have done here is removed all the explicit loggers set in
configuration file, updated the configuration properties and configured
logger again)
But when I test the system I am still able to see the DEBUG logs for
classes/loggers com.server.core.SecurityManager and
com.server.core.SecurityPatternsCreator (which I had marked as DEBUG in
config files)
My questions are ...
1. Why after reconfiguring the loggers the new configuration is
not getting reflected ?
2. Is there any way to get the current log4j configuration and
change it at runtime ?
Thanks in advance for your help!

Just put your property file into the classpath and you do not have to
worry about initialization of log4j framework. It does it automagically
when you fetch the first logger.

Hi Sebastian,
What I tend to do is have a class to do something similar but first check
whether already configured: my class is called LogConfigureCheck and is used in
a static block for all my JUnit tests thus...
static {
LogConfigureCheck.check();
}
...and here follows a version of the class suitable for redistribution.

static log4j configuration statement
Hi all,
I use standard static code to include the log4j configuration:
static {
PropertyConfigurator.configure("file"));
}
But this code is not always executed, depending on if the class in which
this is included particpates in execution. But if I add this statment to
other classes too,
I sooner or later get double-messages as two classes with this statement
are used. Then I need to manually remove the code in one of them to
achieve proper logging.
How this is done right? I just want to have this configuration stated
once and applicable to the whole project.
Thanks for help!

RE: Syslog message is sent twice in the case no log4j configuration file is used
Thx Heri for answering!
Following code unfortunately produces the same problem. I still receive
the message twice.
m_logger = Logger.getRootLogger();
m_logger.setAdditivity(false);
m_syslogAppender = new SyslogAppender();
m_syslogAppender.activateOptions();
m_syslogAppender.setLayout(new PatternLayout("%c: %m%n"));
m_syslogAppender.setSyslogHost("localhost");
m_logger.addAppender(m_syslogAppender);
m_syslogAppender.setFacility(mapFacilityID(this.m_facility));
sendLogMessage(logMessage);
m_logger.removeAllAppenders();
The only thing what I could imagine is that in the case there is no
configuration file defined the system automatically generates a standard
configuration with a standard syslog appender. To avoid this I tried to
set the Additivity to false.
I also called the "getAllAppenders()" in order to count the added
appenders but I only got the right number of one!
Has somebody any other ideas?

My only guess is that setting the additivity flag by code does not have
any effect. Or maybe a kind of activateOptions() on the logger must be
performed.
Why dont you fetch the RootLogger for appending your syslog appender, as
you do in your config example? After the log call you clear the
appenders anyway.

Re: How can I tell which log4j configuration file is being used?
The logic for selecting the configuration file is in the LogManager.java log4j class. The environment variable you're looking for might be: DEFAULT_INIT_OVERRIDE_KEY Do you remember where you set this? I'd like to know how you stop it looking at both files and instead allow the user to do BasicConfigurator.configure(); First log4j will look for the log4j.properties files Then if it doesnt find this it will look for the log4j.xml file If you want to see which one is has selected, use -Dlog4j.debug in your JVM arguments when you run your program. -- View this message in context: http://www.nabble.com/How-can-I-tell-which-log4j-configuration-file-is-being-used--tp17353608p17364347.html Sent from the Log4j - Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Dynamic log4j configuration
I'm working on a project where we want to dynamically configure log4j during a run. We want to change log levels, appenders, and filters in real time. The "configureAndWait()" method doesn't look like it would work well for our needs because: 1) It would be a performance hog if we wanted it to act "real time" (delay < 500 ms) 2) We don't want to persist configuration changes from run to run (and if we write to the file that would be the default) So I was thinking of loading the config file, and for dynamic changes simply changing the properties objects and calling the reset and configure methods. I am confused, though, on why the PropertyConfigurator doesn't allow dynamic changes to filters (and only the DOMConfigurator does). I looked at the DOMConfigurator briefly and I see that it calls the "addFilter() method of appender" Is there any reason why the PropertyConfigurator doesn't do this? Would it be ok for me to use a PropertyConfigurator, and call "addFilter()" to deal with filter changes myself? I ask because I think connecting a UI with DOMConfigurator would be a bit clumsy, I'd have to hand craft XML for each change I want to send back.

AW: multiple web application in same web container using different log4j configuration
Hi Jake, thanks for your answers. And yes, I realized that 1.3 is dead. I will switch back to the 1.2 branch as far as possible.

Re: Forcing XML configuration file to reset Log4J configuration
Thanks Matthew.
We're talking about a JBoss environment using the configureAndWatch type
of mechanism to pick up the XML configuration changes.
There is no way to fully reset and reload the configuration w/o
restarting the logging service?
Matthew Kemp wrote:
To reset an entire configuration you need something like this:

Unfortunately, even the DOMConfigurator.configureAndWatch() only does
an incremental reload.

RE: Log4j Configuration
Ed --
Here's my recommendation:
1) Create a class that extends java.io.PrintStream.
2) In this class, override the public void println(String) method. In
the overridden method, evaluate the string that's being written. If the
string that's being written begins with "log4j:ERROR ", then record the
fact that log4j has encountered an error.
3) Before log4j loads it's configuration, replace System.err with your
extension of java.io.PrintStream.
4) Let log4j configure itself.
5) After the configuration is complete, restore System.err to the
original PrintStream and check your extension of java.io.PrintStream to
see if log4j wrote any error messages to System.err.
Here's some code:
// This is my extension of java.io.PrintStream
public class MyPrintStream extends PrintStream {
private List log4jErrors = new ArrayList();
public MyPrintStream(OutputStream out) throws FileNotFoundException
{
super(out);
}
public void println(String x) {
// Record any errors that originate from log4j.
if ((x != null) && (x.startsWith("log4j:ERROR "))) {
log4jErrors.add(x);
}
super.println(x);
}
public String[] getLog4jErrors() {
String[] result = new String[log4jErrors.size()];
result = (String[])log4jErrors.toArray(result);
return result;
}
}
// This class demonstrates how this would work.
private void runTest() {
try {
// Setup a new error stream.
MyPrintStream myPs = new MyPrintStream(System.err);
PrintStream oldErr = System.err;
System.setErr(myPs);
// Configure log4j.
DOMConfigurator.configureAndWatch("log4j.xml");
// Since my configuration has no errors in it, log4j didn't
write
// anything out to it's 'raw' logger. So, just for testing
purposes,
// I am going to write some messages out to log4j's 'raw' logger
in
// order to illustrate how you can respond to any errors that
occur
// during configuration. In a 'normal' situation, you would not
do
// this.
LogLog.error("Something bad has happened!!");
LogLog.error("This is an exception", new Exception(
"This is the exception"));
// Restore the old error stream.
System.setErr(oldErr);
// Check to see if log4j wrote anything out to System.err
String[] errors = myPs.getLog4jErrors();
if ((errors != null) && (errors.length != 0)) {
System.out.println("log4j recorded " + errors.length
+ (errors.length == 1 ? " error." : " errors."));
for (int i = 0; i < errors.length; i++) {
System.out.println("log4jErrors[" + i + "]="
+ errors[i]);
}
System.exit(1);
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}

However I want the option to exit application if ANY of log4j configuration fails. By default I am seeing a warning message from Log4j but application continues to run...

Re: Can I change log4j configuration programatically?
I don't change the logging config in code so I am not familiar with
that but you should only have to change the level of loggers with an
appender attached (at most).

some default stuff. Now the cofig file may change the settings ie. logging

}
Another question is, at this point, I have use getLogger for a lot of

Using configureAndWatch you can just change the file and it will update based on the changes.

Re: Can I change log4j configuration programatically?
A stand-alone Java application could use
DOMConfigurator.configureAndWatch (but don't allow it to do automatic
configuration).

Ok, now I'm restarting and now the "takeover" is complete - even after a restart a single webapp's config is applied to every other webapp. Regarding a parent classloader, I'll have to look into it, although I'm positive that each context has its own log4j.jar (even different versions among some) and either a log4j.xml file or a log4j.properties file. I'm double-dog sure about that ;) The tomcat is running standalone, version 5.5.12 running on BEA's JRockit jvm, version 1.5.0_04-b05 Is there a way to "debug" or "trace" the classloader? thanks for your response, Javier On 1/10/06, Jacob Kjome <[EMAIL PROTECTED]> wrote: > > I'm not sure why it wouldn't be happening on initial startup, but is it > possible > that the webapp is finding a log4j.xml file in a parent classloader, which > would > be used in preference (by Log4j's auto-configuration mechanism) to > log4j.properties in each webapp?

Re: log4j and tomcat, context taking over log4j configuration for the whole enchilada?
I'm not sure why it wouldn't be happening on initial startup, but is it possible that the webapp is finding a log4j.xml file in a parent classloader, which would be used in preference (by Log4j's auto-configuration mechanism) to log4j.properties in each webapp? If that's not the case, you aren't, by chance, running Tomcat-5.5 under JBoss or something like that, are you?

Hi, I've got a tomcat 5.5 server running a bunch of webapps, each one with its own copy of log4j.jar and log4j.properties. Each one does terse logs to the tomcat console and a detailed log to a separate log file for each webapp. The problem is that, when I reload a context, that context's log4j configuration seems to take over the log4j configurations of every webapp, and all the applications start logging with that configuration, which is no good at all, since the terse logs now all come formatted with the reloaded context's pattern, and the verbose logs are lost since the only verbose log file logged to is the reloaded context's, while the other log files sit untouched, and every additivity configuration of the other webapps is lost.

changing log4J configuration during run time
Hi, In log4J, if I change the configuration i.e. increase/decrease the level of a particular logger or add more appenders/categories in the config file, then do I have to restart the web server for that setting to take effect. What I understand from the documentation is that if I use DOMConfigurator.configureAndWatch(, ) then I don't have to restart the server. Is this the only way to change the logging configuration during run time or there are some other ways also? If you use this method, then a thread is launched which continously monitors the config file changes. Is this technique has some serious performance overhead and therefore not preffered in production enviornment? What do people generally prefer - use this method OR simply use DOMConfigurator.configure(fileName) and restart the server after changing the config file?

What does the > rootLogger actually do? , i.e. when do I use the rootLogger? The root logger is just kind of a default handler so that if you don't have any specific logging stuff set up for a particular area of your code there's a place for the messages to go. That's why the root logger is usually set to ERROR or FATAL. Wherever a critical error occurs in your code, you generally want to know about it. Child loggers for particular parts of your code hierarchy then let you set the logging levels and output for particular parts of the functionality you're developing. You can set the root logger to ERROR, so that anything critical that occurs anywhere in your application is logged. You can then set the logging levels for each area that you're developing to different levels so you can see what's going on in there. So let's say, in addition to all of the framework code, you've got two packages in your application, one for business objects and one for the interface. When you're working on the business objects, you can set the logging level to DEBUG and get verbose information about that package, but set the interface logging level to WARN. This means that you'll see a ton of information in the logs about your business objects and only interesting stuff about your interface code. Now you've developed the business objects, change the settings to WARN for your business objects and DEBUG for your interface and get a ton of information about your interface code. This change in the amount and type of information you get from each section is done without changing your code at all, since the filtering is done by just not sending messages to the log when they're sent with Logger.debug() when that's below the logging level you've set. The cool thing is that, if you're suddenly getting weird results from a section of your code, just ratchet down the logging level and you get a bunch more information out of that section. For example, when I've got a bunch of queries that are getting run, I always output the query itself as info and usually output the results (as long as there aren't TOO too many results expected) with debug. That way, if something odd happens, I can see the query and its results without having to step through the debugger slowly, etc. > > That's probably because the stdout is being diverted somewhere.

If you create an appender programmatically and independently of the
properties file, then it will simply work as an additional appender for
that logger and be completely unaffected by the settings in the properties
file. Note that you can do this same thing with the properties file and
in
fact, having just looked at your properties file, I know why, even if
everything else is set properly, you're not getting any output to your
axis.log file. Because you never send anything there. Note that I
removed
all of the appender definitions other than the name and class assignment:
# Set root category priority to INFO and its only appender to CONSOLE.
log4j.rootCategory=INFO, CONSOLE
#log4j.rootCategory=INFO, CONSOLE, LOGFILE
# Set the enterprise logger category to FATAL and its only appender to
CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE
# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
...
# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
...
Basically, you have to understand that loggers and appenders are
completely
independent. Thus, you create an appender called CONSOLE which logs to
the
console (stdout) and an appender called LOGFILE that logs to axis.log.
Great. Create a file and never write anything to it, and see how fast it
fills up. Now you create a logger, a rootCategory logger, one for a
specific package (e.g. your logger for org.apache.axis.enterprise), or
whatever. You can set two main attributes for that logger (there are
others, but don't worry about them for now): the default level for that
logger (INFO for root and FATAL for org.apache.axis.enterprise) and the
appender or APPENDERS to which the logger will write its messages. In
this
file, you're sending everything to the CONSOLE and nothing to the LOGFILE.
What you probably want to do is something like this:
# Set root category priority to INFO and its only appender to CONSOLE.
log4j.rootCategory=INFO, CONSOLE
# Set the enterprise logger category to DEBUG and its appenders to CONSOLE
and LOGFILE
log4j.logger.org.apache.axis.enterprise=DEBUG, CONSOLE, LOGFILE
# Then add the appender defines here
I'm assuming that, because that LOGFILE appender is called axis.log that
you want it set for your Axis stuff, so I added it to that. I also set
the
debug level down to DEBUG instead of FATAL, but really you can set it to
whatever you want.
So now, based on your properties definition, any message of DEBUG level or
higher (i.e. pretty much all messages) sent to the
org.apache.axis.enterprise logger (which will be messages from any class
in
that package or below) will go to the CONSOLE and to the LOGFILE logs.
Any
message of INFO or higher from any other packages will go only to the
CONSOLE.
Then, when you create a programmatic appender and assign it to a logger,
messages sent to that logger will go to your new appender IN ADDITION to
any other appenders already configured for that logger.

Re: Log4j Configuration
I have put log4j.properties under the directory where I have the class

Don't put the properties file itself in the classpath, that won't help
anything. Put the directory or jar file in which the properties file is
stored in the classpath. There should be no folder package structure
either, i.e. if it's /sandbox/classes, then log4j.properties should be in
that directory, with other classes in, e.g.
/sandbox/classes/org/myorg/myproj.
Also, try out that code snippet I sent in my last post to see which

Subject: Re: Log4j Configuration
William,
Two things you can try:
First, add an explicit path to the log file name. So set it to
/var/log/axis/axis.log or /home/you/logs/axis.log or c:/tmp/logs/axis.log
or whatever is appropriate depending on platform, perms, etc. You can
also
do something like ${catalina.home}/logs/axis.log or something like that
too. What's valid is very dependent on your environment, so play around
with that. The default directory for log output is the current directory,
which in the case of a servlet container will usually be the container's
home directory. So, for example, for Tomcat this means your
/usr/local/tomcat or c:\Tomcat or wherever you've got it installed. I'm
not sure where these might go for other containers.
Second, check which log4j.properties file you're loading. I have a little
code snippet here:
http://slapfest.blogspot.com/2005/07/what-version-of-class-or-resource-am-i.html
that you can use to find your log4j.properties. There may be a problem
with that: in the cl.getResource() call, you may need to use
"log4j.properties" rather than "/log4j.properties", but I can't remember.
That'll tell you if your definition is even getting loaded or if your
servlet container is actually getting another log4j config from somewhere
else.
As far as your progammatically created appender, I can tell you why you
won't see any output from there: you're not adding the appender to your
logger. Try something like this:
Logger logger = Logger.getLogger(EchoService.class);
BasicConfigurator.configure();
SimpleLayout layout = new SimpleLayout();
FileAppender appender = new FileAppender(layout,"connectionlog.txt",true);
if (appender != null)
{
logger.addAppender(appender);
}
BTW, as far as the BasicConfigurator stuff? My guess is that that call is
completely unnecessary and could even screw up your configuration (which
is
another possible reason why you might not be seeing any output into your
log files, if it's somehow nuking the default configuration, which
actually
uses PropertyConfigurator).

Re: Log4j Configuration
Don't put the properties file itself in the classpath, that won't help
anything. Put the directory or jar file in which the properties file is
stored in the classpath. There should be no folder package structure
either, i.e. if it's /sandbox/classes, then log4j.properties should be in
that directory, with other classes in, e.g.
/sandbox/classes/org/myorg/myproj.
Also, try out that code snippet I sent in my last post to see which
properties file is actually getting loaded. And remove that
BasicConfigurator call.
And do this all one step at a time so you know which precise change fixed
your problem!

Hi,
I have the following log4j.properties file:

# Set root category priority to INFO and its only appender to CONSOLE.

FileAppender(layout,"connectionlog.txt",true);

Questions:
1. So how does this configuration work, does the java code override the
configuration on properties file?

In the java servlet,
Re: Log4j Configuration
William,
Two things you can try:
First, add an explicit path to the log file name. So set it to
/var/log/axis/axis.log or /home/you/logs/axis.log or c:/tmp/logs/axis.log
or whatever is appropriate depending on platform, perms, etc. You can also
do something like ${catalina.home}/logs/axis.log or something like that
too. What's valid is very dependent on your environment, so play around
with that. The default directory for log output is the current directory,
which in the case of a servlet container will usually be the container's
home directory. So, for example, for Tomcat this means your
/usr/local/tomcat or c:\Tomcat or wherever you've got it installed. I'm
not sure where these might go for other containers.
Second, check which log4j.properties file you're loading. I have a little
code snippet here:
http://slapfest.blogspot.com/2005/07/what-version-of-class-or-resource-am-i.html
that you can use to find your log4j.properties. There may be a problem
with that: in the cl.getResource() call, you may need to use
"log4j.properties" rather than "/log4j.properties", but I can't remember.
That'll tell you if your definition is even getting loaded or if your
servlet container is actually getting another log4j config from somewhere
else.
As far as your progammatically created appender, I can tell you why you
won't see any output from there: you're not adding the appender to your
logger. Try something like this:
Logger logger = Logger.getLogger(EchoService.class);
BasicConfigurator.configure();
SimpleLayout layout = new SimpleLayout();
FileAppender appender = new FileAppender(layout,"connectionlog.txt",true);
if (appender != null)
{
logger.addAppender(appender);
}
BTW, as far as the BasicConfigurator stuff? My guess is that that call is
completely unnecessary and could even screw up your configuration (which is
another possible reason why you might not be seeing any output into your
log files, if it's somehow nuking the default configuration, which actually
uses PropertyConfigurator).

Re: Log4j Configuration
Thanks,
I have included the log4j.properties file in the CLASSPATH and restart
tomcat, but I could not find any log file generated under the entire tomcat
directory, after running the servlet.

Subject: Log4j Configuration
Hi,
I have the following log4j.properties file:
---
# Set root category priority to INFO and its only appender to CONSOLE.
log4j.rootCategory=INFO, CONSOLE
#log4j.rootCategory=INFO, CONSOLE, LOGFILE
# Set the enterprise logger category to FATAL and its only appender to
CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE
# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Threshold=INFO
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=- %m%n
# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=axis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.Threshold=INFO
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%-4r [%t] %-5p %c %x -
%m%n
At the same time, I also have the following lines in my java servlet
Logger logger = Logger.getLogger(EchoService.class);
BasicConfigurator.configure();
SimpleLayout layout = new SimpleLayout();
FileAppender appender = null;
try
{
appender = new
FileAppender(layout,"connectionlog.txt",true);
}
Questions:
1. So how does this configuration work, does the java code override the
configuration on properties file?
2. What does BasicConfigurator do?
3. In propertes file, log4j.appender.LOGFILE.File=axis.log, but I cannot
find this axis.log anywhere after running the servlet.
In the java servlet, I have the line "appender = new
FileAppender(layout,"connectionlog.txt",true);", but I cannot find the
connectionlog.txt file anywhere.
Thanks.
William
