log4j.appender.Logfile.layout.ConversionPattern =%-5p|%-80m|%d%n
for these two different file appenders , i want to instantiate two different loggers so how can i do it
at present moment i am instantiating log like this
String callingClassName = Thread.currentThread().getStackTrace()[2].getClass().getCanonicalName();
return Logger.getLogger(callingClassName);

log4j.logger.myFile1=debug,file
log4j.logger.myFile2=debug,Logfilein the Java Code you have to select one or the other logger:Logger fl1= Logger.getLogger("myFile1");// loggs to {qtl.log.operation}
Logger fl2= Logger.getLogger("myFile2"); // loggs to ${qtl.log.application}bye

Log4j: Logging Errors(No appenders could be found for logger)

hi,
i used logging in my java application. i placed log4j.jar and log4j.xml file paths
given in classpath.
i am getting 2 warning Messages. Those are as follows
Log4j:WARN. No appenders could be found for logger (Myclass.class)
Log4j:WARN. Use Log4j System Properly.
Here is what i done
log4j.xml is external configuration file. I specified Appender and layout
information in this.
Here is log4j.xml content...
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="appender" class="org.apache.log4j.FileAppender">
<param name="File" value="C:\LOG\log.txt"/>
<param name="Append" value="false"/>
<layout class="org.apache.log4j.SimpleLayout"/>
</appender>
<root>
<priority value ="INFO"/>
<appender-ref ref="appender"/>
</root>
</log4j:configuration>
I specified appender and layout in log4j.xml file and placed log4j.xml file in
classpath.
How can i solve this problem?. Please help me.

Ok. I'm no log4j expert, but if you try to get a logger called Myclass.class and have not defined one in your xml file, there's a problem? Look at my xml file below, especially the category tag. Instead of putting "All" for the name, you would put "Myclass.class".
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

How do I specify the location of log4j.log?

I want to create the log4j.log file in "C:\TEMP\" for Windows and "/tmp/" for linux. Is there anyway that I can do to that?
Here is what I currently have for my log4j.properties:
# SET ROOT CATEGORY PRIORITY TO DEBUG AND ONLY APPENDER TO A1, C1, R
log4j.rootCategory=DEBUG, C1, R
log4j.appender.C1=org.apache.log4j.ConsoleAppender
log4j.appender.C1.layout=org.apache.log4j.PatternLayout
log4j.appender.C1.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n
log4j.appender.R=org.apache.log4j.RollingFileAppender
#Create the file in Windows
#log4j.appender.R.File=C://TEMP//log4j.log
#Create the file in Linux
log4j.appender.R.File=/tmp/log4j.log
log4j.appender.R.MaxFileSize=15000KB
# KEEP FIVE BACKUP FILES
log4j.appender.R.MaxBackupIndex=5
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n
#log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%nThank You,
Chris

Here is another configuration file that uses multiple appenders.
log4j.rootLogger=debug, stdout, R
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
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=example.log
log4j.appender.R.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R.MaxBackupIndex=1
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%nIn addition, as the root logger has been allocated a second appender, output will also be directed to the example.log file. This file will be rolled over when it reaches 100KB. When roll-over occurs, the old version of example.log is automatically moved to example.log.1.

Integrating log4j logging

I want an EJB to wrap a library which uses apache log4j logging. log4j has
an adapter to log to different outputs. Has anyone integrated log4j with
WebLogic's logging?
Thanks,
Gary

If you use the apache commons API, then it will automatically pick up log4j if it's on the class path. Otherwise it will use the logger built into the standard library.
The tiresome part is actually getting the configuration file set up and accessed. All you need in the code is something like:
public class A {
private static Log log = LogFactory.getLog(A.class);
log.info("This is a log message");
}You'll generally need a -D parameter to set the logger to point at the appropriate configuration file.
If you use the standard libraray logger then you can actually change the logger settings dynamically with jconsole.

How to configur log4j logging for weblogic 10.1

Hi,
I am tried to set log4j logging for my application running in weblogic 10.1. I set a log4j.properties file and loaded the properties by a servlet. Where its load the properties files and configure it by PropertyConfigurator.
The same logic has worked out in websphere. But in weblogic, it is not working. I set the server logging and domain logging to Log4j in Admin console. Now it is writing all the log statements.
If i write a property for a package to Error level and root level is Debug. Its not working, all debug statements are getting written.
Can you please tell me the steps to configure log4j logging in weblogic 10.1.
Thanks & Regards,
Nasrin.N

Did you manage to get this working?
If yes ... what did you do?
I am having the same problem implementing commons-logging with log4j

FF logs in different location ( Not FF tables)

Hi
Can we have FF logs in different location other than the backend tables? My client wants to have the sensitive FI and HR data logs maybe in a share restricted network drive / folder. Is this worth it?
If anyone has done this, please share your experience and best recommended approach

Hi Robert,
Per my knowledge No.
not possible, SPM in frontend (JAVA stack) is used only for reporting purpose, core functionality is still in the backend (R/3)
you need to
- control access to all this data like frontend Log Report, emails, backend tables..... so on
- my suggestion will be not to use FF for HR purpose
- do custom development
regards,
Surpreet

If you have the EM (Enterprise Manager) installed on your stand alone WLS (which you should) you can select the managed server your app is running on, select the 'Log Configuration' menu and you should see almost the same representation an in jdev.

Oracle Daignostic Logging Vs Log4j logging

Which type of logging is advisable/best for Oracle SOA applications? Oracle Daignostic Logging (ODL) or Log4j logging ?
Thanks
Sree

We have found it better to use ODL logging because of the support of tracking logs using the ECID. This allows logs across multiple components to be followed. Also the ODL logs can be searched and viewed through EM or the plain text log files and can be exported and viewed in JDeveloper offline as well.

You should find what you need on the Log4j Project Page.

Log4j / Way to use any appender to get log4j logs into java logger logs?

Hi,
I've an older component, this use log4j.
So I wonder if there any way to get log, logged by Log4J, into Java Logger logs?
Thanks a lot!

Thanks a lot, but this is not what i ment.
I use glassfish. Glassfish uses for all log the Java Logger.
My problem ist, that I have a library, that uses Log4J for logging.
My current workaround is, to log all Log4J logs to console.
Glassfish collect all "sysouts" and write them into the jave logger log file.
But I wonder, if there is another way. I can't find any JavaLoggerAppender or something else.

Configure log4j to write to different log files conditionally

Hi folks,
Is there is way log4j could be configured to write to multiple log files conditionally? Let me try to explain what i am trying to do.
I have two classes DatabaseChecker and FTPChecker extends Checker class. Within Checker class, there is a method logTestResult(CheckerType c, boolean isFailed, int retry, int isMaxRetryExceeded). Depending on the CheckerType(database or FTP), I need to write log outputs to different files (dbchecker.log or ftpchecker.log). How do i configure log4j to do this?
I've seen how to configure log4j based on classes from different package, but not sure on this one. Any clue would be much appreciated.
