Log4j.properties in ear

I would like to use log4j in an ear with log4j.properties in the ear. Is there any way to do this with manifest classpath or otherwise?
TIA, Tom

If you are on 8.1 you can put it in EAR/APP-INF/classes. EAR's have

I have put the log4j.properties in the jar file, and in the manifest file for
the jar file write the log4j jar file, the log4j jar file is then in the ear file

Editing log4j.properties file of ear while deploying ear file.

Hi,
Can i edit log4j.properties file of ear while deploying ear file.

>>is MyFolder in the root? else you mite wanna try giving the entire path starting from the root
No the "MyFolder" is not in the root. Normally if we give the file name alone, it will store in a directory. Instead of storing in that directory, i want to have create another subfolder under that directory and storing the file in it. This is my need.

File not found error with log4j.properties

Hi,
I'm writing a web service on weblogic 8.1 with weblogic workshop.I have to use log4j-1.2.7 supplied by client with my application.I cannot write ant script manually.Also I cannot change server start script or cannot put any command line argument when the server starts.
Now I require this logger in my EJB.I have kept log4j.properties in the same path where my EJB's are.But the final ear produced does not contain this log4j.properties and subsequently I get the error "log4j:ERROR Could not read configuration file [log4j.properties]."
Please help me to resolve this problem so that log4j.properties goes with the final .ear file and the ejb code finds the logger.
thanks,
pratim

Hello,

Help to solve problem with packaging log4j in a EAR file

Hi All
i struggle hard to create a EAR composed of EJB JARs and WARs and the programs
in these JARs and WARs use log4j to log msg. Because i want all J2EE apps to have
their own version of log4j library, i package log4j.jar in the EAR file. Below
is my EAR package structure
EJB1.jar
EJB2.jar
SharedUtilities.jar
log4j.jar
log4j.properties
WEBAPP1.war
WEBAPP2.war
META-INF/manifest.mf
For both EJB1.jar and EJB2.jar's META-INF/manifest.mf, there is a below entries
Manifest-Version: 1.0
Class-Path: SharedUtilities.jar log4j.jar
However, my program always hit below runtime error.
[java] Caused by: javax.ejb.TransactionRolledbackLocalException: EJB Exception:
: java.lang.NoClassDefFoundError: org/apache/log4j/PropertyConfigurator
But the program in EJB1.jar and EJB2.jar seem to have no such problem in loading
classes in SharedUtilities.jar. The problem can be eliminated if i put log4j.jar
at system classpath. Can anybody provide me with info on how to package a log4j
library within a EAR package ?
In addition, where should i put the log4j.properties so that it will be at search
path of log4j and automatically loaded by log4j lib
regards
Danny

Hi Slava Imeshev
I am a bit confused about your reply. As said, the log4j.jar was packaged in my
ear file. If the log4j.jar was not packaged in ear file, how come the ejb classloader
can locate it.
Secondly, if log4j.jar is included in system classpath, the ejb also can load
log4j classes by system classloader. No "NoClassDeffound" exception is thrown.

Hi Slava Imeshev
thanks for your response. I am a bit confused about your answer.
i can't understand why u said the classloader COULD loadorg/apache/log4j/PropertyConfigurator.
According to the error msg, it said
" java.lang.NoClassDefFoundError: org/apache/log4j/PropertyConfigurator".
Seemingly,
this class in log4j.jar could not be located. But as i said in lastquestion,
i seemed to have properly
edit the "META-INF/manifest.mf" in EJB1.jar and EJB2.jar to includelog4j.jar
in "Class-path" attribute. And my EJB classes have no problem in loadingclasses
in SharedUtilities.jar. Would u please elaborate on it in more details?
Sure. NoClassDefFoundError means that a DEPENDING class
can not be loaded. If the classloader were not able to load the class
itself, it would give you ClassNotFoundException.
Just make sure that you don't have the same packages in
the ear and in the class path so that you don't have classes
loaded by system classloader trying to load classes loaded
by ejb classloaders.

First, this error means that classloader was able to load

Second, you can package your log4.properties into
log4.jar itself.

Cost involved in changing the code using log4j.properties to log4j.xml

i have finished my application, and it was done in such a way that logging is done using log4j but it was using log4j.properties file.
now i need to change it to log4j.xml. i need to do this at the earliest. so i need to know the cost involved in it?. do i need to change a lot on my app to read the log4j.xml?. In my app there is a function named getProperties, which actually reads the log4j.properties file.
this is the code of that function
public static Properties getProperties(String filename,String path) throws myException
//InputStream is = null;
FileInputStream is=null;
        Properties props = new Properties();
        //ClassLoader classLoader = ResourceUtil.class.getClassLoader();
        //is = classLoader.getResourceAsStream(filename);
        File catalinaHome = new File(System.getProperty("catalina.home"));
        try {
is=new
FileInputStream(catalinaHome.getCanonicalFile()+path + filename);
} catch (IOException e) {
        if(is == null)
            String message = "Cannot locate property file " + filename + " in the classpath";
            log.error(message);

            catch(Throwable t)
                t.printStackTrace();
        if(props.isEmpty())
            String message = "No properties are defined in " + filename;
            log.error(message);
        throw new myException(message);

1. Restructure log4j.properties into log4j.xml.
thats done
2. Move log4j.xml into a directory that's in the
classpath.
actually i donot understand what does it mean to move in a directory thats in classpath means. i have to use logging in my webapplication running in tomcat. and my log4j.xml has to reside in catalina.home/properties/. My log4j.properties have been residing here and it had worked well woth the previous function. Now what i did is placed the log4j.xml under properties folder. Now tell me what modifications should i make in the above code.
3. Remove any code that explicitly configures log4j
(i.e. the initialize() method) because log4j will
configure itself from any properties file it finds in
the classpath, automatically, the first time it is
called.I prefer not remvoing this function as this function is being called in many of my classes... and we don't have time to edit all...
please help... and excuse me if i asked some blunders.!!!

Configuring directory path for fileappender in log4j.properties

I want to write log data to a file where the directory path of the file should be picked from a unix environmental variable. How can you configure this in log4j.properties?
log4j.rootLogger=INFO, A
# A is set to be a FileAppender.
log4j.appender.A=org.apache.log4j.FileAppender
# A uses PatternLayout.
log4j.appender.A.File=$UNIX_ENV_VARIABLE/A.log <= This is what I want. The dir path should be picked from some env path
log4j.appender.A.layout=org.apache.log4j.PatternLayout
log4j.appender.A.layout.ConversionPattern=%d{HH:mm:ss,SSS} [%t] %-5p %c %x - %m%n
Or if this should be done in code, then please guide me on that.
Thanks in advance

Hi,
i am facing one problem,

A question about log4j.properties

Normally I put the log4j.properties inside my web-application such as under WEB-INF. So it will be packaged into the WAR.
But now I want to take it outside of the WAR and put it under a dir and furthermore I change its name to "myLog4j.log4j.properties". This has two advantages:
1.
One can change the contents without opent the WAR.
2.
Under this dir the other projects can put their xxx.log4j.properties so they can be managed easily.
But I don't know where should I put this file and how to configure the server sothat the server can find this file and my program can write all the log infos into the log-file defined in the "myLog4j.log4j.properties".
Can someone help?
Regards

Actually file log4j.properties should be in the classpath, that classloader could see it. Add the path to file into CLASSPATH.
Thanks

Log4j.properties or log4j.xml Not Reading

Hello,
I am trying to use log4j in jsp.
I have added log4j.properties in /WEB-INF/log4j.properties.
And in jsp page, I added like
Logger logger = Logger.getLogger("test1.jsp");When I run jsp page, I get
log4j:WARN No appenders could be found for logger (test1.jsp).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.Is this the right place to keep log4j.properties file? Does java classes can read if I put under /WEB-INF folder?
If I am using log4j.xml where to keep this file?
Regards

Here is what I figured:
add properties to the workspace/WEIB-INF/directory.xml and then read them from the PAPI code using
String myProp = DirectoryConfigurationManager.getRuntime("default").getConfigurationProperty("categoryName", "propKey");

Problem with log4j.properties and level DEBUG

Hi,
I need some log4j help.
I create 2 different appenders in the log4j.properties file
and it works.
This is my complete log4j.properties:
log4j.logger.log1=DEBUG, log1
log4j.logger.log2=DEBUG, log2
log4j.appender.log1=org.apache.log4j.DailyRollingFileAppender
log4j.appender.log1.File=${StandardLogPath}
log4j.appender.log1.DatePattern='.'yyyy-MM-dd
log4j.appender.log1.Append=true
#log4j.appender.log1.Threshold=DEBUG
log4j.appender.log1.layout=org.apache.log4j.PatternLayout
log4j.appender.log1.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss} [%-5p] %-25c{1} %m%n
log4j.appender.log2=org.apache.log4j.DailyRollingFileAppender
log4j.appender.log2.File=${StandardLogQueryPath}
log4j.appender.log2.DatePattern='.'yyyy-MM-dd
log4j.appender.log2.Append=true
log4j.appender.log2.layout=org.apache.log4j.PatternLayout
log4j.appender.log2.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss} [%-5p] %-25c{1} %m%nAnd here's my logging code:
import org.apache.log4j.Logger;
Logger log = Logger.getLogger("log1");
Logger logQuery = Logger.getLogger("log2");
log.debug("loggerDebug");
logQuery.debug("loggerDebug");
log.info("loggerInfo");
logQuery.info("loggerInfo");The problem is that "loggerDebug" is not written to all appenders (only "loggerInfo").
In fact if I print:
System.out.println( log.getEffectiveLevel().toString() );result that the level is INFO and I known that if level is INFO then DEBUG is disable.
But why the level is INFO????
Someone can suggest me a solution?
Thank you very much

You're so over-sensitive you: when an OP doesn't respond anymore
to your last reply it implies that you've solved the problem and
(implicitly) that the OP is very grateful to you. Why do you always
have to be so explicit about matters? ;-)
Because I'm not one of those Dutch people ;-)Yes, that's us, the Dutch: mysteriously smiling and keeping silent all the
time. That's why they call us the Asians of Western Europe ;-)
ps. There are nice exception to the rule sometimes though.
Yes, and unfortunately they do seem to be the exception rather than
the rule. It would be nice to catch one a bit more often.True; that's the internet generation: grab all the information that you can
and don't give a f*ck about the guy who supplied the information. It's sad
indeed.
Maybe we should start a support group where we could thank each
other now and then 'on behalf' of those little spoiled brats and complain
about all those bad manners nowadays ;-)
kind regards,

JMS Appender in log4j.properties ??

Hie Experts,
I have setup a logging mechanism to log messages asynchronously using JMS queue.
Currently, I am doing this as a call to a method.
Inside the method, I am
- creating a JNDI context,
- retrieve queue connection factory,
- create a queue session, create a queue sender and
- associate to the retrieved queue.
- Finally I send the message and close the queue.
I do not think that this is the best strategy because:
1. Queue gets initialized for all logging (making it slower)
2. I believe that there must be a simpler way such as adding a JMS appender in log4j.properties
Please advise if there is a better strategy.
Thanks,
V Chitkara

Hi Vishal,
You are correct in your assumption that there is a simpler way to perform logging using JMS.
The Log4J project already contains a JMS appender. Take a look at this page:
http://logging.apache.org/log4j/docs/manual.html
And search it for "JMS".
Hope this helps,

How to load log4j.properties

how to load log4j.properties file in my java code ?
i have put log4j.properties in c:\property\log4j.properties directory.
how do i load this properties file ?

Normally you don't have to load it explicitely at
all. Just place it in your classpath and use log4j,
it should be loaded automagically.so, at run time i should use
java -classpath .;c:\property\log4j.properties;c:\log4j.jar; MyClass
is this the syntax ?

WS32 - proper location for log4j.properties?

Greetings,
I am running WS3.2 and I have a log4j.properties file located in /resources/* within the IDE.
As long as I manually copy the file into the "java/classes" directory the file is picked up at runtime.
Ideally, Workshop should be automagically grabbing the properties file and placing it on the classpath when I "run" the application.
Is there a workaround for this (besides the manual copy)?
Is this a defect or am I doing something quite stupid?
much thks!

Ok - I've figured this one out.
The Log4j.properties file needs to reside at:
web/WEB-INF/src/java.
Workshop 3.2 DOES copy the file over to the classes director but since I had it in a subfolder called "resources" it wasn't being picked up.

How to disable error log in trace.out file , i want to error log only in error.out file, but acctualy error log still appears in trace.out.

avoid setting Threshold. instead use a specific logger in your class for errors:
public final static Logger sysErrLog = Logger.getLogger("SystemError");
and configure this logger in the log4j.properties:
log4j.logger.SystemError=ERROR, SystemErrorLogFile
log4j.additivity.SystemError=false
log4j.appender.SystemErrorLogFile=org.apache.log4j.RollingFileAppender
log4j.appender.SystemErrorLogFile.File=${LogDir}/systemerror.log
log4j.appender.SystemErrorLogFile.append=true
log4j.appender.SystemErrorLogFile.layout=org.apache.log4j.PatternLayout
log4j.appender.SystemErrorLogFile.layout.ConversionPattern=%d{ISO8601} %c{2} - %m%n
log4j.appender.SystemErrorLogFile.MaxFileSize=1000KB
log4j.appender.SystemErrorLogFile.MaxBackupIndex=3

Log4j.properties location

Hello,
I want my web application uses a log4j.properties file located in a directory outside Tomcat, in /var/app/conf/.
I'm using the PropertyConfigurator to configure log4j. If I put log4j.properties in the WEB-INF/classes directory all works fine, but if I put it in the "external" directory works but I get these warnings:
log4j:WARN No appenders could be found for logger (org.apache.catalina.startup.TldConfig).
log4j:WARN No appenders could be found for logger (org.apache.commons.digester.Digester.sax).
How could I avoid these warnings?
Thanks!

I am putting log4j.properties file in same folder
where the java class file is, it's working fine. If
i'm puting it in some different folder (folder is on
class path) it's giving the proper output as log file
but throwing exception at console as:I don't think it's the location of the java class, but rather
where you are when you run the program. I'm running
junit tests from within eclipse, and need to put the file
one directory above my "com" directory. From the
command line, the properties file just needs to be in
the current directory. Perhaps using a fully qualified
path name will solve your problem; no matter where
you run the program, the file will be found. This
assumes you have access to a fully qualified location
(probably bad). Best to determine from where the
program will be run, and place the file in a relative
directory off of that (perhaps at deploy time).
Cheers,
Brian

Log4j.properties with OAF R12

I am writing OAF R12 components that integrate/extend existing R12 pages.
I need to deploy a log4j.properties file for logging. I have a dependent jar file that uses log4j. This file is usually placed on the classpath in WEB-INF/classes for a servlet application.
Where should I place this log4j.properties file so that the OAF R12 container (oc4j) reads this file when processing. I tried to add it to the CLASSPATH. I edited orion_application_xml_1013.tmp and placed the log4j.properties in $JAVA_TOP and added lines for the <library path> as
<library path="$JAVA_TOP/log4j.properties" /> or
<library path="%s_javatop%/log4j.properties" />
and restarted the server.
However, the log file defined in log4j.properties is not created when running the OAF framework and exercising the integrated code that includes log4j logging.
What is the best way to integrate this properties file?
Thanks,
Ken

gday Ken --
If you are OAF R12 wouldn't there be an Oracle standard for logging you should be using? I'd be asking the OAF team for more details.
Then I'd ask whether using log4j is worth the extra effort over using the Java standard logging API -- the container itself is using Java standard logging API, for which we have the ability to dynamically adjust log levels, view the logs, etc.
Here are some links to some notes I wrote up recently on using log4j with OC4J (and also using Java standard logging API) :
