Log4j error

Hi Team,
I have seeing this error in our weblogic engine logs. Also the logs are not getting updated due to below error.
Looks like there is some issues with the configuration.
Let me know should you require any further information.
Any help on this will be highly apprecited.

Hi,
Can you please provide the error.
Also would like to know whether you have added the Log4J component additionally to the project or are utilising the logging provided within the BPM?

Log4j Error while deploying application in weblogic

Hi All,
I am deploying one web application in weblogic, which uses log4j jar file to write logs. But ahile deploying it shows the following error in weblogic console.
Please help on this.
log4j:ERROR A "org.apache.log4j.RollingFileAppender" object is not assignable to a "org.apache.log4j.Appender" variable.
log4j:ERROR The class "org.apache.log4j.Appender" was loaded by
log4j:ERROR [sun.misc.Launcher$AppClassLoader@169e11] whereas object of type
log4j:ERROR "org.apache.log4j.RollingFileAppender" was loaded by [weblogic.utils.classloaders.ChangeAwareClassLoader@169baee finder: weblogic.utils.classloaders.CodeGenClassFinder@44c4a4 annotation: Server@Server].
log4j:ERROR Could not instantiate appender named "log".
log4j:WARN No appenders could be found for logger (com.servion.citigreece.util.LoggerUtil).
log4j:WARN Please initialize the log4j system properly.
Thanks & Regards,
Raja Mohammed.

Seems like a classic case of having log4j both in the war and the app-server's own libraries.
At least in JBoss this would be fixed by making sure that common/lib's log4j jar is being used (or alternatively, removing that and using the one in the war, but that might not go as smooth).

Log4j error when starting Tomcat

Hi. I've just installed Tomcat on my desktop PC and when I try starting it up (startup.bat), I get the following warning:
log4j:ERROR No appenders could be found for category (org.apache.struts.util.PropertyMessageResources).
log4j:ERROR Please initialize the log4j system properly.
I can still view my STRUTS app, but I'm curious to know why this problem is occuring and how it can be fixed.
Thanks

Log4j is fail-stop meaning that if the log4j system is not initialized properly, attempts to log will throw up this message initially. There is nothing 'broken' with Tomcat or logging, and no 'error' is occuring other than the fact that some of the code is trying to do logging but the logging has not been initialized properly.
If you want to eliminate this message, you will need to provide a log4j configuration file. There probably already is one somewhere; it just isn't being read when the system is started.

Log4J Error Message

Hello,
I have this code:

emailAppender.setTo(buildEmailRecieversList(to));
logger.log(Level.ALL,message); //message is an argument to the functionWhen I run it, I get an error:

Can somebody please explain me why this error is happening and how to fix it?
Thanks.

Double post
http://forum.java.sun.com/thread.jspa?threadID=685425&

Sorry...

Log4j:ERROR Message object not configured.

while trying to use the SMTPAppender i got this message:
log4j:ERROR Message object not configured.
any idea?
thank you

It is unfortunte that this tops the Google serach
result for the subject text. It is message like this
that really pollutes all the good information that
are found in the web space. Message like this not
only perpetuates the "anti-social geek, I'm God and
you're not" stereotype, but also alienates the next
generation of aspired developers that this country is
so in need of.Did you register an account just to insult a pretty well-dedicated group of volunteers here? These people offer to help people they don't know with absolutely no benefit to themselves except to further the process of learning. Maybe there' s a warm fuzzy stemming from the fact that the person whose question was answered might have learned something.
If this is the type of asshat developer you would like to foster through the IT world, then you can try to put up with these people. People who are unwilling to communicate their problems do not deserve to have them solved. People who are simply attempting to skate by and be spoonfed through what's left of their mediocre careers can go elsewhere for help.
Thank you for your answer, and I admire that you posted here after you solved your own problem. Just leave out the cheeky, holier-than-thou diatribe next time. Go to Javaranch if you want to chat about Java and have your hand held while you bumble around.

Log4j:ERROR Could not instantiate configurator

I use
-Dlog4j.configuratorClass=mypackage.Log4jConfigurator
java option in startWeblogic command file
to read changes in log4j-config.xml.
After that I have in console.log
og4j:ERROR A "mypackage.Log4jConfigurator" object is not assignable to a "org.apache.log4j.spi.Configurator" variable.
log4j:ERROR The class "org.apache.log4j.spi.Configurator" was loaded by

log4j:ERROR "mypackage.Log4jConfigurator" was loaded by [sun.misc.Launcher$AppClassLoader@12498b5].
log4j:ERROR Could not instantiate configurator [mypackage.Log4jConfigurator].
Could anybody help?

Did you get a resolution? I have a similar problem with a different object, org.apache.log4j.spi.TriggeringEventEvaluator, which has been loaded by the Weblogic consoleapp. I am running in a standalone server configuration -- admin and application server are the same. Also, using exploded directories.
Is there a way to prevent the WebLogic classloader from loading its version from the consoleapp?

But Tomcat still raise above error? Why? I am puzzled with it for a long time! Anybody meet with above question? Any idea will be appreciated!

Well, classes12.zip is a fairly old driver, especially for JDK 1.5, and even for Oracle 9. So, I would first suggest visiting Oracle's JDBC driver download sie.
If that fails, please post the code you are using to connect to your database (please do not post the real domain or your user name or password). :^)

Log4j:ERROR Failed to rename [../logs/avaluos] to [../logs/avaluos.2004-07-

Hello,
I have a webapp deployed in Tomcat on Windows 2000 server, I configured log4j using a DailyRollingFileAppender in the following way:
# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, A1,DAILY
#Daily log file
log4j.appender.DAILY=org.apache.log4j.DailyRollingFileAppender
#A log file for each day. Better for manageability
log4j.appender.DAILY.DatePattern='.'yyyy-MM-dd'.log'
#The file for each day will be named avaluos+DatePattern+.log
log4j.appender.DAILY.File=../logs/avaluos
#Layout configured for this appender
log4j.appender.DAILY.layout=org.apache.log4j.PatternLayout
#The pattern used to log messages
log4j.appender.DAILY.layout.ConversionPattern=[%d{HH\:mm\:ss,SSS}] %-5p %c{3} - %m%n
but every time log4j tries to roll the file, and therefore renaming, it fails with the message "log4j:ERROR Failed to rename [../logs/avaluos] to [../logs/avaluos.2004-07-29.log].", loosing the log of the day before!!!!
I watch on other forums and someone suggested to try out the same pattern adding the minutes, because sometimes this error is present just the first time. I did so, but the error is still present. I read in other place that problem can arise from window's file locking, but nor they explain it well, neither they gave a solution.
Please HELP!!!
Thanks in advance, Alfredo Ledezma

By the way, some time before (1 month or so) the same configuration worked.... so I don't know what's messing around :-(

Log4j error while deploying EJB 3.0 in weblogic 10

If i remove the "set JAVA_OPTIONS=%JAVA_OPTIONS% -Dlog4j.configuration=log4j.properties" from the weblogic statrup script and install the EAR it will be installed , but the logger is not initialized.
If the option "set JAVA_OPTIONS=%JAVA_OPTIONS% -Dlog4j.configuration=log4j.properties" added to the startup script and i deployed the OLD EJB 2.0 app , it is installed successfully, but it didnt let me deploy EJB 3.0 app.
I am hitting my head around it for a day now, no success so far..
Please provide you suggestions , thanks a lot to all in advance.
Thanks
Sachin

Does the ejbCreate() method of the com.package.ejbimpl.RemoteServicesEjb class have an exception on it's throws clause that is not present on the ejbCreate() method of your home interface? If so, does the error go away if you add the exception to the home's ejbCreate() method? In general, you want checked exceptions in a throws clause to match between the interface declaration of the method and the implementation of the method on the bean class.

Log4J-Error + Unexpected Database-Connector-Error

Hello!
I am trying to integrate a Report into an existing Java Eclipse-Project usind Crystal Reports for Eclipse.
To do this I am modifying the example program which comes together with the installation. I am trying to pass the data to the report directly via a POJO using the call
CRJavaHelper.passPOJO(...)
Now, when I try to open the report I get the following error:
log4j:WARN No appenders could be found for logger (com.businessobjects.reports.sdk.JRCCommunicationAdapter).
log4j:WARN Please initialize the log4j system properly.
Unerwarteter Datenbank-Connector-Fehler
(The last line would be "Unexpected Database-Connector-Error" in english.)
What am I doing wrong? I included log4j.jar into the build path of the project.
Thanx for your help!
UPDATE: Most errors are sitting 50cm in front of the screen. Dumb error on my side. Fixed it and it's working.
Edited by: QSOTech on May 18, 2009 1:33 PM

Error is fixed.
I created the report in Eclipse and used a Plain Old Java Object (POJO) as datasource. No other Database.
The problem was that the Object wasn't instanciated properly.

Log4j error on exceution

Hi,
I have an application that uses log4j for logging purpose. I designed this is Windows using eclipse. So, what happened was I placed the "log4j.properties" file in the <package name>/bin/ folder and the program could read the log4j.properties file. With this I was able to successfully run the application on Windows.
Now I need to run this application on a Unix machine, and I have packaged my application as a jar. Also I have included the log4j.jar file in the proper folders and have made sure that my application is able to access this jar when i try to run.
I am using a common class by the name "LogCreation" that contains the PropertyConfigurator part. So, this is the class that I use across all my Java files to generate log. The code in that file is as below:
package ftpScheduler;
* Class to create the Logger and initialize the Properties file
* @author user_name
import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
public class LogCreation {
      * Constructor for LogCreation class to assign the properties file
     public LogCreation(){
          PropertyConfigurator.configure("/home/uchebolu/FTPSchedulerApp/log4j.properties");
     static Logger cmnLogger = Logger.getLogger(LogCreation.class.getName());
}So, now I am getting the following error:
log4j:WARN No appenders could be found for logger (ftpScheduler.LogCreation).
log4j:WARN Please initialize the log4j system properly.
My log4j.properties file is as follows:
#The root logger is assigned priority level DEBUG and an appender
# named myAppender.
log4j.rootLogger=INFO, logAppender
# log4j.additivity.rootLogger=false
# The appender's type specified as FileAppender, i.e. log output
# written to a file.
# The appender is assigned a layout SimpleLayout.
# SimpleLayout will include only priority level of the log
# statement and the log statement itself in log output.
log4j.appender.logAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logAppender.File=${user.home}/logs/FTPSChedulerLog/logfile.log
log4j.appender.logAppender.datePattern='.'yyyy-MM-dd
log4j.appender.logAppender.append=true
log4j.appender.logAppender.ImmediateFlush=true
log4j.appender.logAppender.Threshold=ERROR
log4j.appender.logAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.logAppender.layout.ConversionPattern=%-5p %d{ISO8601} [%t] - %m%nInspite of mentioning the Appender I seem to getting an error. Can anyone Please help me out. Thanks in advance!!

static Logger cmnLogger =Logger.getLogger(LogCreation.class.getName());
You retrieve the logger before your Constructor iscalled thus Log4J is not >initialized.

Hi Andi,
I am sorry but I could not understand this. BecauseI need to make a call to getLogger, >which will will
in turn call the consructor. There is no other way I
could do it..:-(. I dont think >there is any other
way out other than making a call using getLogger.
I don't see the point where your Constructor is
called.
Because I need to make a call to getLogger, whichwill will in turn call the consructor.
Why should this happen ? This would only be true if
your LogCreation class were a LogFactory andyou have configured Log4J to use your LogFactory
instead of the default LogFactory.
one possibility would be
public class LogCreation {
static Logger cmnLogger;
     static {
PropertyConfigurator.configure(
"/home/uchebolu/FTPSchedulerApp/log4j.properties");
cmnLogger =
ger = Logger.getLogger(LogCreation.class);
// or
static {
System.getProperties().put("log4j.configuration",
"/home/uchebolu/FTPSchedulerApp/log4j.properties"
ies" ) ;
cmnLogger =
gger = Logger.getLogger(LogCreation.class);
}or set the Systemproperty
"-Dlog4j.configuration=/home/uchebolu/FTPSchedulerApp
/log4j.properties" at the commandline.

Hi Andi,
Thanks a lot, for that explanation. Now I understand where I went wrong in my understanding.
So, in my java class, though I had given the entire path for the log4j.properties file, it was not even read. Because I was using the default name log4j.properties, once I placed the file in the CLASSPATH, the JVM started recognizing the file. And the only line of code that was being executed was :
static Logger cmnLogger = Logger.getLogger(LogCreation.class.getName());So, if I put the PropertyConfigurator.configure() part also in a static block it will get invoked before the cmnLogger object is instantiated.
Hope this time I got it right!
Thank you once again Andi.

Log4j:ERROR No appenders could be found for category

Log not og

In your top level class did you include a configurator?
This is the minimum requirement:
import org.apache.log4j.BasicConfigurator;
BasicConfigurator.configure();Calling a configurator only needs to be done in the initialization of the application (not of each class), prior to the first call to log a message.
I am responding to this because this thread about log4j got me thinging about a logging API and then to compare log4j to the Logger classes in 1.4. I started to use log4j and recalled that an error I saw was similar to your initial post.
