log4j - ear file - jboss6

[Yaron Rel]

Hi,
It seams that whatever i do I keep getting the following error in the server.log:
Is there any normal working tutorial or example for integrating ear file with log4j in jboss?

It happens when I call from junit a remote stateless bean that has the following logger:

decleration:
private static Logger logger = Logger.getLogger(MyDao.class);
usage in class:
logger.info("in my dao");

here is my pom dependency of pom.xml:
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.14</version>
</dependency>

here is my log4j.properties:
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
log4j.rootLogger=debug, stdout

Yaron, welcome to Java Ranch!

Looks like you are packaging the log4j.jar file into your app, which results in classloader issues like the one you are seeing. Change your pom.xml to indicate that the log4j.jar is not needed to be packaged with your app (add a <scope> entry):

<dependency>
  <groupId>log4j</groupId>
  <artifactId>log4j</artifactId>
  <version>1.2.14</version>
  <scope>provided</scope>
</dependency>

P.S. Please use the code tags when posting source code - makes it much easier to read.
