Jdeveloper, WLS and Log4j logging

Question

All,
I want to route all the ADF application log messages to a log file using log4j.
I have created a log4j.properties and put in the ViewController/src folder. The application finds that config file, and produces the desired output - so far, so good.
Now I would like to route all the WLS logging using log4j.
To first try it, I've opened the integrated WLS console, and set, under server/logging, that the log implementation uses log4j instead of jdk. I have also checked the "redirect stdout", "redirect stderr", and "logging bridge" check boxes.
I've also:
- included the wllog4j.jar and log4j-1.2.16.jar in the classpath (by editing the /home/semar/Oracle/Middleware/wlserver_10.3/common/bin/commEnv.sh file).
- put a copy of log4j.properties also in the WLS path - which is, in my case: /home/semar/Oracle/Middleware/wlserver_10.3/server/bin
- put the path of the log4j.properties in the WLS CLASSPATH (by editing the /home/semar/Oracle/Middleware/wlserver_10.3/common/bin/commEnv.sh file)
I've then re-started the integrated wls, and now what happens is:
- the log appender for my application is no more found (log4j complains that the appender is not configured)
- no log file is produced/updated
Am I missing something obvious here ? Where should I put the log4j.properties then ? Are other extra tasks I should perform, in order to get all the ADF and WLS logging routed through log4j, and configured using a single log4j property file ?
I'm using WLS 10.3.5.0 and Jdeveloper 11g rel 2 11.1.2.1.0, running on a Linux OpenSuse 11.4

Still no joy.
I have put the two JARs + log4j.properties into domain_root/lib folder.
I have also modified the startWeblogic.sh by adding the following:
JAVA_VM="${JAVA_VM} -Dlog4j.configuration=${DOMAIN_HOME}/lib/log4j.properties"
export JAVA_VM
Both the .jar files and the log4j.properties are in the classpath and in the java options of the WLS starting log.
In my application I have:
package logging;
import org.apache.log4j.Logger;
import...
public class loggingBean {
/* Get actual class name to be printed on */
Logger log = Logger.getLogger(loggingBean.class.getName());
public loggingBean () {
System.out.println("hello from loggingBean constructor");
//_logger.info("Creating a new instance");
log.debug("Hello this is a debug message");
log.info("Hello this is an info message");
In the log4j.properties I have:
# Define the root logger with appender file
log = /tmp
log4j.rootLogger = DEBUG, FILE
# Define the file appender
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=${log}/log.out
# Define the layout for file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern=%m%n
# end of the log4j.properties
And in the standard log file (nohup.out since I start the server with it):
<11.04.2012 14:56 Uhr MESZ> <Notice> <Stdout> <BEA-000000> <hello from loggingBean constructor>
<11.04.2012 14:56 Uhr MESZ> <Notice> <StdErr> <BEA-000000> <log4j:WARN No appenders could be found for logger (logging.loggingBean).>
<11.04.2012 14:56 Uhr MESZ> <Notice> <StdErr> <BEA-000000> <log4j:WARN Please initialize the log4j system properly.>
<11.04.2012 14:56 Uhr MESZ> <Notice> <StdErr> <BEA-000000> <log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.>
The file /tmp/log.out does not exist.
Any thought ?
