I do not have CLASSPATH env variable set up, I think this is something to do with the classloading Yes you are correct, we got two options 1) delete the log4j from the other projects 2) update the jboss log4j with other projects even though above works, It doent look nice, the best way is how you manage the log4j classloading in a isolated way, I believe jboss will work on this, so that the installation is straight forward without any impacts from the other loaded jars.
