Jboss Deployment Failure - ClassNotFoundException
<p>I encountered ClassNotFoundException during deploying a war file to my jboss server. I think it is related to log4j since it returns "Deployment error processing SCI for JAR: log4j-web-2.2.jar" error. However, the web app works properly on apache tomcat on eclipse. I have no idea of how to solve it. Thank you in advance.</p>
