问题 We have a large existing app that has several HttpServlets. These are currently written using log4j logging - except a few of the libs that were written with Java.util.logging uses. I'd REALLY REALLY like to get them all going through the log4j handling and output formatting.

问题 I just encountered a strange error when switching the JDK version of a new Project of mine from 7u45 to 8u20.

问题 I am working on a web application that is running on WildFly and that is using SLF4J and Log4j 2 as logging system. On the Apache pages about Log4j 2 I read about the advantages of using the log4j-web module in a web application (Using Log4j 2 in Web Applications), so I added it and since then WildFly refuses the deployment (that is why I have commented it out in the listing below). So, here is my question: is it advisable to use the log4j-web module with WildFly and if so, how do I set it up
