Hi! I've just upgraded to struts 2.5 and faced an issue with my existing logging configuration.
The error appears at startup: "ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...". I want to use slf4j+logback, so I configured the system property, as seen at docs: xwork.loggerFactory=com.opensymphony.xwork2.util.logging.slf4j.Slf4jLoggerFactory But I'm still getting that error. I know that a change was made and is related to it (WW-4504), but... Thanks in advance!
