Defining which factory to use
Now you must tell XWork/Struts2 to use your implementation, just define system property like below:
-Dxwork.loggerFactory=com.demo.MyLoggerFactory
you can use the same to explicit tell the framework which implementation to use and don't depend on class discovery, eg.:
-Dxwork.loggerFactory=com.opensymphony.xwork2.util.logging.slf4j.Slf4jLoggerFactory
will enable Slf4j even if there is commons-logging on classpath available (commons-logging is the first LoggerFactory to look for).
