Hi, Log4j is a logging toolkit from Apache. Its home page and docs are at http://logging.apache.org/log4j. It is used by many applications and libraries directly, and by many applications and libraries via commons-logging (http://jakarta.apache.org/commons/logging). If commons-logging finds log4j on the classpath, log4j is used for logging.
The message you got means something in your code (or more likely, the Axis or Slide code) made a log4j logging statement before log4j was configured. This is not a fatal error. It means you're losing logging statements until you configure log4j. A good way to configure log4j is to create a properties files, log4j.properties, and put it in the WEB-INF/classes directory of your web application. The free short log4j manual (http://logging.apache.org/log4j/docs/manual.html) contains examples of configuration files. There are many additional examples available via a simple Google search: http://www.google.com/search?sourceid=navclient&q=log4j%2Eproperties+example. There are many other ways to configure a use log4j, and you might eventually want to change this, but start with a simple file in the WEB-INF/classes directory and log4j will configure itself automatically.
