1.3 | 3 | XWiki uses Commons Logging for logging. By default XWiki is configured so that Commons Logging uses log4J. XWiki's Log4J configuration is located inside XWiki's JAR (xwiki.jar), in a <tt>[log4j.properties>http://fisheye2.cenqua.com/browse/~raw,r=trunk/xwiki/xwiki-platform/core/trunk/src/main/resources/log4j.properties]</tt> file. XWiki' JAR is itself located in your <tt>WEB-INF/lib/</tt> directory. |

1.4 | 5 | #info("By default XWiki is configured to log everythinf both on the console and in a xwiki.log file located in the directory from where you have started the JVL. This is usually the directory from where you have started your application server/Servlet container. It's recommended to either start the JVM from a location where it's ok to output the xwiki.log file or to create a custom Log4J configuration as explained below.") |
