    copied!<p>Not sure what you really wanna do....</p> <p>if your log4j.xml is in the classpath, when you start your app-server, it should be loaded automatically.</p> <p>Check the console when you start your server and you should see your log4j info.</p> <p>You can also put debug=true:</p> <pre><code>&lt;log4j:configuration debug="true" xmlns:log4j="http://jakarta.apache.org/log4j/"&gt; </code></pre> <p>in your xml. you will be able to see a lot of info about your config.</p> <p>Now if you want to access the appenders you configured in the log4j.xml, all you have to do is:</p> <pre><code>Logger mylogger = Logger.getLogger("MyAppenderName"); </code></pre> <p>Ok, i think you wanna load a custom log4j config file! In a web app context, you will need 2 things:</p> <p>create a contextListnerServlet; modify your web.xml</p> <p>ServletListner:</p> <pre><code>public class StartupListener implements ServletContextListener { @Override public void contextDestroyed(ServletContextEvent arg0) { // Cleanup code goes here } @Override public void contextInitialized(ServletContextEvent sce) { Logger logger = null; String log4jFile = sce.getServletContext().getInitParameter("log4jFileName"); DOMConfigurator.configure(sce.getServletContext().getRealPath(log4jFile)); logger = LogManager.getLogger(StartupListener.class.getName()); logger.debug("Loaded: " + log4jFile); } </code></pre> <p>web.xml:</p> <pre><code>&lt;context-param&gt; &lt;param-name&gt;log4jFileName&lt;/param-name&gt; &lt;param-value&gt; WEB-INF/config/log4j-my.xml &lt;/param-value&gt; &lt;/context-param&gt; &lt;listener&gt; &lt;listener-class&gt; com.yourpackage.StartupListener &lt;/listener-class&gt; &lt;/listener&gt; </code></pre> <p>Hope it helps</p>
