+/**
+ * Log4j-based implementation for logging. This logger should be used
+ * by loaders that have prefer <a target=_new href="http://logging.apache.org/log4j/docs/">log4j</a>-based logging.
+ * <p>
+ * Here is a typical example of configuring log4j logger in GridGain configuration file:
+ * <pre name="code" class="xml">
+ *      &lt;property name="gridLogger"&gt;
+ *          &lt;bean class="org.gridgain.grid.logger.log4j.GridLog4jLogger"&gt;
+ *              &lt;constructor-arg type="java.lang.String" value="config/gridgain-log4j.xml"/&gt;
+ *          &lt;/bean>
+ *      &lt;/property&gt;
+ * </pre>
+ * and from your code:
+ * <pre name="code" class="java">
+ *      GridConfiguration cfg = new GridConfiguration();
+ *      ...
+ *      URL xml = U.resolveGridGainUrl("config/custom-log4j.xml");
+ *      GridLogger log = new GridLog4jLogger(xml);
+ *      ...
+ *      cfg.setGridLogger(log);
+ * </pre>
+ *
+ * Please take a look at <a target=_new href="http://logging.apache.org/log4j/1.2/index.html">Apache Log4j 1.2</a>
+ * for additional information.
+ * <p>
+ * It's recommended to use GridGain logger injection instead of using/instantiating
+ * logger in your task/job code. See {@link org.apache.ignite.resources.IgniteLoggerResource} annotation about logger
+ * injection.
