[jira] [Updated] (MINIFI-548)
[ https://issues.apache.org/jira/browse/MINIFI-548?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Florin Gheciu updated MINIFI-548:
---------------------------------
Description:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %c\{1} - %m%n"/>
</layout>
</appender>
<root>
<priority value ="debug" />
<appender-ref ref="console" />
</root>
</log4j:configuration>
h3. XML Configuration Format
In order to better understand the more detailed examples, it is useful to understand the expected format for the xml configuration files. This is defined by the log4j.dtd which is located in the log4j distribution jar in the package org.apache.log4j.xml. The contents of this file will not be listed in its entirety, so please feel free to open/print the file yourself. If you are not familiar with xml dtd file formats, then you should go find a good book on that subject first.
Near the beginning of the file is the following declaration:
{noformat}
<!ELEMENT log4j:configuration (renderer*, appender*,(category|logger)*,root?, categoryFactory?)>
{noformat}
This element defines the expected structure of the xml configuration file: 0 or more renderer elements, followed by referat 0 or more appender elements, followed by 0 or more logger elements, followed by 0 or 1 root element, followed by 0 or 1 categoryFactory element. If this order is not followed, then errors will be printed by the xml parser at the time the xml file is read in. Also, as a note, the "category" element is the same as the logger element. Prior to log4j version 1.2, loggers were known as category. Much of the documentation still refers to category. Just understand that they are the same thing.
