DOMConfigurator supports rudimentary variable interpolation. Variables found
in the System properties can be used in the XML config file like this:
<appender name="FOO" class="org.apache.log4j.DailyRollingFileAppender">
<param name="file" value="${log.home}/foo.log" />
<param name="append" value="true" />
<param name="datePattern" value="'.'yyyy-MM-dd" />
<param name="threshold" value="DEBUG" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="${log4j.appender.FOO.pattern}"
/>
</layout>
</appender>
Hope this helps.

| file
|
|
|
| I am using the DOMConfigurator, and would like to make use of the variable
| substitution available to Log4J.
|
| Does anyone have an XML example of this?
|
| The book only has a log4j.properties file example, and I do not know the
| XML syntax. I get SAXParser errors...
