Extra RollingFileAppender with NLOG4j
I'm trying to get the RollingFileAppender from the extra log4j companion file working but I'm having problems configuring the appender. I am using this with the most current version of NLOG4J
The following is my config file:
<?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>
<appender name="logFileAppender" class="org.apache.log4j.rolling.RollingFileAppender">
<rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
<param name="FileNamePattern" value="/log/metrics.%d{yyyy-MM-dd-HH}.log" />
</rollingPolicy>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%m%n" />
</layout>
</appender>
<!-- -->
<!-- Loggers -->
<!-- -->
<logger name="com.barcap.eq.common.metric.LoggingMetric" additivity="false">
<level value="INFO" />
<appender-ref ref="console" />
<appender-ref ref="logFileAppender" />
</logger>
<root>
<priority value ="debug" />
<appender-ref ref="console" />
</root>
</log4j:configuration>
At startup, I get the following errors:
log4j:ERROR Element type "rollingPolicy" must be declared.
log4j:ERROR The content of element type "appender" must match "(errorHandler?,param*,layout?,filter*,appender-ref*)".
If I attempt to write to the appender, I then get:
log4j:WARN Please set a rolling policy for the RollingFileAppender named 'logFileAppender'
log4j:ERROR No output stream or file set for the appender named [logFileAppender].
I think the issue is that the rollingPolicy element isn't defined in log4j.dtd but I'm not sure how to proceed with this. Is NLOG4J not compatible with the companion jar?
Thanks.

This also occurs with earlier versions of Apache log4j and is due to the lack of a definition of rollingPolicy in the log4j.dtd. The lack of a definition in the log4j.dtd results in a failed XML validation, but noting more. Reporting it as an error is overstating the significance of a validation failure.

The log4j.dtd specifies that elements in a configuration file appear in a specified order. log4j's DOMConfiguration isn't as picky. This warning can be eliminated by ordering the contents of an appender element as shown in the warning.

This could be due either to a bad configuration file or some mismatch between NLOJ4J and the appender.

That results in an misleading warning, but would not result in a failure to configure.

As mentioned, NLOG4J is a fork of Apache log4j and is not supported here. If the configuration file works with Apache log4j, then you could try configuring with the org.apache.log4j.extras.DOMConfigurator which may or may not work with NLOG4J.

NLog4j is not an Apache Logging project. It's a fork of Log4j hosted outside
of Apache Logging. Please try with an official Log4j version and respond back
if you run into issues.
