Reporting it as an error is overstating the significance of a validation failure. log4j:ERROR The content of element type appender must match (errorHandler?,param*,layout?,filter*,appender-ref*) The log4j.dtd specifies that elements in a configuration file appear in a specified order. log4j's DOMConfiguration isn't as picky.

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

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. - To unsubscribe, e-mail: log4j-user-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-user-h...@logging.apache.org
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{-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.

Re: Extra RollingFileAppender 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.
