Can't get a RollingFile working with log4j2 - spring

Question

I'm trying to configure log4j2 to write a rolling log file to disk, but I can't get it to work. No log file appears at the given path and the Glassfish server.log doesn't show any Spring logging at all. I've read a lot of similar questions on SO, but none of the proposed solutions have worked in this case. Can anyone help me? I'm using Spring 3.0 on a Glassfish 3.1 application server.
From my pom.xml:
<properties>
<junit.version>4.11</junit.version>
<tiles.version>3.0.3</tiles.version>
<slf4j.version>1.7.5</slf4j.version>
<log4j.version>2.0-beta9</log4j.version>
</properties>
<dependencies>
<dependency>
<artifactId>jcl-over-slf4j</artifactId>
<groupId>org.slf4j</groupId>
<version>${slf4j.version}</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>${log4j.version}</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-slf4j-impl</artifactId>
<version>${log4j.version}</version>
</dependency>
</dependencies>
And here's my log4j.xml:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="INFO">
<Properties>
<Property name="fileName" value="C:/temp/rolling-file.log"/>
<Property name="fileNamePattern" value="C:/temp/rolling-file-$d{dd-MM-yyyy}-%i.log"/>
<Property name="logPattern" value="%d{dd-MM-yyyy HH:mm:ss,SSS} [%t] %-5p %c - %m%n"/>
</Properties>
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="${logPattern}"/>
</Console>
<RollingFile name="RollingFile" fileName="${fileName}" filePattern="${fileNamePattern}">
<PatternLayout pattern="${logPattern}"/>
<Policies>
<TimeBasedTriggeringPolicy/>
<SizeBasedTriggeringPolicy size="20MB"/>
</Policies>
<DefaultRolloverStrategy max="10"/>
</RollingFile>
</Appenders>
<Loggers>
<Logger name="my.root.package" level="info" additivity="false">
<AppenderRef ref="Console"/>
<AppenderRef ref="RollingFile"/>
</Logger>
<Root level="info">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
</Configuration>

Besides the excellent point made by M. Deinum, it turns out my log4j2.xml needed to be changed to the following:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="DEBUG">
<Properties>
<Property name="fileName">C:/temp/rolling-file.log</Property>
<Property name="fileNamePattern">C:/temp/rolling-file-%d{dd-MM-yyyy}-%i.log</Property>
<Property name="logPattern">%d{dd-MM-yyyy HH:mm:ss,SSS} [%t] %-5p %c - %m%n</Property>
</Properties>
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="${logPattern}"/>
</Console>
<RollingFile name="MyRollingFile" fileName="${fileName}" filePattern="${fileNamePattern}">
<PatternLayout pattern="${logPattern}"/>
<Policies>
<TimeBasedTriggeringPolicy/>
<SizeBasedTriggeringPolicy size="20MB"/>
</Policies>
<DefaultRolloverStrategy max="10"/>
</RollingFile>
</Appenders>
<Loggers>
<Logger name="my.root.package" level="info" additivity="false">
<AppenderRef ref="Console"/>
<AppenderRef ref="MyRollingFile"/>
</Logger>
<Root level="info">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
</Configuration>
Performed changes:
The value attributes of the Property elements were not parsed correctly. Specifying them as body of the Property element seems to solve this.
There was a mistake in the value of the fileNamePattern property. I used $d to denote the date, but it should be %d.
Apparently log4j2 doesn't like a RollingFile element with the name "RollingFile". After I changed it, logging started working.

You might need to include log4j-api to the pom dependencies (http://logging.apache.org/log4j/2.x/faq.html#which_jars ).
About the properties: if the problem goes away by putting the values in the config directly:
<RollingFile name="RollingFile" fileName="C:/temp/rolling-file.log"
filePattern="C:/temp/rolling-file-$d{dd-MM-yyyy}-%i.log">
<PatternLayout pattern="%d{dd-MM-yyyy HH:mm:ss,SSS} [%t] %-5p %c - %m%n"/>
then you may have found a bug. In that case, could your raise this issue in the log4j2 Jira issue tracker?
