I'm trying to switch from using FileAppender to the RollingFileAppender using log4j2 (happens both with beta3 and beta4 jars).
I have it configured as:
<RollingFile name="RollingFile" fileName="${logdir}/${filename}"
filePattern="${logdir}/app-%d{yyyy-MM-dd-hh-mm-ss}_%i.log" >
<PatternLayout>
<pattern>%d %p %C{1.} [%t] %m%n</pattern>
</PatternLayout>
<Policies>
<OnStartupTriggeringPolicy/>
</Policies>
<DefaultRolloverStrategy max="20"/>
</RollingFile>
...
<loggers>
<root level="ERROR">
<appender-ref ref="RollingFile"/>
<appender-ref ref="STDOUT"/>
</root>
...
and in the code, I'm trying to get the logger this way:
Logger logger = LogManager.getLogger(this.getClass());
but I'm getting this exception when I run it:
2013-02-01 17:56:54,773 ERROR Unable to invoke method createAppender in class org.apache.logging.log4j.core.appender.RollingFileAppender for element RollingFile java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.apache.logging.log4j.core.config.BaseConfiguration.createPluginObject(BaseConfiguration.java:723) at org.apache.logging.log4j.core.config.BaseConfiguration.createConfiguration(BaseConfiguration.java:489) at org.apache.logging.log4j.core.config.BaseConfiguration.createConfiguration(BaseConfiguration.java:481) at org.apache.logging.log4j.core.config.BaseConfiguration.doConfigure(BaseConfiguration.java:162) at org.apache.logging.log4j.core.config.BaseConfiguration.start(BaseConfiguration.java:120) at org.apache.logging.log4j.core.LoggerContext.setConfiguration(LoggerContext.java:271) at org.apache.logging.log4j.core.LoggerContext.reconfigure(LoggerContext.java:287) at org.apache.logging.log4j.core.LoggerContext.start(LoggerContext.java:139) at org.apache.logging.log4j.core.impl.Log4jContextFactory.getContext(Log4jContextFactory.java:76) at org.apache.logging.log4j.core.impl.Log4jContextFactory.getContext(Log4jContextFactory.java:31) at org.apache.logging.log4j.LogManager.getLogger(LogManager.java:342) at org.apache.logging.log4j.LogManager.getLogger(LogManager.java:301) ...

It looks as if the config file is being read and the appender is trying to get created but not sure what I'm doing wrong.
I've tried cutting and pasting other people's RollingFileAppender configuration w/o any modification but I still get the above error.
Thanks.
In my case configuration file contain File appender
with RollingFile appender
.
Error was in
fileName
parameter - it have same value in both appenders.
