------------------------------------
Summary: InvocationTargetException with RollingFileAppender in
Log4J2
Key: LOG4J2-706
URL: https://issues.apache.org/jira/browse/LOG4J2-706
Project: Log4j 2
Issue Type: Question
Components: Appenders
Affects Versions: 2.0-rc2
Reporter: David Roberts
Priority: Minor
I'm trying to use a RollingFileAppender in Log4J2 and apparently I'm missing
something. The file is created with 0 bytes, but no logging goes to it. When
I turn on the trace I see the following error message logged (to the console)
by log4J2:
2014-07-08 19:51:11,354 DEBUG Starting RollingFileManager c:/logs/blah.log

This is my config file:
<?xml version="1.0" encoding="UTF-8"?>
<configuration status="TRACE" verbose="false">
<appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} -
%msg%n"/>
</Console>
<RollingFile name="Blah" fileName="c:/logs/blah.log"
filePattern="c:/logs/blah-%i.log">
<PatternLayout pattern="%d %p %c: %m%n"/>
<Policies>
<TimeBasedTriggeringPolicy />
<SizeBasedTriggeringPolicy size="1 MB"/>
</Policies>
<DefaultRolloverStrategy max="10"/>
</RollingFile>
</appenders>
<loggers>
<root level="INFO">
<appender-ref ref="Blah" level="INFO"/>
</root>
</loggers>
</configuration>
It's probably something basic but I can't find it. I posted on stackoverflow
and Remko Popma asked me to post a ticket here.
I was getting the problem on rc1, but I have now updated to rc2 and I still see
the same issue.
