The initial log4j2.xml file was

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="INFO" monitorInterval="60">
    <Properties>
        <Property name="LOG_HOME">./logs</Property>
    </Properties>

    <Appenders>
        <RollingFile
            name="RollingFileAppender"
            fileName="${LOG_HOME}/log.log"
            filePattern="${LOG_HOME}/log.log.%d{yyyy-MM-dd}.%i">
            <ThresholdFilter level="INFO" onMatch="ACCEPT" onMismatch="DENY"/>
            <PatternLayout pattern="%d{DEFAULT} %p %t %c %L: %m%n"/>
            <Policies>
                <OnStartupTriggeringPolicy/>
                <!--<TimeBasedTriggeringPolicy/>-->
                <SizeBasedTriggeringPolicy size="256MB"/>
            </Policies>
            <DefaultRolloverStrategy max="8"/>
        </RollingFile>
    </Appenders>

    <Loggers>
        <Root level="INFO">
            <AppenderRef ref="RollingFileAppender"/>
        </Root>
    </Loggers>
</Configuration>

And then I changed filePattern to

filePattern="${LOG_HOME}/log.log.%i"

Log file names still contain date.

   2013-12-15 15:26:53,085 ERROR Null object returned for RollingRandomAccessFile i
   n Appenders

2. Try a different build, i can’t think of anything else.

3. Nope, I tried about 5 1.7 most recent bilds and the recconended build for 1.6.4 and they all show the same error spamming my console.

4. Username does not have access to the location you are running your server in:

   2013-12-15 15:26:53,031 ERROR Cannot access RandomAccessFile {}) java.io.FileNot
   FoundException: logslatest.log (Access is denied)

5. How can I give my username access?

7. Better idea: Copy your server to your Documents

8. Well i have the same problem but i get a random file named ‘Logs’. I have the same problem when i want to run an ‘.exe’ normal minecraft server. I hope you can help us.

9. Thank you so much, it worked!
