Log4j is not able to write the files to jetty logs directory

[Sumukh Deshpande]

I have an application running on Jetty 8.0.

I have configured the log4j to write the logs to a file. Here is the configuration.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">

    <appender name="consoleAppender" class="org.apache.log4j.ConsoleAppender">
        <param name="Threshold" value="DEBUG" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d%-5p  [%c{1}] %m %n" />
        </layout>
    </appender>

    <appender name="fileAppender" class="org.apache.log4j.RollingFileAppender">
        <param name="Threshold" value="INFO" />
        <param name="File" value="someLogFileName.log" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d%-5p  [%c{1}] %m %n" />
        </layout>
    </appender>

    <logger name="com.somename">
        <level value="debug" />
        <appender-ref ref="consoleAppender" />
        <appender-ref ref="fileAppender" />
    </logger>

</log4j:configuration>

I have even set the permission for the user which is running the Jetty instance.

The log directory of the Jetty has following permissions:

drwxrwsr-x  2 someuser somegroupuser   4096 Feb 18 05:27 logs

But still getting exception.

Can someone guide me on what could be done to solve this problem?

You forgot to specify the full path to the log file. So the result is that log4j tries to write to Jetty's current working directory, rather than to its log directory. Which it doesn't have the authority to do, but that doesn't matter because it isn't what you want anyway.

Paul,
I tried specifying the path as {$jetty.home}.

But it instead created a directory by that name in the installation folder of Jetty .

What path should be specified when running the app on Jetty ?
