how to Create a folder for log file using log4j.xml

Question

I just created log4j.xml file like ,

<?xml version="1.0" encoding="UTF-8"?>
<log4j:configuration>
    <appender name="fileAppender" class="org.apache.log4j.RollingFileAppender">
        <param name="Threshold" value="ALL" />
        <param name="MaxFileSize" value="512KB" />
        <param name="MaxBackupIndex" value="10" />
        <param name="File" value="F:/Core_logs/application_log.log" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d{MMM-dd-yyyy HH:mm:ss:SSS} %-5p %m%n"/>
        </layout>
    </appender>

    <!--sets the priority log level for org.springframework -->
    <logger name="org.springframework">
        <level value="info" />
    </logger>
    <!--sets the default priority log level -->
    <root>
        <priority value="all"></priority>
        <appender-ref ref="fileAppender" />
    </root>
</log4j:configuration>

But I have the exception as ,

java.io.FileNotFoundException: F:\Spring_Core_logs\pointel_Aop.log (The system cannot find the path specified)

If I created a folder Core_logs manually in the particular location means, it works fine and log file created.

How to create the folder , if the folder is not exist in a particular location?

[Configuring Java FileHandler Logging to create directories if they do not exist](http://stackoverflow.com/questions/1263876/configuring-java-filehandler-logging-to-create-directories-if-they-do-not-exist) might help. Which version of log4j are you using? It looks like `1.2.15+` should already support it. — andyb, Dec 11 '13 at 14:22

EDIT:

This here could also help you/looks like the best solution for you: Configuring Java FileHandler Logging to create directories if they do not exist

It seems like log4j version 1.2.15 does it. Look for an answer below from Arun P Johny, he posted a piece of code from the log4j sourcecode. I overlooked it because it was not accepted as an answer.
