log4j:ERROR LogMananger.repositorySelector was null likely due to error in class reloading, using NOPLoggerRepository.
Stopping Tomcat because the context stopped.

log4j.xml:

<appender name="fileAppender" class="org.apache.log4j.RollingFileAppender">
    <param name="MaxFileSize" value="25MB" />
    <param name="MaxBackupIndex" value="10" />
    <param name="File" value="/logs/abc-web.log" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%d [%t] %-5p: %m (%c)%n" />
    </layout>
</appender>

Answer 1

Log4j will create directories while the directory and it's parent directory not exists.

Log4j throws FileNotFoundException while creating directory or file failed without file priviledge.

Check the file priviledge with your app user.

  public
  synchronized
  void setFile(String fileName, boolean append, boolean bufferedIO, int bufferSize)
                                                            throws IOException {
    LogLog.debug("setFile called: "+fileName+", "+append);

    // It does not make sense to have immediate flush and bufferedIO.
    if(bufferedIO) {
      setImmediateFlush(false);
    }

    reset();
    FileOutputStream ostream = null;
    try {
          //
          //   attempt to create file
          //
          ostream = new FileOutputStream(fileName, append);
    } catch(FileNotFoundException ex) {
          //
          //   if parent directory does not exist then
          //      attempt to create it and try to create file
          //      see bug 9150
          //
          String parentName = new File(fileName).getParent();
          if (parentName != null) {
             File parentDir = new File(parentName);
             if(!parentDir.exists() && parentDir.mkdirs()) {
                ostream = new FileOutputStream(fileName, append);
             } else {
                throw ex;
             }
          } else {
             throw ex;
          }
    }

Answer 2

I had this same issue of the FileNotFound exception.

My solution was to remove the appended "/" from the value as so:

<param name="File" value="logs/abc-web.log" />
