title: can't able to implement log4j for JBOSS EAP 7 using java?
body: <p>i have an application, i have applied log4j, but i can't able to create log file inside jboss application.
  when i put absolute path of system in <code>log4j.appender.file.File= D:/log/application.log</code> it was working fine but when i put  <code>log4j.appender.file.File= ${jboss.server.home.dir}/log/application.log</code> it is not working.</p>
  
  <pre><code># Root logger option
  log4j.rootLogger=DEBUG, stdout, file
  
  # Redirect log messages to console
  
  log4j.appender.stdout=org.apache.log4j.ConsoleAppender
  log4j.appender.stdout.Target=System.out
  log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
  log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
  
  # Redirect log messages to a log file, support file rolling.
  log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
  #log4j.appender.file=org.apache.log4j.RollingFileAppender
  
  log4j.appender.file.File= ${jboss.server.home.dir}/log/application.log
  log4j.appender.file.MaxFileSize=5KB
  log4j.appender.file.MaxBackupIndex=10
