[jboss-user] [Installation, Configuration & DEPLOYMENT] - Re: JBOSS log rotation

[ran_sushmi]

hi,
  | 
  | thanks, for your answer. This was helpful, but there is this code in our JBOSS application 'log4j.xml' file which is difficult to understand. I am pasting the initial contents of the file off which I am not able to make out much. The contents are:-

  | 
  | Can, the lines of the code be explained. By the way, is there any way to upload a file on the 
  | forum.
  | 
  | I hope, my question is clear.
  | 
  | Please, help in solving the doubt.
regards
