Hi ABCDEFG,

You should be able to use java libraries to read line by line. Something like this:

  FileInputStream fstream = new FileInputStream("textfile.txt");
  DataInputStream in = new DataInputStream(fstream);
  BufferedReader br = new BufferedReader(new InputStreamReader(in));
  def strLine;
  
  while ((strLine = br.readLine()) != null)   
  {
   log.info "$strLine";
  }
  
  in.close();


Let me know if this works.
