server.socket_port      = 10005
server.thread_pool      = 256
socket.queue_size       = 10 ; some comments
server.environment      = production        ; some comments
tools.encode.on         = True ; some comments
tools.decode.on         = True
;tools.gzip.on           = True ; some comments and commented parameter
;log.screen              = False ; some comments and commented parameter
[mail]
serveraddress = 172.16.9.8

Java: convert array of integers to Integer Array List an viceversa

//  convert array of integers to Integer Array List
public ArrayList<Integer> convertToIntegersArrayList(int[] mensaje)
    {
        ArrayList<Integer> returnArray = new ArrayList<Integer>();      
        for (int i=0; i < mensaje.length; i++)
        {
            returnArray.add((Integer)mensaje[i]);
        }
        return returnArray;
    }

//  convert  Integer Array List  to array of integers
public int[] convertToArrayOfIntegers(ArrayList<Integer> integers)
    {
        int[] ret = new int[integers.size()];
        for (int i=0; i < ret.length; i++)
        {
            ret[i] = integers.get(i).intValue();
        }
        return ret;
    }

Java: comparing chars

String messageText = "test";
char lastChar = messageText.charAt(messageText.length()-1);
if(lastChar!='e' && lastChar!='s' ){
      System.out.print("the last char is different of e and s , it's : "); // the last char is different of e and s , it's :
      System.out.println(lastChar); // t
}
