Question

I am getting data from log file and printing it but it was not as formated as in log file my code is,

try

    {
    String strpath="/var/new.log";
    FileReader fr = new FileReader(strpath);
    BufferedReader br = new BufferedReader(fr);

    String ch;
    do {
      ch = br.readLine();

      if (ch != null)
        out.println( ch+"\n");
    } while (ch != null);
    fr.close();
    }

        catch(IOException e){

        out.print(e.getMessage());

        }

Data in my file is this format,

[1324649399] Nagios 3.3.1 starting... (PID=3751)
[1324649399] Local time is Fri Dec 23 09:09:59 EST 2011

My code is printing it in this Format,

How can I get it as it is in the log file?

Answer 1

If I may suggest, this is a better way for structuring the loop that outputs the log:

String strpath = "/var/new.log", ch;
FileReader fr = null;
try {
    fr = new FileReader(strpath);
    BufferedReader br = new BufferedReader(fr);
    while ((ch = br.readLine()) != null)
        out.println(ch);
} catch (IOException e) {
    out.print(e.getMessage());
} finally {
    if (fr != null)
        fr.close();
}

For solving the formatting problems, do as the other answers suggest, and output the log inside a <pre></pre> tag
