Print stacktrace into file

Question

I have this error stack trace method which sends to log4j error messages:

public void writeErrorStackMessage(String message)
    {
        log.error(message);
    }

I want also to add printing of stack trace into file.

catch (Exception e)
        {
            lm.writeErrorStackMessage(e.printStackTrace());
        }

The question is what is the proper way to send the error stack as message?

Edit:

public void writeErrorStackMessage(String message)
    {
        log.error(message);
    }


catch (Exception e)
        {
            lm.writeErrorStackMessage(Arrays.toString(e.getStackTrace()));
        }

I modified the code this way.

You can configure log4j.properties to send the stacktrace into file or write to file using PrrintWriter. What do you want? — Masudul, Jun 04 '14 at 08:28

The e.printStackTrace() method also takes an PrintWriter or PrintStream argumument so if your lm object has an OutputStream you should be able to do

e.printStackTrace(new PrintStream (lm.getOutputStream ()));

I modified the code this way. But is there any more elegant solution? – user1285928 Jun 04 '14 at 08:40
what is in-elegant about it? – Scary Wombat Jun 04 '14 at 08:42
Is there a way to do this without Arrays? – user1285928 Jun 04 '14 at 08:45
In that case just use the Exception `getmessage ()` method – Scary Wombat Jun 05 '14 at 00:00
