a logger and a printStackTrace in Java

Hello:

I have a simple class logger, for applications and keep a log of exceptions:

Code:

import java.io.*;





/** Class that will act as a general logger for the system, intended for debugging and status control

  *

  * @author KingCrimson

  */

public final class Logger

{



                private static PrintWriter file;



                public static synchronized void log(String what)

                {

                        try



                        {

                                file = new PrintWriter(new FileWriter("c:/ccss.log", true));

                                file.println(what);

                                file.close();

                        }

                        catch(Exception e)

                        {

                                System.out.println("Error en archivo");

                                e.printStackTrace();

                        }

                }// log



}// logger

and I wanna print there all info related to exceptions, but in a catch statement, the Exception e has a method e.printStackTrace() wich is void, can I take that info and pass it as a string so it suits my Logger class and do something like:

Logger.log(e.printStackTrace());

I've been using the e.getMessage() and the e.toString() but it's not quite the same

Please Help! Thanks a lot

I'm not sure if it works, but if you do a

StackTraceElements[] array = exception.getStackTrace();

And then you cycle through each element of the array, executing the following instruction in each cycle:

Logger.log(array[i].toString());

I think that should do the job right?

Hola paisano!!

It did work, thanks a lot! now I just have to struggle with this sql thing.... any idea what SQLState keycode: S1000 stands for?
I'm using mySql and org.gjt.mm.mysql.Driver as a driver for Java

Thanks a lot!
