Solution is to implement an email notification system. The
notification system will generate an email message whenever
the application detects an error. If you are already using
a standard logging framework like log4j.

import java.util.logging.*;
public class JDKLoggingExample
{
private static final Logger log =
Logger.getLogger(JDKLoggingExample.class.getName());
public static void main(String[] args)
{
try
{
log.fine("This is a fine message.");
int i = Integer.parseInt("Hello world");
}
catch (java.lang.Exception ex)
{
log.log(Level.SEVERE, "Caught an exception",
ex);
}
}

---------------------------------------------------------

import org.apache.log4j.*;

public class Log4jExample
{

private static final Logger log =
Logger.getLogger(Log4jExample.class);

public static void main(String[] args)
{
try
{
log.debug("This is a debug message.");
int i = Integer.parseInt("Hello world");
}
catch (java.lang.Exception ex)
{
log.error("Caught an exception", ex);
}
}
}
