Handling exception logging in a Java task scheduler program?

Question

I need to design a Task Scheduler Where
1) User should be able to schedule multiple task at the same time.
2) There should be proper error handling on failure of any task and should not affect the other running tasks.
I found the related programme at http://www.roseindia.net/java/example/java/util/CertainAndRepeatTime.shtml
My concern is about handling of point 2 in program provided at above link. Say I schedule a recurring mail send process in above program which will be run first time on 12 september 2011 at 2 am, and will be repeated after every 2 hours Say a one process fais at 8 am. I want to log it in log file with task name and time details. Now if I look at above programme i.e CertainAndRepeatTime.java. This program will exit once it schedules all the tasks. Where and how should handle the logging?
Posted at http://stackoverflow.com/questions/7377204/handling-exception-logging-in-a-java-task-scheduler-program but folks suggesting Quartz scheduler . My Limitation is that i can't for quartz because my project allows me to use only standard java library. Is there any way we can handle logging in the same programme in case of exception.

Answer 1

Well, first of all I wouldn't trust any code from roseindia. So you might want to look for more reliable advice.
As for your logging, you can add it for example to the TimerTask itself. I don't recommend adding logging to that roseindia cr*p though.
