I am using Spring schedule. I configured the following Cron expression to run my task every Tuesday night at 9pm, 

"0 0 21 * * TUE"

However, I am getting the following exception when am starting the application

Encountered invalid @Scheduled method 'runSchduler': Cron expression must consist of 6 fields

Is my Spring Cron expression wrong?

Is my Spring Cron expression configured, to run every Tuesday night at 9 wrong?

Yes :)

But try, 

0 0 21 ? * TUE

Or with the Spring annotation:

@Scheduled(cron = "0 0 21 * * TUE")

The following is a really handy website for creating Cron expressions.

http://www.cronmaker.com/ Take note: Just remove the last element from the created expression to use it with Spring scheduling.

And a nice way to verify it in Natural Language here

Looks like you have a field too much?

Just generated this based on your criteria of Tuesdays at 9PM "0 21 * * 2"
