Question about command in TaskScheduler example #23

Open HurSungYun opened 9 years ago

HurSungYun commented 9 years ago

We have a submit Task command in TaskScheduler

/submit?cmd=COMMAND: submits a Task to execute COMMAND, and returns the Task id.

However, I cannot find what COMMAND can execute a Task.

Would you tell me what line can be a example for COMMAND?

I tried PrimTask for command, but it trigger IOException.

Take a look at TaskScheduler. You should be able to figure it out by looking at the code.

I figured out of my misunderstanding for TaskScheduler code. Sorry for premature questioning
