Topic: NullPointerException from JPPFExecutorService example on Future.get() (Read 4398 times)

Dear all,

I cannot get the JPPFExecutorService example on p49 of the JPPF-User-Guide to work. It did have compile problems which I fixed in the attachment. I have a server and node running on a remote machine. The standard TemplateApplicationRunner example DOES work.

The exception comes when Future.get() is called from a submitted task.

Assistance appreciated, thanks!

~Mark.

Hello Mark,

I can indeed rerpoduce the same problem. I registered a JPPF bug for it: 3486440 - JPPFExecutorService.throws NPE on Future.get()
I also published a patch for it, which you can ghet from there.

Can you give it a try and let us know of the outcome?

Sincerely,
-Laurent

Hi Laurent,

That does appear to fix it. The code runs as expected, thank you! I am also experiencing another problem which I believe to be Eclipse based. I will post that in another topic.

Thank you,
~Mark.
