Hi,
I was testing a custom job handler (trigger an event when dueDate expires) but now I undeployed it.
Now I cannot get the engine started due to an exception saying he cannot find the job handler.
It is my personal development server so no harm done but I was wondering;
Is there a clean way to remove such a job handler from the engine?
Kind regards
