jobService

I am currently working submitting a custom cron job in Bonita. I actually managed to create a job and submit it. I can see the Job details in the Bonita Engine Database. But it fails when it is going to trigger. Anyone who came across the same situation or anyone knows what is the error? Please see my code below.

Following is the exception I am getting.

After installing the subscription edition, the server does not start.
This is the error message in the log:
