Finally got it working..... a bit. However, I am not using any processes. Just creating task and setting all those deadline things. The emails are being sent out as notifications but I get a NullPointerException like this.
java.lang.NullPointerException

I believe this is because I am not setting any WorkItemManager, which I dont have because I dont have any process.
Is my understanding correct.
