I am trying to work with bacnet4j. but unable to find any tutorial or guide. I am using Bacnet-stack simulator for testing. I tried this code to check i am functionality and I have also tried localdevice but both the cases i am getting error of no class definition error in this package com.serotonin.bacnet4j.npdu.Network.

If anybody has any tutorial please provide.
You are missing slf4j dependency. Add slf4j to your class path and it should work.
