Internal server error while creating Task Listener

Hi Team,
I was trying to create a Task create Listener to execute some custom logic.
I have created a java class DynamicAssignment inside the package com.example.flowable

I am getting the error:
“Internal server error”,“exception”:“couldn’t instantiate class com.example.flowable.listeners.DynamicAssignment”

I hope I have mapped the listener class correctly in the process definition, not sure why this is not working. Could you please help. Thanks in advance

Is the class in the classpath?


*I would like to join the source code development Do you have flowable source learning materials,

@martin.grofcik Thank you for the response

The issue got fixed when I gave the qualified name of the java class.
