Unable to Start SimpleDemo Process from task list

Hi All,

I’m new to Camunda and started using 30 days free trial of Enterprise Edition. I have followed Niall tutorial video 2 and created a project “SimpleDemo”. I have completed .war file creation but couldn’t find the path in my Camunda folder to deploy it. Then I have deployed the process.bpmn directly from cockpit and tried to start the process from tasklist. While trying to start the process, I encountered below error

The process could not be started. : Cannot instantiate process definition SimpleDemo:1:19013576-d400-11eb-9dc1-9457a5b2b44d: ENGINE-09008 Exception while instantiating class ‘com.camunda.demo.SimpleDemo.CheckWeatherDelegate’: ENGINE-09017 Cannot load class ‘com.camunda.demo.SimpleDemo.CheckWeatherDelegate’: com.camunda.demo.SimpleDemo.CheckWeatherDelegate

Could you please advise me to resolve this error.

Note : Under the Camunda folder I’m able to see below folders along with start.bat file

camunda-h2-default
configuration
