Getting error

The process could not be started. : Cannot instantiate process definition SimpleDemo:1:d9b7b90a-f1b9-11e8-a66c-34689537f273: 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

How exactly have you deployed the process?

  1. copy war file to the camunda-bpm-tomcat-7.9.0\server\apache-tomcat-9.0.5\webapps
  2. Run start-camunda.bat
    Then my application is showing in the Dashboard » Processes

So there are 2 possibilities:

  • You’re deploying the process without the class you’ve described in the service task
  • The Service task you’re trying to call has a different qualified name

Thanks for quick reply error was not there now, it was due to unchecked on Executable properties panel. When I start the process SimpleDemo it was showing “The process has been started.”
but in the process definition deployed “Running Instances” is 0 for “SimpleDemo”
