Hi Guys,

We have requirement where we need to load internal and external java delegate classes from a jar, so that process engine can read those same during execution
But I am unable to achieve that.Throwing below exception

[ERROR] [2019/11/13 15:19:35.035] [pool-1-thread-3] [o.c.b.e.context] - ENGINE-16004 Exception while closing command context: ENGINE-09008 Exception while instantiating class 'com.reactore.hf.asset.tasks.ServiceTaskTest': ENGINE-09017 Cannot load class 'com.reactore.hf.asset.tasks.ServiceTaskTest': com.reactore.hf.asset.tasks.ServiceTaskTest
org.camunda.bpm.engine.ProcessEngineException: ENGINE-09008 Exception while instantiating class 'com.reactore.hf.asset.tasks.ServiceTaskTest': ENGINE-09017 Cannot load class 'com.reactore.hf.asset.tasks.ServiceTaskTest': com.reactore.hf.asset.tasks.ServiceTaskTest
	at org.camunda.bpm.engine.impl.util.EngineUtilLogger.exceptionWhileInstantiatingClass(EngineUtilLogger.java:82)

Any suggestions on this?

External java delegates are in classpath? What is the deployment strategy(jar/ear/war) you are following?

camunda process application deployment strategy? Microservice or Tomcat/Wildfly distribution?
