External java classes are not invoked from tomcat server

Hi,

I have created a war file where i am calling 2 external java class from bpmn flow.

When I test it in local it working fine (eclipse + camunda) but when i created a war file and place in camunda-bpm-tomcat-7.18.0\server\apache-tomcat-9.0.58\webapps, external java classes are not invoked.

Not sure what I am missing?
