The Event class is located in the same package as the process itself, and the process contains Script with following content:

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import Event;


Event event = new Event();
event.setDate_time(java.time.LocalDateTime.now().format(java.time.format.DateTimeFormatter.ofPattern("dd-MM-yyyy HH:mm:ss")));
event.setEvent_code("TESTCODE");
event.setProduct_service_code("TEST_CODE");
event.setSource("TEST_SOURCE");
event.setTracking_number("XXX");
event.setBranch("TEST_BRANCH");
event.setUser_id("TEST_USER");


kcontext.setVariable("pEvent", event);

System.out.println("event ----->"+event);
