For Example I have 1 modler like this. I have implement Service Task using Java Class and in this class I want to use RuntimeService.Signal() as an trigger to continue my process.

I have try this code:

Execution execution1 = runtimeService.createExecutionQuery().processInstanceId(execution.getProcessInstanceId()).activityId(“MyIdOfReceiveTask”).singleResult();
