Clients can optionally pass in a java.util.logging.Logger to where the client logs messages. If there is no logger specified, the workflow service client code does not log anything. The code sample below shows how to pass a logger to the workflow service clients:

java.util.logging.Logger logger = ....;

IWorkflowServiceClient client =
WorkflowServiceClientFactory.getWorkflowServiceClient(WorkflowServiceClientFactory
.REMOTE_CLIENT, properties, logger);
