<div class="jive-rendered-content"><p>I am trying out a sample process with a human task. Configured persistence for both Task server and process instnace in postgresql. Process flow is stopping at the human task as expected. After this I am completing the task using a human task client. Problem is that after this the process is not proceeding to complete. I am using JPAKnowledgeService and CommandBasedWSHumanTaskHandler. Is there anything additional need to be done for completing the process another than invoking the task api at task server ? </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Is there any significance to the task name & name we give to the Human Task in the process ?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Code used for starting process.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>        </p><pre class="jive-pre"><code class="jive-code jive-java">        Logger logger = Logger.getLogger(this.getClass().getName());
