<div class="jive-rendered-content"><p>To get the status of a process graphically, you need to find out the coordinates of the activity which is currently pending. The coordinates are saved in the bpmn file and can be retrieved as following :</p><pre class="jive-pre"><code class="jive-code jive-java">process = kbase.getProcess(processDefId);
ArrayList<Object> coordinates = <font color="navy"><b>new</b></font> ArrayList<Object>();
<font color="navy"><b>try</b></font>
