Our customer a major financial giant wants a "Where Is the Process Now" feature
as is available in some of the BPM products. I have looked at the
GraphViewerPluginImpl.java and ProcessActivityPluginImpl.java of jbpm-gwt-graph project
and got some idea on how to get the diagram of a process on the fly and also overlay a red
arrow .jpg file on the active node to signify the current state of the process
pictorially. I followed this
http://www.simplethoughtsonline.com/2012/09/displaying-jbpm-diagram-of-cu...
However, I also looked at the simulation video here
http://kverlaen.blogspot.be/2012/11/jbpm-54-released.html
(http://kverlaen.blogspot.be/2012/11/jbpm-54-released.html) The way the path is tracked in
the simulation is actually nice and we want to implement soething like that by showing the
process and highlighting the path the process has taken till now.
Any thoughts on how could it be done elegantly?
With regards
Anindya

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 :
process = kbase.getProcess(processDefId);
ArrayList<Object> coordinates = new ArrayList<Object>();
try
{
List<NodeInstanceLog> nodeInstanceLogList;
for (Node node : (Node[])((WorkflowProcessImpl) process).getNodes())
{
nodeInstanceLogList =
JPAProcessInstanceDbLog.findNodeInstances(Long.parseLong(processInstanceId), new
Long(node.getId()).toString());
if(nodeInstanceLogList.size() == 1)
{
logger.info("Name of the Node : "+node.getName());
coordinates.add(node.getMetaData().get("x"));
coordinates.add(node.getMetaData().get("y"));
coordinates.add(node.getMetaData().get("height"));
coordinates.add(node.getMetaData().get("width"));
}
}
coordinates.add(processName);
}
catch(Exception e)
{
CustomExceptionHandler.handleException(e);
}
Once you have the coordinates you can use div tags in html to relatively places images of
process and arrow.

Yes, I am aware of that and I have posted the links of that too. However, that is not what
I am looking for. The way the path is tracked in the new jBPM Process Simulation is
actually nice and we want to implement something like that by showing the process diagram
and highlighting the entire path the process has taken till now.
