it is read from the processdefinition xml file itself.
Which task is active is based on the name.

But the information is exposed nowhere via an API? Can I get a copy of the
process definition xml via the API?

Hello Ronald,
thank you for your answer. Could you point me to the file where the reading of
the co-ordinates to show the current process diagram is done?
Thanks,
Sebastian

Okay, I overlooked getActivityCoordinates() in RepositoryService. But how to
retrieve the process image from the engine?

Reply to the post :
getResourceAsStream (like you normally would loading an image from a classpath
;-)) om the RepositoryService.
You just have to know the name of the image as it was deployed in the process
archive.

| repositoryService.getResourceAsStream(deploymentId, resourceName)

And I have to know the deploymentId. Is there a way to determine to which
deployment a process belongs?

Have a look at the sourcecode of the console or the jbpm testcase on how this
is done (have no time to do that myself)
things like 'grep -R getResourceAsStream |grep -v target |grep -v svn' work
amazingly well if you do not have an ide at hand)

Thanks for the hint Ronald, I managed to succeed without looking how the
console deals with it. They only thing missing was getting the image from the
deployment in a comfortable and general way. So your hint helps a lot. I am now
doing the image manipulation myself.

I succeded without looking deeper into the console code. Then I pushed submit

What the 3 console does (and I in my JSF console) is draw the rectangles in
DHTML, so the image stays the same. Nice thing about that is that you can also
display other details of a node on e.g. mouse-over etc.
I'm not sure how the GWT console for 4 does this btw, might be like you do it
or
I noticed this because the console retrieves the image via the REST-interface
and there is just the possibility to get the original image. I think both
methods have advantages and disadvantages.

I feel a bit lost in the source code of the console but I had already managed
to find the section for showing the diagram and there was a method call
similiar to:
| info = getActiveTaskNodeInfo();
| x = info.getX();
| y = info.getY();
|
So the co-ordinates of the task nodes placed in
13 matches
