Hi Bob, Hi everybody,

I am quite new in Eclipse programming, so perhaps my question will sound a bit odd, but here is my problem:

I currently store the expressions (the code of a script task for example) of my BPMN process in separate files in a project, and not directly in the bpmn file (in the case of a script task, I only have a reference to the real code).

From a builder, when a script file is updated, I would like to retrieve some information from the associated bpmn process and also modify it. I know I can create an EMF resource from the workspace file, but I would like to access the EMF resource currently edited in a BPMN2 editor if one is opened. Is there a way to share the Resource/ResourceSet used by the BPMN2 editor ?

Hi Cédric,

You can adapt the BPMN2 editor to a graphiti Diagram and from that get the Resource that corresponds to a given namespace URI, like this:

Resource getResource (String nsURI) {
	IWorkbenchPage[] pages = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getPages();
	for (IWorkbenchPage page : pages) {
		IEditorReference[] otherEditors = page.findEditors(
		for (IEditorReference ref : otherEditors) {
			IEditorPart part = ref.getEditor(true);
			Diagram diagram = (Diagram) part.getAdapter(Diagram.class);
			if (diagram!=null && diagram.eResource()!=null) {
				ResourceSet rs = diagram.eResource().getResourceSet();
				for (Resource r : rs.getResources()) {
					if (r.getURI().equals(nsURI))
						return r;
	return null;
