check out the Logic example.
In LogicEditor.java, you'll notice this:

ScalableFreeformRootEditPart root = new ScalableFreeformRootEditPart();

List zoomLevels = new ArrayList(3);
zoomLevels.add(ZoomManager.FIT_ALL);
zoomLevels.add(ZoomManager.FIT_WIDTH);
zoomLevels.add(ZoomManager.FIT_HEIGHT);
root.getZoomManager().setZoomLevelContributions(zoomLevels);

IAction zoomIn = new ZoomInAction(root.getZoomManager());
IAction zoomOut = new ZoomOutAction(root.getZoomManager());
getActionRegistry().registerAction(zoomIn);
getActionRegistry().registerAction(zoomOut);
getSite().getKeyBindingService().registerAction(zoomIn);
getSite().getKeyBindingService().registerAction(zoomOut);

viewer.setRootEditPart(root);

This is where the Zoom functionality is initialized.

You will then be able to get the ZoomManager from the Viewer:

ZoomManager manager = (ZoomManager)getGraphicalViewer()
.getProperty(ZoomManager.class.toString());
