Huh ?



What if all I had to do was...




ShoppingList list = new ShoppingList();list.addItem(“bread”);list.addCollaborator(“[email protected]”);





OswService service = OswService.getInstance();service.login(“[email protected]”, “******”);service.post(list);





OswService service = OswService.getInstance();service.login(“[email protected]”, “******”);service.post(list);

service.registerInboxEventHandler(new InboxEventHandler() { public void handleEvent(InboxEvent event) { if (event.getObjectType().equals(“http://acme.com/shoppinglist“)) {

notify(); } }});

http://acme.com/shoppinglist
