Was just about to say that looks fine too, when I saw the problem :) The fact that you put your Person object in the cache doesn't make the Person object transactional. You are changing the person object by changing the address -- that change won't roll back. To get what you want you'd need something more like: | if("add".equals(command)){ | Person old = ((Person)cache.get("/test/p1","p1")); | Person clone = (Person) old.clone(); | Address oldAdd = clone.getAddress(); | Address addClone = (Address) oldAdd.clone(); | addClone.setCity(value); | clone.setAddress(addClone); | cache.put("/test/a1","a1" ,clone); | | if("pp".equals(key)){ | System.out.println("Gettttttttttttttbefore:a1=" + cache.get("/test/a1","a1")); | throw new Exception("throw exception for rollback"); | } | | } Usual warning that above code is for illustration, may not compile, etc. To have changes to your objects be transactional, you'd need to use PojoCache and instrument your classes.
