Quick question, do you have "error.jsp" in your /WEB-INF/view/jsp/ folder? Also, in your first method (TestController.testStringResult()) you misspelled "redirect", which will also result in 404. Also, take off the leading "/" for the testModelAndView() and testString()...you're effectively looking for / WEB-INF/view/jsp//error.jsp (which should still resolve, but is not necessary and clouds up the code a bit)
