private void checkReviewLength(Errors errors) { ValidationUtils.rejectIfEmptyOrWhitespace( errors, "review , "required , "Review text is required ); if (review != null && review.length() > 10000) { errors.rejectValue("review , "too_long , "The review you entered is " + "a novel in itself; please try " + "to shorten it ); } } Programmer: There s a bit more to this method, as it s doing two checks on the review. The first check is unchanged from the previous version it s using a convenience method in ValidationUtils to add an error to the list if the review text is empty. Then after that we do a manual check to make sure the review text isn t too long. Reviewer: You might want to move the 10,000 literal into a constant. Actually, I notice you didn t include some of this detail in the sequence diagram, but we ve broken the back of this now, so let s move on. Programmer: OK. Here s the last of the four new methods, checkRating(), which makes sure that the rating is between one and five: private void checkRating(Errors errors) { if (rating < 1 || rating > 5) { errors.rejectValue("rating , "outofrange , The rating must be between 1 and 5 ); " } } } Reviewer: Good! Without this, the user would have been able to enter 0, or indeed any old value.

If you ve ever used a stock quote service over the Internet, you ve probably noticed that the example so far is somewhat simplified The GetStockQuote() function returns one piece of information a price quote whereas popular financial sites usually produce a full quote with a 52-week high and 52-week low and other information about the volume of shares traded on a particular day You could add more methods to the web service to supply this information, but that would require multiple similar function calls, which would slow down performance, because more time would be spent sending messages back and forth over the Internet The client code would also become more tedious A better solution is to use a data object that encapsulates all the information you need.
