In the given example, the jacket belongs to James. So, when writing the possessive noun or nature of the jacket, it should be written as James' jacket. The positioning of the apostrophe symbol (') right after the -s in James is due to the fact that the word ends with an -s. So, there is no such need to rewrite or use -'s for James. In other words like Andy or John, the words do not end with an -s, so the possessive noun for them will be written as Andy's/ John's. But in the case of names such as James that ends in an -s, the -' symbol will come after the -s in the name.
