the relevant springer policy states that you can post a preprint version of the paper anywhere including arxiv.org but not the final version. Springer also has a program called open choice in which you pay sprnger $3000, and in return, they will make the final pdf wersion of your paper avaiable on their sever for free for anyone with web access.
