A company i used to work for replaced all CGI scripts with JSP ("um, have you considered mod_perl instead", "oh well, um, a-hem, um, we need JSP!"), and the site looks the same and runs about the same. Personally, i think that was a big waste of time. Starting from the ground up in JSP would be okay, but i really think a company needs to understand WHY they HAVE to use JSP. The main reason i can think of is that their programmers are really less than average. ;)
