In a trivial setup it's pretty easy to get the jvm up and running, but making a good cached deploy of apache httpd fronting tomcat and a database server isn't very easy. It's not very easy to set up a server with rails either (easier these days but still a pain if you're a noob). I'm not sure how easy something deploys is critical for the value of a platform. Developers should understand how stuff are deployed but it's not necessary that they know how to do it correctly, nor should every developer deploy their own applications. (I mean, it doesn't hurt if they know how to do it, but it's better that developers spend their main time developing not minding the server farms).
