For what it is worth, I have used Java 7, JPA (with hibernate), tomcat 7 and glassfish, and I didn't notice much difference. Jersey (JAX-RS) is pretty nice, one of the better libraries to come out of Java in a while. I do agree that Java is moving in the right direction, but it is a very slow progression. I think the major cause of the slowness is because of the fact that SUN was bought by Oracle, and it took a little while for that to settle down, and now things are slowly moving forward again. One of the things that Java did right was their WAR files. It is the envy of most other programming languages. You compile your WAR file, and deploy anywhere assuming it is a compliant servlet container. I wish Python had something like this. You are right the popularity of PaaS's like dotCloud make it much easier to deploy and run your application. On dotCloud you just need to push up your WAR file, and you are running, by far the easiest of all the languages to deploy. I really like Java as a language, I just think it has a long way to go on the web application front, before it can catch up to the features and speed of development of the other languages.
