I have to disagree with that experience - probably each to their own - python certainly has its limitations. I only started using python for GAE - being a J2EE guy for way too long (still). I am enjoyng the freedom of things like closures, instant gratification (change the server code, refresh the browser) and finding the actual delivery of functionality is much faster. Using GWT, it is an interesting paradigm shift having Java for client development, and the non type- safe language on the server. The other thing I am finding is that pushing the MVC to the client means the layer between the HTTP request processor and the database is pretty thin - especially with BigTable/ Data API. So perhaps I don't mind Python because this architecture means there isn't much to do - the server certainly has nothing to do with rendering the view.
A lot of the arguments for the J2EE architecture disappear if you take away MVC, take away EJB, take away RMI, take away hibernate & take away clustering (which GWT+GAE does) - what's really left? Request processing via a simple command pattern, security and data handling. Authentication is external to the app - so you've just got authorisation on the security front. GAE essentially delivers all the complex parts of the J2EE architecture in the actual platform, and makes them not my problem. So I'm not at the head of the queue to get server side java frameworks on GAE, just so we can abstract an fairly elegant API with a heavy one. In the end, I might easily move to a java implementation if it came along - there would definately be advantages - but from my perspective, it is not as important as providing the basic building blocks of the application platform. Not being able to do anything aysnchronous in python *and* java seems the wrong way to go. Maybe that's not the intention, but it would be nice to know. I'm not saying we shouldn't have java, but that we shouldn't have it at the expense of the actual application platform. And I'm certainly not declaring any religous alliegance to Python.
