Develop in Django+Python, deploy in Java.
django-jython includes a “war” management command so you can […] get a single mysite.war file which you can deploy in your preferred application server. This file doesn’t require anything special installed on the target server. No Django, no Jython, no nothing.
Do I get it right? I develop using whole smoothness of Python and Pony powers of Django. And then, thanks to Jython and django-jython, I can magically generate a native Java web application for deployment on enterprise web servers? Wooow, I’m impressed. This way both developers and administrators are happy :)
More about django-jython. Currently already works with Django 1.0.x and several database backends. And more updates coming soon. Cool!
