Jython

i have a spring/hibernate based webapp that i would like to try to
port to jython/django.
first thing i would like to do is add jython to this app and create
new page using django templates and forms (without database) just to
check if it works.
i don't have enough time to port entire app (mostly because it's
deployed on ibm websphere and db2 and there is no driver/docs for db2)
so could you provide some tips howto get started only with templates
and forms?

is it possible to combine parts of jython/django to integrate with
existing java apps, in this case spring/hibernate?

Sure! You can, for example, use Django's views/templates/urls.py (and perhaps forms and the others rendering-related helpers) while still using hibernate as the ORM. You will loose stuff which depends on Django's ORM like the Admin and Auth (and perhaps Sessions). There are ways to workaround the problem, but I don't know if this is relevant in your use case. I suspect you just want a simpler way for your app to interact with HTTP and the browser and Django is a good solution for that. -- Leo Soto M. http://blog.leosoto.com

Take a look at the web.xml generated by jython manage.py war. It "mounts" the Django app on "/" (via the ModJy servlet and the application.py shipped on the WAR file). If that doesn't work for your use case, you can modify it so Django is mounted on a different path and then you can share Spring-mapped URLs and Django-mapped URLs on the same web application.
