Choosing between Django-Apache and Java-Tomcat for a web application [closed]

Question

In order to develop a web application that can easily scale, provide production stability, is easily deploy-able, and allows for fast development cycles, what points would you recommend I look at before choosing one or the other framework - using Java and Tomcat, or Django and Apache/Mod_WSGI?

Some pros and cons I could see immediately,

• Tomcat apps are simple to deploy - drop a WAR file and you're done. Django apps seem to need more wrangling (Not sure if creating .egg files and dropping them in would work as well?)
• Django's ORM seems much nicer than Hibernate - generates models directly compared to Hibernate's manual configuration files
• Python as a language is faster to develop in, and much more concise than Java can be. (Of course, this is a relatively higher level discussion).

I've looked at Disqus's slides about scaling Django and am under no doubts it can be done. But would scaling a Django app be any harder than scaling a Java/Tomcat one?

I'm familiar with both Java and Python and the frameworks mentioned above, and it boils down to getting feedback those who've worked with either (or both) on scale.

Thanks!

Here are my experiences:

• Django-Apache fits in 16MBs of memory, whereas Java-Tomcat requires much more than that.
• Coding in Python is much faster, that is true. In Java, on the other hand, you have compile-time checks, profilers and debuggers that help you increase the stability of your application.
• If you are planning to do heavy computations or need complex data structures, Java's compilation technologies will provide the speed you need.
• It is easier to maintain a large project in a strictly object-oriented environment with advanced refactoring tools, such as Java.
• Then again, coding in Python is much faster.
