So would I - a "Spring for Django devs" article would be pretty useful too.
A much better way would be to have an universal standard, possibly abstract framework with which all frameworks are contrasted. This way, only n comparison articles need be written, giving a linear cost.
Sorry, could not abstain. OTOH, this principle is mighty useful when writing conversion software. Just write converters to and from a standard format.
I would be eager to read such an article too.
In the average JEE project, that's all you'll be using as far as Spring goes. Or maybe add Spring Integration or Spring Batch.
