I've been working for about 5 years in Java, developing financial back-offices (web-services, business logic, report generation etc.).
I think Mathematica is very suitable for such calculations and business logic development and am wondering if there are any success stories for its usage in such systems.
I also think that it can be pretty to use Mathematica with JLink in my web-application to delegate calculations.
- Does anyone have such an experience or know-how ?
UPD 1: Removed some questions (they have relation to Wolfram Workbench):
What about unit-testing in Mathematica ? How to organize Mathematica code if it would be very large ?
