I have no experience with the JDO stuff, so I can't comment on it.

How big exactly are the numbers that you are dealing with in your data entry
fields that they don't fit into a regular integer (+/- about 2 billion).
And the long use in BigInteger & BigDouble would be strictly for performance
reasons.  You should be able to (carefully) replace them with ints & it'll
still work, albeit more slowly for bigger numbers.

There's plenty of stuff out there about how to emulate big integers (it
really isn't that difficult to do - but difficult to get right with good
performance).

Yes - that is the correct approach that should be taken when dealing with
important data - let the server deal with parsing it.
