To my surprise, there were no existing, freely-available, open-source IIF libraries for Java. This library attempts to fill that void.
This library can be used to write out IIF files that can be imported into QuickBooks 2007 and later editions.
Check out src/com/redbottledesign/accounting/quickbooks/examples for some practical examples of
using this library.
