A number of people are using POI for a variety of purposes. As with any new API or technology, the first question people generally ask is not "how can I" but rather "Who else is doing what I'm about to do?" This is understandable with the abismal success rate in the software business. These case statements are meant to help create confidence and understanding.
We are actively seeking case studies for this page (after all it just started). Andy Oliver (acoliver at apache dot org) has agreed to have a few T-Shirts printed with the POI logo (once its chosen) for the first few best submissions. To submit a case study, either submit a patch for this page (preferred) or email it to the mailing list .
Edwards and Kelcey Technology (http://www.ekcorp.com/) developed a Facility Managament and Maintenance System for the Telecommunications industry based on Turbine and Velocity. Originally the invoicing was done with a simple CVS sheet which was then marked up by accounts and customized for each client. As growth has been consistent with the application, the requirement for invoices that need not be touched by hand increased. POI provided the solution to this issue, integrating easily and transparently into the system. POI HSSF was used to create the invoices directly from the server in Excel 97 format and now services over 150 unique invoices per month.
