Reading CSV or Excel files in java and mapping values to database columns

Dear colleagues,

I am looking for a free and simple mechanism for reading data from
files (could be CSV or XLS ) and inserting values that are read into a
database. I know that I could import a csv/xls file directly from a
database, but this is different. There is a Document Management
System in the mix. The use case is like this:

1) User creates csv/xls file with certain information ( i.e:
"male,usa,hispanic,married")
2) Java program reads file and maps string values to attribute
properties in the DMS

I've seen the Apache POI and a few other (Oster utils, etc) but I
haven't found something simple and flexible enough to allow me to
incorporate business logic as well as basic file i/o and string
manipulation.

If you have any information, tips or advice, I would greatly
appreciate it.

Kind regards,
Fer
