Is there a way for jasper report/ireport to query data from multiple flat file and display them on report?

Question

i try search through this and come up with no result,it look like jasper report let you pass only one csv/flat file as its datasource.Is there a way to supply it with multiple flat file and query them like normal db table? I don't want to keep those data in db first because there are ton of them and store those data in db look unnecessary

thx for your answer :)

I'd suggestion that you'd have to write your own data source tat was capable of reading from the required files.

Alternatively, you read all the data in yourself & pass into jasper as a List
