I need to create a report from Excel file for our company. I've never used Jasper Reports, so I have created a one small test table. At first, I've created a blank page and then data adapter from this table. I've clicked on the "data set and Query editor dialog" and selected the language .xls. There is no any other object in page except of the table. And when I want to do preview it is saying, query language not set. Do you have idea, what I am doing wrong?
