Someone knows where I can find a sample of an application jdeveloper executing a jasper report?
I have imported jasperreports.jar and i tried the code bellow, but it gives an error message - java.io.FileNotFoundException: FirstJasper.jrxml
The file is in the same directory as my class. but it doesn´t work.....
please I need help..
