Hello everyone. I just encountered new problem. before this my jasper report is okay. but then i changed the directory of my file but moving my project into a new folder. sub-folder in my project. im using netbaens and using jsp. before this, there is no problem at all to generate the report, but then yesterday, after i did the moving all files, when i try to generate the report, it return error:null. i have check all libraries and everthing. im using jdk 7. my jasper report plug in is version 5.6.0 and it is the same as my jasperreport.jar 5.6.0. i have tested all the path at my path which something like this
File reportFile = new File(application.getRealPath("..//reports//test.jasper"));
i have tried so many time changed it to many possible path but is seems to get error
