I tried all solutions found in this post and it couldn't help , there is something missing I donno what shall it be may be it is versioning issue or something in the tool itself as I check for every thing is 100% on the right way. find attached illustrative images for all steps, note that everything is working fine on local IReport. thanks in advance
