Very simple question about subreport "null" fields

[archimede76]

Hi all!

My JSP Web application include simply report without subreport, and other report with subreport, all developed in Jasper Report with IReport tool. All simply report work perfectly in local and in remote, the other report (with subreport) work perfectly in local (see attach 1_right_local) but wrong in my remote server (see attach 2_wrong_remote). Why?

(very thank all! I send the 2 attach file and the servlet of pdf opening; but i think the problem is not cause from this servlet. I thik, depending another properties or setting in IReport).
