any idea??

Hello I have create a java project, based on the java project provided by Jaspertreport project. (Copy of the demo/barbecue project) From this project I open .jrxml file via iReport. I adapt the template and create a datasource inside iReport. (javabean datasource) 1. When I generate the reporting from iReport I don't have any problem; I see my data. 2. when I generate the report from build.xml via Ant in "demo/myproject", I see my report but all my data are null. have you got any idea why it does not work via Ant? Do I need to define the datasource somewhere? thks Valery

nobodies has an answer? advice?

Hello I have already tested to define the "Use a datasrouce expression" as connection type for the definition of subreport in the master one. I tested it with a JavaBean and csv. Always the same problem Any other suggestoins?

hum step further. I see the title that I have in the colum header I don't see the dynamic detail data. Any suggestions?

it does not seem to be the problem. ssubreport expression : - "c:/temp/report5_subreport1.jasper" ou - $(MY_DIR)+"report5_subreport1.jasper" Any other idea? strech type? position type ? in master? other properties for master or subreports? e

Do I absolutely need to pass any data to the subreport? I don't know. As "connection type" parameter I can choose : don't pass data. the data for the subreport are coming directly from the ds defined in the subreport. Moreover when I run the subreport in standalone, I see the data Which kind of filter?
