Thanks! I used ShipmentReport.jrxml and ProductsReport.jrxml as base for my prototype. But, they are based on SQL statement, not JRDataSource... So, I used this resource instead to get my report works http://broschb.blogspot.com/2008/05/dynamic-jasper-report-using-crosstabs.html

Yes, I'm using subdataset... And I'm getting 3 blank pages. I can see vertical lines for each row at the far right side of the page, but there is no data... Log4j shows that my JRDataSource implementation been called for each element... So, I'm pretty sure that report is filled with data. But PDF, CVS, XLS exporters return blank pages....

Lucian, I've seen this FAQ. This is not exactly that I want. I would like to have my JRDataSource driven Crosstab in Detail section instead of Summary... Is it posible or not? So far I haven't succeed.

Anyone??? I need help with this!

I'm using Velocity for my report. Hint! I noticed that Velocity engine mistranslates Jasper's parameters while processing template. My workaround is to set Velocity variable and pass value to Jasper Parameter/Variable.

Please consider to use JRFileVirtualizer while you are filling out your report. Then you can use JasperPrint object for your exporter. There is my code example: Code: Post Edited by sergeleo at 09/04/2009 01:01 PM Post Edited by sergeleo at 09/04/2009 02:42 PM

I have Crosstab report based on JRDataSource implementation. And when I was trying to put Crosstab into Details section, my report was always producing blank pages with no data... When I moved Crosstab into Summary section, my report comes out just fine, filled with data. Based on logs my JRDataSource implementation always been called from Details and from Summary. But only when my Crosstab in Summary section, my report renders data. I was looking through the forum and also I was googling for samples with implementation of the JRDataSource and Crossdab and so far I was able to find only few examples where Crosstab resides in Summary section. I wasn't able to find any example with JRDataSource and Crosstab in Detail section. So, is there any paerticular reason why it's not working? I'd like to take advantages of Page Headers and Footers in my report, but I can't unless I'll move my crosstab out of Summary... Please share your experience!

Looks like I cannot use Connection and JRDataSource in same report....

Thank you for your response! I don't have any query in my report since I'm using JRDataSource implenetation. But I like your workaround! I'll try to put SELECT 1 FROM DUAL as a main query and my fields to subquery..

Thank you Teodor. Actually I did, but since my crosstab report already in the summary section I haven't relate this to my case. Could you please provide some examples for those fake titles and summaries? Thanks! Serge Post Edited by sergeleo at 08/26/2009 06:00 PM

Hello everybody! I'm new on this forum, so please be kind :) I have Crosstab report for my project. I'm using JRDataSource and since I wasn't able to find any other way to make it work, I put Crosstab report into Summary section. Also I have predefined page header and page footer with various information (mostly images). So, since there is a lot of data in report and crosstab has been extended to second page I was expecting to see page header and page footer on second page as well. But it wasn't printed at all; even worse, crosstab report on second page was aligned to the top leaving no space for page header. Any thoughts?
