Yes I have the same problem. I have a well working program, which uses JasperReports. It uses JRBeanCollectionDataSource(List items); to populate the rows with data, but if I compile the .jrxml file either with JasperCompileManager.compileToFile() or with iReports I see only parameters populated without rows. Does anyone have had such a problem

I think you had forgotten to put <detail> element in your .jrxml file. Is it so?

 No im using all those..... That report is executed and generate while i run in main() method.... /tools/fckeditor/editor/images/smiley/msn/regular_smile.gif   but while i execute from server the blank page will appear....

you can see jrxml file

Hi,

 

This is not a proper way to deliver PDF to the browsers. Some browsers want to know in advance how many bytes will be sent to them on the response stream.

You should better take a look at the /demo/samples/webapp sample provided with the JR project and learn how to use the PdfServlet class from JR, or get some inspiration from its source code.

 

I hope this helps.
