"Document has no pages" on iReport and nothing on OpenReports

Question

I am having an issue with JasperReports I can not solve. I am using Eclipse, OpenReports 3.2 and IReport 3.7

The issue I am having is that the report does nothing. When I preview the report in IReport I can at least get a "Document has no pages" message but when I try to open it using OpenReports it doesn't do anything. I get the open reports header and the copyright message but nothing between them.

I was able to track it down to line 150 in ReportRunAction.java in OpenReports. That line is:

jasperPrint = jasperEngine.fillReport(reportInput);

At least that is the line the page dies on. It trips the catch block that the line is inside of but the error is empty. When I try to print the description it is null. I can't swear that the issue isn't that parameter. Through looking around all I have been able to find is something about how the report needs to be compiled with the same version of the jasperreports.jar that OpenReports uses. I have no idea how to tell if/what version of jasper reports is being bundled into the .jasper file though.

Is that my problem? If so how do I tell/set the version of the jar that gets bundled? If not; help!

Answer 1

The no pages messages comes out when the report has not records or you discarded all of them with a wrong filter expression.

There are a couple of things you can try:

1. set the filter expression to:

   new Boolean (true)

This will in some way reset your filter expression.

• Right click your jasper report

• properties

• find more...

  and Set the report property "When no data" to "All sections no details" so you can see at least the rest of the report.

Thanks.
