JasperReports and Web Application

[phillips1021]

I'm able to get the web application demo to run just fine. However, that demo just uses a single report. I need to have a main report and a sub-report in my web application.

 

But when I add a sub-report to the main report that uses an new JRBeanCollectionDataSource as the datasource expression I get an error:

 

javax.servlet.ServletException: javax.servlet.ServletException: Error evaluating expression : Source text : new JRBeanCollectionDataSource($F{phones})

 

The JasperReport main and sub-report works fine in iReport. They also work fine in just a plain java application.

 

Any help would be greatly appreciated on how to use a sub-report with a main report in a web application.

Thanks to some great help from Dave Newton, I was able to figure out how to use Struts2, JasperReports, a main report and a sub-report in my web application.

 

I blogged about how I got it all to work here:
