[JasperReports and 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:

In that blog entry you can download a complete war file with source code including the .jrxml files.

[JasperReports and Web Application]

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.

[Subreport and Struts2 problem]

I'm having a similar problem getting Struts2, JasperReport, JasperReport plugin for Struts2, and a JasperReport sub-report to work.

 

Did you ever solver your problem and if so how?

[Using ArrayList of Objects As The Data Source]

I finally figured out how to use as the data source for a JasperReport an ArrayList of objects where each object also has an ArrayList as one its fields.

 

Since this seemed to be a question posted quite frequently and since there did not seem to be a very good tutorial on how to do this (or at least not one easily found), I created an extensive tutorial on my blog.

I hope my blog entry will be helpful to others who needed to use an ArrayList as the data source for a JasperReport.
