Understanding Jasper and Hibernate Reports and Parameters

Question

I'm sorry this is a bit of a bad question, since my problem is that I just don't understand what approach should be taken for this. I have this hibernation database that works great, and I want to use JasperReportsto create reports based on data from it. I have a iReportworking and connected to the configuration hibernateand able to read fields from my queries and build a report.

However, I want to be able to save reports run from my application and to certain objects that are solved at runtime. I need to be able to pass my custom persistent objects to these reports at runtime and generate reports this way. so they really don’t need a request, they just need to know what objects they are going to receive.

I see that I can give them parameters, but only raw objects, and also in iReport, I can only make fields from simple data types, but most of my values ​​are displayed in toString () of my objects, so I would just like to return them.

I would be incredibly grateful if someone would explain some of these things to me. Thank you very much! Joshua

I think you might have to look for http://jasperreports.sourceforge.net/api/net/sf/jasperreports/engine/data/JRBeanCollectionDataSource.html

it's a beans data collection, so you can load custom beans into a report as a data source
