Passing Collection to Report

2004-08-13 06:53

Hi,

 

I am trying to pass a collection to the report, but not successful. I am not even sure what is the parameter be in the xml file (using iReport to design it) and in the my class, would I just be something like this?

 

bytes = JasperRunManager.runReportToPdf ( reportFile.getPath(), parameters, collection);

 

Any help or suggestion is greatly appreciate?

In this case you need to pass a JRDataSource as the 3rd parameter, so you need an implementation of this interface which treats each item in your collection as a record & maps the field names in the report definition to the appropriate methods on the collection elements.

 

Have a look at JRBeanCollectionDataSource, which uses reflection to map a field name to a property getter method.
