What is in ERJasperReports

• jar libs for JasperReports and its essential dependencies

• Custom JRDataSource for array or enumeration of KVC objects.

• java.util.concurrent.Callable task operating on a EOFetchSpec

• Convenience utility method for calling JR.

• Add the framework to your project. Has Wonder dependency

• Not yet committed to Wonder :-(

• Should be within a week :-)

Planned Improvements

• Batching and EOEditingContext recycling for huge data-sets.

• API for subreports

• Planned before end of the year

Create the EOFetchSpecification

Optionally create the Parameters HashMap

CreateLongResponse Page

CreateERJasperReportTask

Pre-Requisites

1. report.jasper file in Resources

2. ERJasperReports in the classpath

Download the Report
