3. What is ?
• http://jasperforge.org/projects/jasperreports
• “world's most popular open source reporting engine.”
• “entirely written in Java”
• “use data coming from any kind of data source”

4. Feature Highlights
• Pixel-perfect page-oriented or continuous output for web or print
• Traditional tabulated data, multi-level grouping and data aggregating by group
• Dashboards, tables, crosstabs, charts and gauges
• Report output in PDF, XML, HTML, CSV, XLS, RTF, TXT
• Integrated barcode support
• No limit to report size
• Conditional printing
• Sub-reports handle highly complex layouts
• Multiple data sources of multiple kinds in one report
• Internationalized and Localizable
• etc., etc.

5. Flexible Data Sources
• JRDataSource interface
• Database JDBC connection
• File CSV data source
• XML file data source
• etc., etc., etc.
• Custom JRDataSource
• KeyValueCoding objects

9. 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 :-)

10. Planned Improvements
• Batching and EOEditingContext recycling for huge data-sets.
• API for subreports
• Planned before end of the year

12. ERJasperReports Usage - Typical Logic
Pre-Requisites Create the
EOFetchSpecification
Create
1. report.jasper file in LongResponse Page
Resources
Optionally create the
2. ERJasperReports in Parameters HashMap
the classpath Run Background Task
Create
ERJasperReportTask
Download the Report

13. Report Design Tool
• iReport.app
• http://sourceforge.net/projects/ireport/files/
• iReport.dmg installer for OS X
• IMPORTANT: iReport version must match JasperReports
• JasperReports dist bundled inside iReport.app
• Current version is 3.7.4

• Best available (IMHO), to get you started...
• “jasper Reports 3.5 for Java Developers” - amazon.com
• Also....
• JasperForge.org (you probably need a free account)
• intros, tutorials, forum, etc.
• Down load source. See readme.txt, demo, dist/javadoc,
