public abstract class JasperReportsUtils
extends Object
```
Utility methods for working with JasperReports. Provides a set of convenience methods for generating reports in a CSV, HTML, PDF and XLS formats.
This class is compatible with classic JasperReports releases back until 2.x. As a consequence, it keeps using the JRExporter API which has been deprecated in early 2014.
