JRPropertiesUtil (JasperReports 5.0.1 API)

java.lang.Object
- net.sf.jasperreports.engine.JRPropertiesUtil

```
public final class JRPropertiesUtil
extends Object
```
Class that provides static methods for loading, getting and setting properties.
The following actions are performed:
- The default (hardcoded) properties are set.
- If the system property "net.sf.jasperreports.properties" has been set then the specified proprties file is loaded.
- Otherwise "jasperreports.properties" is loaded if found in the classpath.
- For backward compatibility, system properties like "jasper.reports.compile.xml.validation" are checked and their values are used. This way of specifying properties is deprecated.
