Class JRPropertiesUtil

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.
