I am trying to create a Pentaho metadata Domain using the Java class </pentaho-metadata/src/org/pentaho/metadata/automodel/AutoModelerScenario.java>. When creating an Data Model using Pentaho automodel API, I run into an exception. Please suggest how to resolve the exception:
Root cause: Code referenced from Props.java at <http://trac.spatialytics.com/geokettle/browser/trunk/src-core/org/pentaho/di/core/Props.java>. However Props constructor is protected, not public , so I can't instantiate it.
The exception is:
I have executed this
. The kettle.properties file is empty.

Code:
public static Props getInstance()
{
if (props!=null) return props;
throw new RuntimeException("Properties, Kettle systems settings, not initialised!");
}The exception is:
