Evictor.Builder expected in the config object?

[naditina]

Hi,

I'm trying out a 2 weeks old snapshot version of ELK. When I try to load a reasoner with any ontology, I get a null pointer because an Evictor.Builder object is expected in the config object.

at org.semanticweb.elk.reasoner.tracing.TraceState.(TraceState.java:184)

Setting a String value in the ReasonerConfiguration object does not help because the value is expected to be of type Evictor.Builder.

How can I resolve the problem?

Thanks
Nadeschda

Is there any particular problem you whant to solve? Why do you need a custom configurations? I think most of ELK settings can be changed using java properties.

Yes provided it is on the classpath. You can also supply the values using java command-line options -Dproperty=value.
