[TM4J-users] Problem adding topic map to provider

[<Fro...@id...>]

Hi. I'm trying to figure out this TM4J. I'v just tried to make a
TopicMapProvider and add the "kings_and_queens" topic map. Like this:

			 TopicMapProviderFactory tmpf = TopicMapProviderFactory.newInstance();
			 TopicMapProvider provider =
tmpf.newTopicMapProvider(System.getProperties());

			 TopicMapSource source = new
SerializedTopicMapSource("C:/Diplom/tm4j-0.9.7/examples/topicmaps/kings_and_queens.xtm");
			 TopicMap tm = provider.addTopicMap(source);


When I run this program I recieve the following error:

Exception in thread "main" java.lang.AbstractMethodError:

I recieve the same error when trying to run the "Stats" example that
follows TM4J.
