With 5CR1 I am trying to create a dynamically declared fact type form Java. I am using RuleAgent as described in .../drools-expert/html/ch05.html#d0e2236 From the RuleAgent I obtain a statefull session. However there seems to be no path to optain the FactType as described in the Expert documentation in section 7.7.4: .../drools-expert/html/ch07.html#d0e3365 // get a reference to a knowledge base with a declared type: KnowledgeBase kbase = ... // get the declared FactType FactType personType = kbase.getFactType( "org.drools.examples", "Person" ); But I can not obtain the KnowledgeBase. I have vague memories about KnowledgeBase being part of the renovated API. So this suggest that the documentation is using a mix of old and new API (on the two locations I have given). -- Ingomar Otter CTO mailto:ingomar.otter@valtech.de Mobile: +49 172 2367867 Valtech GmbH Bahnstraße 16 40212 Düsseldorf Germany Phone: +49 211 179237-0 Fax: +49 211 179237-19 http://www.valtech.de Geschäftsführer: Ingo Kriescher Amtsgericht Düsseldorf HRB48672
