[rules-users] Getting the Fact type for Declared Types

[Srinath Perera]

Hi All,

I have declared type (rules are given below), and I want to access it
through  kbase.getFactType(...) see below.

===== Rule  =============
package sample1

import java.util.Date

declare Person
    name : String
    dateOfBirth : Date
    address : String
end

============ Code =================
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();

        KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
        kbuilder.add( ResourceFactory.newFileResource("src/ruleset1.drl"),
                      ResourceType.DRL );
         kbase.addKnowledgePackages( kbuilder.getKnowledgePackages() );


         StatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();
      // get the declared FactType
         FactType personType = kbase.getFactType( "sample1", "Person" );

============================================

But personType returned by kbase.getFactType(..) is null. Could anyone
know can give me a hand?
