[rules-dev] Error unmarshalling KnowledgeBase

[nestabur]

Hi all,

I'm getting 2 different errors trying to unmarshalling 2 different KBases:

1: org.drools.RuntimeDroolsException: unable to determine operator for
symbol [after]
2: java.io.StreamCorruptedException: invalid stream header: 776CACED

The 1st one seems to be caused when using the operator after in the DRL, so
the marshalling/unmarshalling strategies dont support CEP rules?

The 2nd one could be caused because of using different marshallers ... but I
use the same!!

My marshalling methods are:

	public void save(FileOutputStream out) throws IOException{
		
		DroolsObjectOutputStream droolsOut = new DroolsObjectOutputStream(out);
		droolsOut.writeObject(ksession.getKnowledgeBase());		
		Marshaller mas = createMarshaller(ksession.getKnowledgeBase());
		mas.marshall(droolsOut, ksession);
	}
	
	public void load(FileInputStream input) throws IOException,
ClassNotFoundException{
		
		DroolsObjectInputStream droolsIn = new DroolsObjectInputStream(input);		
		KnowledgeBase kbase = (KnowledgeBase)droolsIn.readObject();		
		Marshaller mas = createMarshaller(kbase);		
		ksession = mas.unmarshall(input);
	}
	
	private Marshaller createMarshaller(KnowledgeBase kbase){
		ObjectMarshallingStrategyAcceptor acceptor =
MarshallerFactory.newClassFilterAcceptor(new String[]{"*.*"});
		ObjectMarshallingStrategy strategy =
MarshallerFactory.newSerializeMarshallingStrategy(acceptor);
		return MarshallerFactory.newMarshaller(kbase,new
ObjectMarshallingStrategy[]{strategy});
	}
