Hi,

Don't know if it may help but I've just had a similar error (java.lang.RuntimeException: com.thoughtworks.xstream.mapper.CannotResolveClassException: definitions : definitions) when adding a bpmn2 rule flow file (an XML file) as a BRL resource in a KnowledgeBuilder (no comment... :-)).

My2cts,

Bruno.

Hello,

I had try to convert .brl file to .drl format using java code i got an error in conversion. my java code is

String fileName = "c:/Sampleguide.brl";
            File file = new File(fileName);
            //System.out.println("hello");
            String content = FileUtils.readFileToString(file);
            System.out.println(content);
            BRXMLPersistence read = (BRXMLPersistence) BRXMLPersistence.getInstance();
            BRDRLPersistence write = (BRDRLPersistence) BRDRLPersistence.getInstance();
            //BRDRLPersistence.getInstance();
            String outputDRL = write.marshal(read.unmarshal(content));
            System.out.println(outputDRL);

I got error like this
