[Kamal Thiyagarajan]

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
