[rules-users] issue with .drl file to .brl file conversion

[Amninder]

i am trying to do the same thing but shows 
		String fileName = "D:/DROOLS/test/BRLtest/src/main/rules/myname.brl"; 
        File file = new File(fileName); 
        String empty="";
        String fileAsString=""; 
        fileAsString = FileUtils.readFileToString(file, empty); --->i need
to pass 2 parameters 
                                
        BRXMLPersistence read = (BRXMLPersistence)
BRXMLPersistence.getInstance(); 
        BRDRLPersistence write = (BRDRLPersistence)
BRDRLPersistence.getInstance(); 
                      
        String outputDRL = write.marshal(read.unmarshal(fileAsString)); 

        System.out.println(outputDRL); 

thus is there some error with the readfiletostring() methid being used.
ALso can you help me with the deployment of Drools  BRMS.war .
