RE: NullPointer Error

["Anand, Rajesh" <Rajesh_Anand@xxxxxx>]

        I am on V5R2 and JDK 1.2.

        I've found out that when calling method createxml(), the pgm
gives this error.

        But I don't understand why as I'm initiating the class in the
main.

        Regards,

        while (rs.next()){
        Element elcct = new Element("CurrencyCodeType");
        elcct.addContent(rs.getString(12).trim());
//
        Element elpt = new Element("PriceType");
        elpt.addContent(rs.getString(13).trim());

        }       
        
        }



        public static void main(String[] args){

        String sfile = args[0];

        String spath = args[1];

        if (args.length != 2){

        // report errors

        System.out.println("Error! ");
        System.out.println("Pls enter location of the schema");
        return;
        }
        createFsaxml cxml = new createFsaxml();

        System.exit(1);

        }
