xmlerrorhandler<object> errorhandler=new xmlerrorhandler<object>(logfilelocation);         logfilename=errorhandler.getlogfilename();         validator.seterrorhandler(errorhandler);             validator.validate(source);

i creating log file inside xmlerrorhandler constructor since point have control here code log file creation

fileappender appender;             try {                 appender = new fileappender(layout, sb.tostring(), false);                 log.addappender(appender);                 log.setadditivity(false);                 log.setlevel(level.warn);             } catch (ioexception e) {                 e.printstacktrace();             }
