question: public static ExceptionMessage translateExceptionMessage ( String code , Dictionary < ? , ? > params ) throws MessageTranslatorException { MessageFormat mf = lookupMessageFormat ( code ) ; String [ ] indexNames = lookupArrayIndexNames ( code ) ; String fieldRef = lookupFieldReference ( code ) ; String newCode = lookupCodeName ( code ) ; Object [ ] formatParams = new Object [ indexNames . length ] ; for ( int i = 0 ; i < indexNames . length ; i ++ ) { Object param = null ; if ( null != params ) { param = params . get ( indexNames [ i ] ) ; } if ( null == param ) { formatParams [ i ] = "" ; } else { formatParams [ i ] = param ; } } String message = mf . format ( formatParams ) ; if ( fieldRef == null ) { return new ExceptionMessage ( new ExceptionCode ( newCode ) , message ) ; } else { return new ExceptionMessage ( new ExceptionCode ( newCode , fieldRef ) , message ) ; } }
target:  This is the same as the translateExceptionMessage method that takes an exception code, except it takes a string representing the code to use to look up the message from the file
