How to validate a FIX message against Fix dictionary in QuickFix/J?

Question

If validation is on in QuickFix/J, the received FIX message is validated against the FIX dictionary configured for Fix engine.

ValidateIncomingMessage| Allow to bypass the message validation (against the dictionary). Default is "Y".

Is there any utility class or method present in QuickFix/J which provides me this functionality to validate a sample Fix message against a Fix dictionary?

You want to use DataDictionary.validate()

            DataDictionary dataDictionary = new DataDictionary( pathToDictionary );
            Message quickfixMessage = new Message( message, dataDictionary );
            dataDictionary.validate( quickfixMessage );

where message is the fix message. QuickfixJ includes some dictionaries in the etc folder.

If you have a specific String that you would like to validate, quickfix.Message has a constructor that lets you do this:

public Message(String string,
       DataDictionary dd,
       boolean validate)
        throws InvalidMessage

And can be used like this, for example.

DataDictionary myDict = new DataDictionary(dictionaryPathHere);
Message myMessage = new Message(messageString, myDict, true);
// If this doesn't throw an exception, the message was successfully validated against the dictionary.

This will only validate repeating groups in the message against the dictionary then validate the checksum. It will NOT validate non group fields against the dictionary. – Alex Colomb Jun 24 '20 at 20:17
