If you need to add fields to the logon message when you initiate a session, do it in the toAdmin callback of the Applicationinterface. For example, a counterparty may ask to have a user identifier placed in the SenderSubID field and a password put into the RawData field.
In the toAdmin callback, if the message is a logon message (being sent to the counterparty) then add your fields. The sent message will include whatever changes you make to the Logon message in the callback.

Is QF/J able to accept custom Logon messages created above? Say, how can it be configured to accept a logon with SenderSubID or TargetSubID?
