QuickFIX/J how to disable auto logon response

I'd like to perform some operations after receiving LOGON message and then decide if LOGON failed or not (for example check username and password) but... Immediately after receiving LOGON message QuickFIX/J resends:

8=FIX.4.4|9=74|35=A|34=13|49=FIXserver|52=20110831-09:27:41.847|56=localhost|98=0|108=10|10=131|
8=FIX.4.4|9=71|35=2|34=14|49=FIXserver|52=20110831-09:27:41.855|56=localhost|7=1|16=0|10=213|

How to disable this functionality?

Sec开发者_如何学Goond question. If LOGON failed, should I resend LOGOUT message or something else?

Call you required methods which do your logon checkins and other checks in onLogon. You can disable sending messages in toAdmin. Entry points for messages is fromAdmin and sending point is toAdmin.

No need to send logout message as logon didn't happen. You logout out of a session only if you have logged in.
