According to the javadoc comment for the disconnect() method you should rather not call it from user code:
* This method should not be called from user-code since it is likely
* to deadlock when called from a different thread than the Session thread
* and messages are sent/received concurrently.
* Instead the logout() method should be used where possible.
So please use the logout() method to log out from a Session. It will also disable the Session in a way that counterparties will be logged out when connecting. But there can be a short timeframe when they will be logged on. This is because that flag is only checked once a second.
To reject a Logon right away, you could throw a RejectLogon Exception out of your fromAdmin() callback.
I am expecting a mechanism to manually logout and stay logged out (in other words stay disconnected) until manually allow to logon. But, when I try the logout() method, if the counter party tries to logon then system allowing it. I tried to set a RejectReason while I'm manually logout() in order to throw RejectLogon as you mentioned, this message was not available when the Logon request received. So, I cannot maintain the session logged out.
To throw
RejectLogonyou need to really throwRejectLogonout offromAdmin()as I mentioned. It won't work to throw it fromlogout(). So first calllogout(), then put a check into yourfromAdmin()to throwRejectLogonwhen aLogoncomes in. That will reject incomingLogons.Before i throw the
RejectLogonfromfromAdmin, i want to make sure this logout is imposed manually. So, i would like to validate theLogoutReasonfor the corresponding session'sstate. But, it is getting nullified before it reach to the methodfromAdmin(). Any idea to handle this situation?You mean you only want to throw
RejectLogonif you formerly decided to logout manually? Can't you store a boolean flag somewhere in your application? And then simply check if that boolean flag has been set totrue? Or did I misunderstand you?We can go for the boolean flag suggestion @ChristophJohn. Thanks a lot for the suggestion.
