AutoIt + Java integration Exception Handling

[nares]

I am trying to automate login application (.exe) using Autoit and java integration. 
As a part of this automation i am able to login successfully but other part i want to check
Login Failure case where username/Password given by user is incorrect, 
So how can we detect Login failed part or any way to  handle Exception in this case.
