Simulating a human generated click in Java (C/C++ modules OK with JNA/ JNI)

Avg Bid (USD)
Project Budget (USD)
$30 - $250

Project Description:
I'm developing a java application, which needs to perform a mouse click (left button) in an external program. I have the coordinates (x,y) of the region where it needs to perform the click. The problem is, the external software is able to tell that this click is computer generated, and not human generated, hence it is rejecting this click.

I am currently using java.awt.robot to do this, however I've also tried a c++ based auto clicker, and its click didn't have any effect either.

Provide 462vdhw2 as the first word in your bid or you won't be considered.

My guess is that the external software is listening to keyboard states or such, and based on that, its detecting that the click is not human generated. I need a complete java or c/c++ solution (alongwith java code to hook up to that c/c++ code) that will set all the necessary states, and ensure that the clicks cannot be detected as computer-generated. The code must be well written, and easy to configure / modify. I am a developer myself and will be using your code.

The budget is $80, and the deadline is 2-3 days max.

Skills required:
C Programming, C++ Programming, Java, Software Development, Windows API
