Python/Selenium code to open an application and login ( GUI Automation)
If the Java application is using DB (it almost certainly does) you can try getting the data from there directly instead of extracting it from the GUI.
Am working on a project where i need to gather information from different websites ( Internal to company) and also few information from an windows  application developed in Java.
I was able to pull all the information from websites using Selenium/Python, now I have an Window application where i need to fetch some information. Since selenium is not supporting Window application am not able to continue with that. I tried using AutoIt but my application is developed on JAVA and autoit windows spy is not able to detect many buttons on the application.
Any suggestion/Idea based on your experience how to proceed further ?
I have 80% of my information in websites which I have already scripted to pull only pending is this applications.
