Can we automate mainframe applications apart from screenshot function

You seem to know, what you are doing: just try it.

Keep in mind: SikuliX is all about pixels seen on a screen.

Thank You RaiMan. But its just like i only don't need to work with pixel and screenshots. I also need to capture the text from screen and paste it in my script. So just want to check if its possible using Sikuli.

Be aware of the known weaknesses of the text feature in actual SikuliX (Region.text())

To check wether the text you want to have can be read correctly, just run this oneliner in the SikuliX IDE:

uprint(selectRegion().text())

this will allow you to select a region containing text and watch the result.

take care, that at best only the area containing the text is selected.

If it is not satisfying, then you have the option to use the commandline Tesseract directly (using stored images and subprocesses).

If you are in Java or Java aware environments, Tess4J is surely an option, since it relies on Tesseract 3 allowing the available options to optimize the results. Same goes for the Tesseract command.

Thanks for the answer. One more thing is there... What is OCR Jar that we use in eclipse for sikuli??
I want to perform validations like if username is already entered it should not enter the username again else it should enter

the text features are all builtin in SikuliX 1.1.2+

see the docs.

I am not using the IDE, i am using jars in eclipse.

I know, I am talking about sikulixapi.jar.

Will it be able to capture unique values every time after a run?

You should really at least read once through the docs, have a look at the java API and simply try things.

The before mentioned question is not clear anyways.
