SAP GUI for Java auto login

Any desktop programmer can write a simple script to login via SAP GUI for Java automatically!

If you want to skip instructions and see a sample Python code, check in my pet project Kutapada.

Step 1: Dynamically create a string with the following format:


Here is an example:


If you aren’t familiar with that connection string format, check this article.

Step 2: Save this string as a text file with the extension .sapc . Example file name: login.sapc

Step 3: Let your OS open this file, as if the user double-clicked. If your file associations are accurate, SAP GUI for Java will read this file and log in automatically.

Step 4: For security purposes, delete the generated .sapc file. Otherwise, you will be storing your password in an unencrypted text file.

        Javanın SAP Gui sine odaklı olunca sizin Py uygulama yerine java gui ile denedim bu hatayı aldım. Şimdi sizin gitteki py uygulamayı çalıştırmaya çalışıyorum. Py de çok fazla bilgim olmadığı için henüz çalıştıramadım.
