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 sap_connection.py in my pet project Kutapada.

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

conn=<CONNECTION>&clnt=<CLIENT>&user=<USER>&pass=<PASSWORD>&lang=<LANGUAGE>&expert=true

Here is an example:

conn=/H/10.1.3.122/S/3200&clnt=100&user=KEREM&pass=SECRET&lang=TR&expert=true

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.
