Password protect a PDF file

This code will generate a PDF based on a smartform and will encrypt it with a password.

Some prerequisites are necessary:

1. It is necessary to upload the jar (available here) to the application server either using the server filesystem or using the tcode CG3Z.
2. Create a custom command under SM69 (Fill in the correct path to the jar file)

Example source code:
