Hi Malaka Thanks for your message. We don't recommend trying to run Python extensions in this way. The preferred way is to launch Burp as usual, configure Burp with the location of the Jython standalone JAR: https://portswigger.net/burp/help/extender.html#options_pythonenv and then load the extension via the Burp UI: https://portswigger.net/burp/help/extender.html#loading Please let us know if you need any further assistance.
