I am having problems getting jython extensions to install. Here is an error I get when trying to install active scan ++. I have jython 2.5.3 installed. java.lang.Exception: Failed to open Jython JAR file at burp.p9b.<init>(Unknown Source) at burp.hec.a(Unknown Source) at burp.c5c.a(Unknown Source) at burp.c5c.a(Unknown Source) at burp.ptf.d(Unknown Source) at burp.ptf.a(Unknown Source) at burp.bq.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Thanks

This error happens when you have configured a JYthon file location in your Extender settings, but Burp wasn't able to open the file. Can you reconfigure the location of the JAR file and ensure that Burp is able to open it?

Karthik - the key part of the error message is "Failed to open Jython JAR file". You need to confirm you have the Jython standalone on your system, and that Burp is configured to use the correct path.
