Hi Sharma,

The error is pretty clear, it’s a SSL certificate issue.

It doesn’t look like you are “missing” anything, the error suggests that the hostname on the SSL certificate doesn’t match the server name, this would be a server configuration issue? You could try contacting the jython forum to see if it’s a known issue and what the workaround might be.

I haven’t used jython for years, so sorry I can’t be more help than that,

Dave.
