HowTo: Jython smtplib: java.net.SocketException: Network is unreachable: connect --- workaround

************ workaround ----------------------
tell Java to prefer the IPv4 stack by either

- command line parameter -Djava.net.preferIPv4Stack=true

- or using this in the script before touching smtplib features:
import java.lang.System as JS
JS.setProperty("java.net.preferIPv4Stack", "true")

---------------------------------------- thanks for finding

Hy,

I need to send an email after execution.

So, I use smtplib. And it's working from a python console.

When I implemente the code in a sikuli script, and execute with runsikulix.cmd -r <script> , I've the following message :

[error] socket.error ( (-1, 'Unmapped exception: java.net.SocketException: Network is unreachable: connect') )
