[maemo-developers] [maemo-developers] JamVM network prob

[From: Philippe Laporte]

Hi,
   I've been running the GST client on the 770 with various VMs (JamVM,
CACAO, SableVM, Mika) for a while and have not had problems with TCP/IP.
Never tried UDP though.

Make sure you setup a WLAN connection or other *before* running the
program.


Best Regards,
