[stunnel-users] Stunnel & Java SSL

Sat Oct 30 09:34:29 CEST 2004

Managed to sort this issue out by upgrading my JVM to 1.5.0 and adding the
certificated in under the Java control panel.
Ran into another problem afterwards with my application generating an
UNKNOWN PROTOCOL error on the 3rd TCP session after successfully accepting
the first two... very strange.  I think I'm going to have to give up on
the idea of using Java's or IE's SSL system and use Stunnel as a client
too.   Found a great GUI for Stunnel on Mac OS X called SSL Enabler, shame
theres not one as nice for Windows!
