Hmm, so I decided that I should just try and use Sockets to get my JSP
to talk to the Mythbackend.
Whenever I try and connect to the server, my backend gets stuck in
what seems to be an infinite loop of waiting for a thread as shown
from the log...
2005-02-23 23:06:33 waiting for a thread..
2005-02-23 23:06:33 waiting for a thread..
2005-02-23 23:06:33 waiting for a thread..
2005-02-23 23:06:33 waiting for a thread..
2005-02-23 23:06:33 waiting for a thread..
2005-02-23 23:06:33 waiting for a thread..
... I have been using mythweb as an example of how to communicate to
the server, but it doesn't seem to work too well.
I am using 0.16 but have been using the code from 0.17 to see how this
stuff is intepreted. I hope the general rules didn't change too much.
I have attached the Java code incase anyone wanted to take a look, but
any other pointers would be great.
Cheers,
Whytey
