classserver.jar refusing connection
Folks; I spoke too soon. About 10 seconds after starting jspace.shl
(see below) I get the following error -- apparently caused by classerver.jar
refusing a connection attempt from phoenix.jar. I've tried to lift all
security restrictions and I think I've got everyone using port 4160. As
you can see, classserver.jar is indeed running. I also tried replacing
SYSTEM_PORT with 4160 in the phoenix.config file, below: same error. How
can I get classserver.jar to tell me why it refused the connection?
Regards,
-Tim

Re: classserver.jar refusing connection
Posted by Niclas Hedhman <ni...@hedhman.org>.
1. Try to connect with a command line tool (curl, wget,...). If that
doesn't work, then all stuff on client side can be ignore for now.
2. Connection Refused means that the class-server will not even see an
attempted connection. It is refused at OS level. I would guess that there
is a firewall blocking port 4160, OR that the class-server has not bound
the listener to the interface you are trying to connect on. You should be
able to use (on Linux) "iptables --list" to verify firewall rules (might
be overwhelmingly complex) and "netstat -tulpn" to check what/how is bound
to 4160 port.
