Have you tried the Tribes Cluster configuration without using NIOConnector ?
System properties:
org.apache.tomcat.util. net.NioSelectorShared
If true, use a shared selector for servlet write/read. If
not specified, the default value of true will be used.
http://www.mbaworld.com/docs/config/systemprops.html
configure sender for blocking:
http://www.mbaworld.com/docs/config/cluster-sender.html
configure receiver for blocking:
http://www.mbaworld.com/docs/config/cluster-receiver.html
were you able to ping Filip Hanik for details on using NIOConnector in Tribes
?
