Java Connections determine how many simultaneous requests your servlet can handle. Our servlet runner (Caucho's Resin) exploits Java's multi-threaded nature to allow concurrent instances of a servlet to run without disturbing each other. Note that the number of Java Connections you have doesn't equal the number of simultaneous visitors your website may attract - most client requests take a few milliseconds to complete, so even one Java Connection can serve many site visitors.
