org.jboss.invocation.pooled.server
Class PooledInvokerHA

java.lang.Object
  org.jboss.mx.util.JBossNotificationBroadcasterSupport
      org.jboss.system.ServiceMBeanSupport
          org.jboss.invocation.pooled.server.PooledInvoker
              org.jboss.invocation.pooled.server.PooledInvokerHA

All Implemented Interfaces:: InvokerHA, javax.management.MBeanRegistration, javax.management.NotificationBroadcaster, javax.management.NotificationEmitter, org.jboss.invocation.pooled.server.PooledInvokerMBean, Runnable, org.jboss.system.Service, org.jboss.system.ServiceMBean

public final class PooledInvokerHA
extends org.jboss.invocation.pooled.server.PooledInvoker
implements InvokerHA

This invoker pools Threads and client connections to one server socket. The purpose is to avoid a bunch of failings of RMI. 1. Avoid making a client socket connection with every invocation call. This is very expensive. Also on windows if too many clients try to connect at the same time, you get connection refused exceptions. This invoker/proxy combo alleviates this. 2. Avoid creating a thread per invocation. The client/server connection is preserved and attached to the same thread. So we have connection pooling on the server and client side, and thread pooling on the server side. Pool, is an LRU pool, so resources should be cleaned up.
