A clustered enterprise distributed processing system. The distributed processing system includes a first and a second computer coupled to a communication medium. The first computer includes a virtual machine (JVM) and kernel software layer for transferring messages, including a remote virtual machine (RJVM). The second computer includes a JVM and a kernel software layer having a RJVM. Messages are passed from a RJVM to the JVM in one computer to the JVM and RJVM in the second computer. Messages may be forwarded through an intermediate server or rerouted after a network reconfiguration. Each computer includes a smart stub having a replica handler, including a load balancing software component and a failover software component. Each computer includes a duplicated service naming tree for storing a pool of smart stubs at a node.
