Clustered enterprise JavaTM in a secure distributed processing system
First Claim
1. A system for communication between processing devices in a cluster, comprising:
- a first processing device, having a first virtual machine executing thereon, a first remote method invocation layer, and a first kernel that includes a first message data structure corresponding to a second virtual machine executing at a second processing device;
a second processing device, having the second virtual machine executing thereon, a second remote method invocation layer, and a second kernel that includes a second message data structure corresponding to the first virtual machine executing at the first processing device; and
wherein a message can be transferred from the first remote method invocation layer to the second remote method invocation layer via the first message data structure on the first processing device, and the second message data structure on the second processing device.

Abstract
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.

10. A method of communication between processing devices in a cluster, comprising the steps of:
-
providing a first processing device, having a first virtual machine executing thereon, a first remote method invocation layer, and a first kernel that includes a first message data structure corresponding to a second virtual machine executing at a second processing device;
providing a second processing device, having the second virtual machine executing thereon, a second remote method invocation layer, and a second kernel that includes a second message data structure corresponding to the first virtual machine executing at the first processing device; and
transferring a message from the first remote method invocation layer to the second remote method invocation layer via the first message data structure on the first processing device, and the second message data structure on the second processing device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A computer readable medium including instructions stored thereon which when executed cause the computer to perform the steps of:
-
providing a first processing device, having a first virtual machine executing thereon, a first remote method invocation layer, and a first kernel that includes a first message data structure corresponding to a second virtual machine executing at a second processing device;
providing a second processing device, having the second virtual machine executing thereon, a second remote method invocation layer, and a second kernel that includes a second message data structure corresponding to the first virtual machine executing at the first processing device; and
transferring a message from the first remote method invocation layer to the second remote method invocation layer via the first message data structure on the first processing device, and the second message data structure on the second processing device.
