Server Process 
Definition
The server processes of the J2EE Engine actually execute the J2EE application. Each server process is multi-threaded, and can therefore process a large number of requests simultaneously. J2EE Dispatcher assigns requests to the server processes.

· Communication handler (see J2EE Dispatcher)
· Session level services (see J2EE Dispatcher)
· Application-level services or the actual application program.
A server process is constructed in the J2EE cluster as shown in the following graphic:
