Class ApplicationStarter

java.lang.Object
  jgroup.arm.ApplicationStarter

public final class ApplicationStarter
extends java.lang.Object

The application starter class is wrapper for starting a server replica in a separate child JVM process, and sets up a pipe between the parent and child process. This allows the parent process (the ExecDaemon) to control the child process (the server replica), for example the ExecDaemon may wish to kill the replica. Note that, unless the server replica is using the Replication service, or if the server has specific shutdown needs, the server should consider adding a shutdown hook so as to ensure that the replica releases any held resources when being killed. This class can also be used to start a server through its constructor without having to recompile it. That is, this wrapper will take care of obtaining the group manager for the server. This means that the server can be made into a replicated server without changing it. This assumes that the server does not need to use any of the services or listeners provided through the Jgroup group manager. For simple replication this should be no problem.
