This example is the distributed version of example1 of the Simjava package. A simple source and sink example. The source sends 100 messages to the sink and waits for acknowledgements. This example is composed of 3 Java source files:

• Master.java - Creates an instance of Sim_system and binds it in the RMI registry.
• SourceSlave.java - Event generator.
• SinkSlave.java - Event receiver.

To Run:

1. Download and install the Distributed Simjava Software.

2. Make sure your CLASSPATH variable contains the class files for distributed Simjava. For example, on a UNIX system, you could enter the command:
   setenv CLASSPATH <target directory>/distSimjava1.0/classes:<target directory>/distSimjav1.0/examples/example1:$CLASSPATH

   These values must be set for each machine hosting a distributed Simjava component.

3. Start the RMI registry on the machine where the Master program will be run. For example, on a UNIX system,
   rmiregistry &

4. Start the Master program (on the same host as the RMI registry) by executing the command
   java Master registryHost registryPort #Entities
   where
   • registryHost is the name of the machine where the RMI registry has been started
   • registryPort is the port that the RMI registry is listening to
   • #Entities is the number of remote simjava entities, for this example 2.

   Note: the default port for RMI is 1099.

5. Start the SourceSlave program be executing the command
   java SourceSlave registryHost registryPort

6. Start the SinkSlave program be executing the command
   java SinkSlave registryHost registryPort
