39  * <p>
40  * The RSHJVMProcess class is able to start any class, of the ProActive library,
41  * using rsh protocol. The difference between this class and RSHProcess class is that the target process
42  * for this class is automatically a JVMProcess, whereas for the RSHProcess, the target process has to be defined
43  * and can be any command and any process.
44  * </p><p>
45  * For instance:
46  * </p><pre>
47  * .......
48  * RSHProcess rsh = new RSHJVMProcess(new StandardOutputMessageLogger());
49  * rsh.setHostname("machine_name");
50  * rsh.startProcess();
51  * .....
52  * </pre>
53  * <p>
54  * This piece of code creates a new RSHJVMProcess. It allows to log on a remote machine with the rsh protocol and then,
55  * on this machine to create a Java Virtual Machine, by launching a ProActive java class.
56  * </p>
