To start the PJODeRMIServer, simply execute the PJODeRMIServer class using no arguments. It will be bound as "PJODe" on port 1099:
java com.linxpda.PJODe.server.PJODeRMIServer
Other than launching a PJODeRMIServer, the API for this class is executed through remote instances of PJODe (see {@link com.linxpda.PJODe.PJODe#getRemoteInstance(String, String) PJODe.getRemoteInstance} for more details on referencing remote PJODe databases) and need not be accessed directly by your code.
