Constructor Detail

TransactionServer

public TransactionServer(String[] args,
                         com.sun.jini.start.LifeCycle lifeCycle)

Parameters:

args - Either the command line arguments or the arguments from the ServiceDescriptor. Either way they identify the jini Configuration (you may specify either a file or URL) and optional overrides for that Configuration.

lifeCycle - The life cycle object. This is used if the server is started by the jini ServiceStarter. Otherwise specify a FakeLifeCycle.

Method Detail

main

public static void main(String[] args)

Starts a new TransactionServer. This can be done programmatically by executing

    new TimestampServer(args, new FakeLifeCycle()).run();
 

within a Thread.

Parameters:

args - The name of the Configuration file for the service.

newService

protected AbstractTransactionService newService(Properties properties)

Description copied from class: AbstractServer

This method is responsible for creating the remote service implementation object. This object MUST declare one or more interfaces that extent the Remote interface. The server will use JERI to create a proxy for the remote object and configure and manage the protocol for communications between the client (service proxy) and the remote object (the service implementation).

Note: You have to implement JoinAdmin in order to show up as an administerable service (blue folder) in the jini Service Browser.

Specified by:

newService in class AbstractServer

Parameters:

properties - The contents of the Properties file whose name was given by the propertyFile value in the Configuration identified to main by its command line arguments.
