OrderServiceClient

public class OrderServiceClient extends Object
Demo client class for remote OrderServices, to be invoked as standalone program from the command line, e.g. via "client.bat" or "run.xml".

You need to specify an order ID and optionally a number of calls, e.g. for order ID 1000: 'client 1000' for a single call per service or 'client 1000 10' for 10 calls each".

Reads in the application context from "clientContext.xml", calling all OrderService proxies defined in it. See that file for details.
