支持组件模型CCM的开源中间件-mico

/*
 * This file is part of the load-balancing example
 *
 * In this example, the client obtains the reference to a printer server
 * object and then asks the latter to print a message.  If the naming service
 * from where the client obtains the reference does load-balancing, the
 * client might obtain the reference to a potentially different server object
 * each time it does nc->resolve() or nc->resolve_str().
