<property name="serviceInterface" value="com.apress.timesheets.service.UserAccountService"/> </bean> </beans> The serviceUrl property defines the network location of the service we are connecting to. This is composed of the protocol (RMI), the hostname (localhost in my example, but you can site the client and server on different platforms if you change this configuration detail), and the port upon which you are connecting, which must correspond to the registry port specified in Listing 9-3 (both the client and the server will default to port 1099 if none is explicitly specified). The final part of the URL is the name of the service configured with the serviceName property in Listing 9-3. This is arbitrarily selected by the person configuring the service. The serviceInterface property specifies the fully qualified class name of the interface defining the API to the service. The implementation of this interface must be present on the client as well as on the server because it is the template used to create the proxy object that will represent the remote implementation. Listing 9-5 shows an implementation of the client.

This uses a single context configuration file named timesheet-client.xml that configures the single bean of Listing 9-4. This implementation uses the RMI service to obtain a list of the UserAccount objects known to the remote system (the process of serializing a Hibernate entity will force the loading of any lazily loaded properties) and then iterates over the list displaying the usernames of the accounts.

Spring provides its own mechanism for remoting: the HTTP invoker. As this name suggests, this is available purely for the purpose of building web services. Its sole advantages over RMI are that it is marginally simpler to configure and is explicitly intended for use over HTTP. In principle, it is also possible for third-party clients to invoke Spring s mechanism, but in practice, its relative obscurity and its use of the Java serialization mechanism in encoding objects sent over the network makes this a more theoretical than practical feature. Even among Java developers, those who are unfamiliar with Spring are unlikely to have encountered Spring s HTTP invoker. It also requires the client implementation to use Spring libraries although this is a relatively minor issue because the Spring IOC approach makes Spring s own implementations easy to integrate with other frameworks regardless of their architectural philosophies.
