CUBA Platform. Developer's Manual
4.4.1. Services

In order to call the service, the corresponding proxy object should be created in the client block of the application. Declare the service name and interface in the parameters of the proxy object factory to achieve this. For the Web Client block, it is WebRemoteProxyBeanCreator, for Web Portal – PortalRemoteProxyBeanCreator , for Desktop Client – RemoteProxyBeanCreator .

The proxy object factory is configured in spring.xml of the corresponding client block.

For example, to call the sales_OrderService service from the web client in the sales application, it is necessary to add the following code into the web-spring.xml file of the web module:

<bean id="sales_proxyCreator" class="com.haulmont.cuba.web.sys.remoting.WebRemoteProxyBeanCreator">
    <property name="clusterInvocationSupport" ref="cuba_clusterInvocationSupport"/>
    <property name="remoteServices">
        <map>
            <entry key="sales_OrderService" value="com.sample.sales.core.OrderService"/>
        </map>
    </property>
</bean>

All imported services are declared in a single remoteServices property in the map/entry elements.

From the application code perspective, the service’s proxy object at the client level is a standard Spring bean and can be obtained either by injection or through AppBeans class. For example:

@Inject
protected OrderService orderService;
...
orderService.calculateTotals(order);
