TuscanySCA4-Single Process中运行Composite Application

1. 准备Contributions

??? Contributions是SCA的打包策略，其中可包含：可执行的代码，Composite,或其他的组件(如：Scheme??

??? File，WSDLFile, ZIP，WAR).

??? Contributions可以Export或Imoport XML 命名空间或Java Package，这样可以是相同的命名空间在多个??

??? Contributions之间共享避免了在不同Contributions中有重复命名空间的问题。

??? Export Namespaces:

??? <contribution xmlns="http://www.osoa.org/xmlns/sca/1.0"
????????????? xmlns:tst="http://tuscanyscatours.com/">
????????????? <export.java package="com.tuscanyscatours" />
????????????? <deployable composite="tst:Tours" />
??? </contribution>

??? Import Namespaces:

??? <contribution xmlns="http://www.osoa.org/xmlns/sca/1.0"
????????????? xmlns:client="http://client.scatours/">
????????????? <import.java package="com.tuscanyscatours" />
????????????? <deployable composite="client:Client" />
??? </contribution>

2. Launcher Contributions的代码

??? public class IntroducingLauncher {

????????? public static void main(String[] args) throws Exception {

???????????????? //找到并创建Contributions，此处的第一个参数代表Compostie被部署后的名字，为null意味着：

???????????????? //本节点的执行环境将被部署在该Contributios中的所有Composite联合创建。
?????? ? ? ? ? ? SCANode node = SCANodeFactory.newInstance().createSCANode(null,
?????????????????????????????????????????????????????? locate("introducing-tours"),
?????????????????????????????????????????????????????? locate("introducing-trips"),
?????????????????????????????????????????????????????? locate("introducing-client"));

???????????????? node.start();

???????????????? //得到introducing-client组件中的Runnabel服务
???????????????? Runnable proxy = ((SCAClient)node).getService(Runnable.class,

??????????????????????? "TestClient/Runnable");

?

???????????????? //调用introducing-client组件中的Runnabel服务中格的run方法
???????????????? proxy.run();

???????????????? node.stop();
????????? }
? ? }

??? 注意：Tuscany1.x执行环境中，需要Imports的Contributuions需要放置在Exports的Contributions后面。

3. 运行Launcher

??? 运行上面代码的Main方法。
