SCA产品部署

内嵌容器与Servlet容器：内嵌容器每个域都需要它自己的专用IP端口,而Servlet容器可以在单个实例中运行多个域。

部署步骤：

1. 创建符合WAR要求的目录结构：

??? 参考附件ProductionDeployment.rar

2. 创建一个sca-contribution.xml文件定义使用的域和组合：

??? <contribution xmlns="http://www.osoa.org/xmlns/sca/1.0"
????????????? xmlns:hw="http://opensoa.book.chapter441"> <!--定义命名空间-->

???????? <!--指明要部署的组合-->
???????? <deployable composite="hw:ProblemManagementComposite"/>
??? </contribution>

3. 创建一个web.xml文件，将Tuscany配置为一个servlet filter拦截到SCA域的请求：

??? <web-app>

??????? <display-name>OpenSOA Chapter 3</display-name>

??????? <filter>
???????????? <filter-name>tuscany</filter-name>
???????????? <filter-class>org.apache.tuscany.sca.host.webapp.TuscanyServletFilter</filter-class>
??????? </filter>
??????? <filter-mapping>
???????????? <filter-name>tuscany</filter-name>
???????????? <url-pattern>/*</url-pattern>
??????? </filter-mapping>

??????? <welcome-file-list id="WelcomeFileList">
???????????? <welcome-file>hello.html</welcome-file>
??????? </welcome-file-list>
??? </web-app>

4. 创建一个Ant任务来装配WAR文件

??? <target name="compile" description="Compiles Java code AND creates WAR file for deployment

???????? to Tomcat...">
??? ??? <mkdir dir="target/classes" />
??? ??? <javac destdir="target/classes" debug="on" source="1.5" target="1.5">
??? ??? ??? <src path="src\main\java" />
??? ??? ??? <classpath>
??? ??? ??? ??? <fileset dir="${tuscany.lib}">
??? ??? ??? ??? ??? <include name="*.jar"/>
??? ??? ??? ??? </fileset>
??? ??? ??? ??? <fileset dir="${general.lib}">
??? ??? ??? ??? ??? <include name="*.jar"/>
??? ??? ??? ??? </fileset>
??? ??? ??? </classpath>
??? ??? </javac>

??? ??? <copy todir="target/classes">
??? ??? ??? <fileset dir="src\main\resources" />
??? ??? </copy>

??? ??? <war destfile="target/opensoa-chapter4.war" webxml="src/main/webapp/WEB-INF/web.xml">
??? ??? ??? <fileset dir="src/main/webapp"/>
??? ??? ??? <lib refid="tuscany.jars"/>
??? ??? ??? <lib refid="3rdparty.jars"/>
??? ??? ??? <classes dir="target/classes"/>
??? ??? </war>
??? </target>

5. 不同域之间的交互方式

??? 分以引用的方式使用组合和通过远程绑定使用Web服务。下面以使用Web服务为例：

??? <composite? xmlns="http://www.osoa.org/xmlns/sca/1.0"
??????????? targetNamespace="http://opensoa.book.chapter441"
??????????? xmlns:hw="http://opensoa.book.chapter441"
??????????? name="IssueManagementComposite">

??????????? <service? name="SystemErrorService"
????????????????? promote="SystemErrorComponent">
???????????????? <binding.ws uri="http://localhost:8085/SystemErrorService" />
??????????? </service>

??????????? <component name="SystemErrorComponent">
??????????????? <implementation.java />
??????????? </component>
??
??????????? <!-- Use this when running in a distributed capacity -->
??????????? <reference name="ProblemTicket"
???????????????????? promote="SystemErrorComponent/problemTicket">
???????????????????? <binding.ws uri="http://localhost:8080/opensoa-chapter4/ProblemTicketService"/>
??????????? </reference>??
??? </composite>
