SCA组件类型配置

    使用该方式可以替换SCA中的Java注解方式。一般情况下，可用组件类型文件来表明属性，而用注解来标示出引用和

服务。创建默认组件类型文件命名习惯：

    <componetn-implementation-class>.componentType

    例如:ProblemTicketComponentImplNA.componentType:

    <componentType
            xmlns="http://www.osoa.org/xmlns/sca/1.0"
            xmlns:xsd="http://www.w3.org/2001/XMLSchema">

            <service name="ProblemTicketComponent">
            <interface.java
                     interface="opensoa.book.chapter4_1.ProblemTicketComponent" />
            </service>
            <reference name="createTicket">
                     <interface.java
                            interface="opensoa.book.chapter4_1.CreateTicketComponent" />
            </reference>

            <property name="username" type="xsd:string" />
            <property name="password" type="xsd:string" />
     </componentType>
