}

这个代码示例是一个 Java 接口，而不仅仅是一个 Java 类。 @WebService 注释存在于此 Java 接口中。 必须了解本示例与生成的 @WebServiceClient 类 (com.myaccount.account.AccountWSDLService) 不同，此类不是接口且不为 SCA 应用程序所需。

package com.myaccount.account;
import org.osoa.sca.annotations.Service;
@Service(AccountService.class) 
public class AccountServiceImpl implements AccountService
    public float computeAccountAverage( Account account, int days) {

        // Write your business logic here.  Account is a 
        // generated JAXB type and so use the JAXB programming model. 
        // For example, object instantation is performed using  
        // the ObjectFactory.createAccount()) method. 
    }
}

在完成此步骤后，您就完成了组件实现。 此组件实现不仅是 Java 接口的 Java 实现，而且 @Service 注释还表明这是一个 SCA 服务接口的 Java 组件实现。 实现类本身并不需要所有 JAX-WS 或 JAXB 注释。 运行时环境会从实现所引用的生成类中装入相应的注释。
