我通过在 eclipse juno 中使用 Axis 2 使用自下而上的方法创建了两个数字 Web 服务的简单相加。Web 服务正常工作并通过 soa 客户端 mozilla 扩展进行了正确测试，但 tomcat 中存在错误。请查看以下错误
计算器服务无效，导致

最佳答案
Tomcat 只是一个 servlet 容器和 AFAIK，它默认不支持任何类型的 web 服务。
您必须在 WEB-INF/lib 中包含所需的库，或者将其添加到 tomcat lib 文件夹中并使用它。
您将收到 ClassNotFoundException，因为在类路径中找不到 javax/ws/rs/Produces。
将 REST 实现(例如:Jersey)部署到服务器库并重新启动服务器。
