java - 调用网络服务

Question

我编写了一个似乎运行良好的 Web 服务 - 我可以使用 Netbeans 界面调用它。我还编写了另一个应用程序，可以在 Netbeans 编译器 (6.7.1) 中运行时调用它。但是，当我将它部署在 Tomcat 下的托管服务器上时 - 一旦访问 Web 服务，就会抛出以下错误页面:

Answer 1

Exception Details: java.lang.NoClassDefFoundError javax/xml/rpc/ServiceException

这意味着您缺少提供 javax.xml.rpc.ServiceException 的 jar。将其添加到您的项目并重新部署，它应该会消失。
