Spring、Apache CXF 和嵌入式 Jetty

Question

我正在尝试使用 Apache CXF、Spring 和嵌入式 Jetty 服务器创建一个支持 Web 服务的服务器。当我运行我的项目时，服务器似乎正确初始化，但是当我导航到 http://localhost:8080/SomeService 期望看到服务 WSDL，但我得到以下异常：

SEVERE: /SomeService
java.lang.NullPointerException

有什么想法吗？

这是 Java main()

public static void main(String[] args) throws Exception {                    
    new ClassPathXmlApplicationContext(new String[] {"beans-jetty.xml"});
}

beans-jetty.xml

<jaxws:endpoint
        id="someService"
        implementor="com.awebster.gitta.services.SomeServiceImpl"
        address="${server.address}" />

我应该提到我正在使用 Maven one-jar 插件，尽管我怀疑这对这个问题有任何影响。

非常感谢！
