Question

java.lang.NoClassDefFoundError: javax/xml/ws/soap/MTOM

这究竟是什么问题？麻烦帮看下，是不是少了什么？
public final class Client{

private Client(){

}
public static void main(String args[]) throws Exception{
// START SNIPPET: client

JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.getInInterceptors().add(new LoggingInInterceptor());
factory.getOutInterceptors().add(new LoggingOutInterceptor());
factory.setServiceClass(HelloWorld.class);
String endpointAddress = "http://localhost:8080/cxf/HelloWord";
factory.setAddress( endpointAddress );
HelloWorld client = (HelloWorld) factory.create();// 出错在这里。

//String reply = client.sayHi("HI");
//System.out.println("Server said: " + reply);
System.out.println("Server said: "+"你好吗？" );
System.exit(0);

}
}

Answer 1

缺少相关Jar包,javax.xml.soap在JDK中缺省是不存在的

Answer 2

xml配置的问题，或者是你的类的位置没有放进指定的包

Answer 3

没有找到类JaxWsServiceFactoryBean可能出错了

Answer 4

HelloWorld 在哪里？
