CXF客户端返回NullPointerException

我使用CXF作为我的Web服务后端/客户端存根控件。当客户端调用Web服务，我得到以下错误：CXF客户端返回NullPointerException

java.lang.NullPointerException

    at com.amazonws.AmazonWS.createAmazonWS(AmazonWS.java:49)

线49分以下指令：

AmazonWS client = (AmazonWS) factory.create();

其中涉及以下块之后：

JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); 
factory.getInInterceptors().add(new LoggingInInterceptor()); 
factory.getOutInterceptors().add(new LoggingOutInterceptor()); 
factory.setServiceClass(AmazonWS.class); 
factory.setAddress("http://localhost:9000/helloAmazon");

我做错了什么？似乎我的客户甚至无法访问Web服务。为什么？

谢谢

，你有没有收到任何结果？ –

没关系：当我输入：'http：// localhost：9000/helloAmazon？wsdl'时，我可以拥有我的wsdl – Raphael

CXF的哪个版本？看起来像CXF的一个古老版本，JAXBDataBinding的第559行有任何可以使NPE使用一年的代码。尝试更新版本的CXF。 –

请问您可以发布想要的CXF版本吗？

还要确保你导入所有您需要的CXF XML：

<import resource="classpath:META-INF/cxf/cxf.xml" /> 
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> 
<import resource="classpath:META-INF/cxf/cxf-extension-http.xml" /> 
<import resource="classpath:META-INF/cxf/osgi/cxf-extension-osgi.xml" />

和尝试，如果你在地址在你的网页浏览器中键入使用http://localhost:9000/helloAmazon?wsdl代替http://localhost:9000/helloAmazon
