Web services javax.xml.ws.soap.SOAPFaultException:NPE位于org.apache.axis2.jaxws.marshaller.impl.alt.MethodMarshallerUtils.createSystemException（1353）

我已经使用wsimport命令使用wsdl（通过IBM的JDK1.6）生成了代码。我还使用IBMRAD作为开发工具，WAS8.5.5作为应用服务器

通过一个简单的客户端程序，我可以调用Web服务。然而，当我与我的项目（web应用程序）集成时，我得到了一个javax.xml.ws.soap.SOAPFaultException:java.lang.NullPointerException。在做了一些谷歌搜索并阅读了有关stackoverflow这个问题的之后，有人建议我删除axis2库，因为可能存在冲突。所以我这么做只是为了看看它是否会工作（同时它会破坏其他东西），但没有运气。任何帮助都将不胜感激。谢谢
