我在 Eclipse 中创建了带有壁垒 ws 安全性的 axs 2 Web 服务（这是我遵循的 教程 TUTORIAL PAGE - 18-21

我通过添加此代码和参与 RAMPART MODULE 在 service.xml 中应用了该策略

<wsp:Policy wsu:Id="UTOverTransport"
    xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"
    xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy">
    <wsp:ExactlyOne>
        <wsp:All>
            <sp:SignedSupportingTokens
                xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">
                <wsp:Policy>
                    <sp:UsernameToken
                        sp:IncludeToken="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy/IncludeToken/AlwaysToRecipient" />
                </wsp:Policy>
            </sp:SignedSupportingTokens>
            <ramp:RampartConfig xmlns:ramp="http://ws.apache.org/rampart/policy">
                <ramp:passwordCallbackClass>axis2wstest.PWCBHandler</ramp:passwordCallbackClass>
            </ramp:RampartConfig>

        </wsp:All>
    </wsp:ExactlyOne>
</wsp:Policy>

然后我创建 Web 服务客户端 - 这是代码

public static void main(String[] args) throws RemoteException {
          ConfigurationContext ctx;
          ctx = ConfigurationContextFactory.createConfigurationContextFromFileSystem("C:/Users/Tanya/workspace/testlnclient/WebContent/WEB-INF", null);
        TestlnStub stub = new TestlnStub(ctx);

        Testws cl = new Testws();
        cl.setX(5);
        ServiceClient client =  stub._getServiceClient(); 
        client.engageModule("rampart");    
        //client.addHeader(omSecurityElement);
        org.apache.axis2.client.Options o = client.getOptions();
        o.setPassword("pass");
        o.setUserName("test");
        TestwsResponse resp = stub.testws(cl);

        System.out.println("Response" + resp.get_return());


        // TODO Auto-generated method stub

    }

}

但它给了我一个例外

exception in thread "main" org.apache.axis2.AxisFault: java.lang.NullPointerException
    at org.apache.axis2.util.Utils.getInboundFaultFromMessageContext(Utils.java:531)
    at org.apache.axis2.description.OutInAxisOperationClient.handleResponse(OutInAxisOperation.java:375)

堆栈跟踪中的存在Utils.getInboundFaultFromMessageContext表明它NullPointerException实际上来自服务而不是由客户端抛出。检查服务器日志以查看NullPointerException发生的位置。
