关于JAVA调用axis客户端爆出org.apache.axis2.AxisFault: Namespace URI may not be nul问题

求教。正在写一个webservice服务，但是，客户端始终提示URI may not be null
下面是我的service.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<service name="ServiceOne">
    
    <parameter name="ServiceObjectSupplier">
        org.apache.axis2.extensions.spring.receivers.SpringAppContextAwareObjectSupplier
    </parameter>

    <parameter name="SpringBeanName">outSideLogin</parameter>

    <operation name="Test">
        <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
    </operation>
</service>

客户端的方法

public static void main(String[] args) throws AxisFault{
RPCServiceClient serviceClient=new RPCServiceClient();
Options options=serviceClient.getOptions();
EndpointReference targetEPR=new EndpointReference("http://localhost:8080/SmartOne/services/ServiceOne");
options.setTo(targetEPR);
Object[] requestParam = new Object[] {"测试"};
Class[] responseParam = new Class[] {String.class};
QName requestMethod = new QName("http://impl.service.admin.smartone.dcits.com","Test");
try{
serviceClient.invokeBlocking(requestMethod, requestParam, responseParam);
}catch(Exception e){
e.printStackTrace();
}
}

其中，这个http://impl.service.admin.smartone.dcits.com是和WDSL文档中的
targetNamespace="http://impl.service.admin.smartone.dcits.com"命名空间一致的。但是，还是报错。
--------------------编程问答-------------------- 我也遇到这个问题了我还遇到那个不能invoke --------------------编程问答-------------------- 求解决方法，楼主解决没？ --------------------编程问答-------------------- LZ你这个应Spring + axis2的配置吧,把
<operation name="Test">
        <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
</operation>

改成

<messageReceivers>
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"
        class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</messageReceivers>
<parameter name="ServiceClass">具体类(outSideLogin类)</parameter>

Test方法不需要写在service.xml上,在QName 写就可以了

补充：Java ,  Web 开发
