public class HelloService {            
    public String sayHello(){  
        return "hello";

    public void updateData(String data){  
        System.out.println(data+" 已更新。");

services.xml配置一：

<?xml version="1.0" encoding="UTF-8"?>  
<service name="HelloService">  
    <description>  
        Web Service例子  
    </description>  
    <parameter name="ServiceClass">  
        com.wm5920.webservice.HelloService  
    </parameter>  
    <messageReceivers>  
        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"  
            class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />  
        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"  
            class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />  
    </messageReceivers>  
</service>

services.xml配置二：

配置1是为具体的操作方法指定消息接收器，配置2是<span style="color: rgb(51,51,51); font-family: Arial; line-height: 26px;">服务级消息接收器。推荐使用配置2</span>

<span style="color: rgb(51,51); font-family: Arial; line-height: 26px;">在部署时，Axis2会自动给操作选择正确的消息接收器，不用像配置1每个操作都要配置</span>

<span style="color: rgb(51,51); font-family: Arial; line-height: 26px;">
</span>
