org.apache.axis2.AxisFault:ServiceclassXXXXXmusthavepublicasaccessModifier解决方案

使用Axis2工具生成客户端调用辅助类后，编写客户端调用代码运行时报错，完整错误信息如下：

log4j:WARN No appenders could be found for logger (org.apache.axiom.locator.DefaultOMMetaFactoryLocator).
log4j:WARN Please initialize the log4j system properly.
org.apache.axis2.AxisFault: Service class com.csdn.ws.axis2.recipe01.HelloWorld must have public as access Modifier

    at com.csdn.ws.axis2.recipe01.client.Client.main(Client.java:15)

乍一看错误信息好像是说web服务接口和实现类必须定义为public，检查代码发现就是public，真正的原因是在services.xml中描述WebService时

"ServiceClass">
        com.csdn.ws.axis2.recipe01.HelloWorldImpl

ServiceClass属性应该指定Web服务实现类，而不是接口。
