【JAVA开发】 关于WebService服务端

[IT_dream]

最近在做一个webservice的通讯服务端，拿到的wsdl服务demo，正常生成，发布没有问题，现在想调整下，整改成自己的程序。修改了原有WSDL文件中的targetNamespace xmlns:tns 之后可以生成服务端代码，程序启动没错。但访问会提示

各位大神请指点

[exception92]

org.apache.axis.encoding.ser.BeanSerializer cannot be cast to org.apache.axis.encoding.Serializer -》 类转换错误吧？ org.apache.axis.encoding.ser.BeanSerializer 不能转成 org.apache.axis.encoding.Serializer ，这个和webService没关系吧，让版主把帖子移动Java板块问问。

重新试了一把，可以了，但是不明白为什么。图一中标红的改成了下图标红的样子，重新生成了一下。就正常了，不晓得什么原因，有知道吗？
