axis1.4调用.net webservice返回带图片的对象

近期项目中需要用到webservice，接口提供方使用.net编写，返回的是自定义对象，对象中有图片。
接口描述文件如下

我在调用接口过程中碰到的难题是对返回对象的接受，返回对象是.net中定义的，在java中接受就需要进行序列化，序列化的问题搞了好几天没进展，最后实在没招了就还是使用啦
AXIS1.4的 wsdl2java 生成客户端，从生成的代码中找到了序列化返回对象的类，修改后直接引用。
返回对象在java中的定义（通过wsdl2java生成）

}

当时问什么不直接用wsdl2java生成客户端是因为生成的代码在当时还读不懂，没有可控性
所以选择了自己手写客户端，第一次学习使用webservice，有不足地方请大家指正，共同学习，共同前进。

谢谢  在网上找了N久，没有看到一个像样的文章 都是抄过来抄过去的。

中国的程序员真是相当 “拉及”！
