互操作性是Web Service的真正优势,虽然关于WS标准有很多,但不同厂家都是自己的实现,不同实现之间的互操作性因此很差,于是有了WS-I组织成立来治理这种差异,并提供统一的互操作性规范,到目前为止,这些工作仍在进行中,不过成果早已经有了:WS-I Attachment Profile 1.0 并且也已经在Sun提供的WS设施上有了体现,通过使用wscompile 工具中的选项 -f wsi 即可生成兼容WS-I规范的Java制品.
文件清单:
SEI接口类IImage.java,实现SEI接口的类IIMageImpl.java,描述文件信息的值类型类FileInfo.java,Web应用部署描述文件web.XML,WS发布配置文件jaxrpc-ri.xml,WS编译配置文件config-interface.xml,构建客户端桩的config-wsdl.xml,构建文件builder.xml
客户端测试类:Form1.cs.
本例是从WSDL开始的,因此我们要有一个WSDL文件.第一步就是得到这个文件.
(一) 得到WSDL文件.
为达到互操作要求,这个文件的描述必须是文档样式的绑定,文字格式的编码.为得到此文件,首先介绍构建文件builder.xml:
