delphi7调用java服务器端webservice示例
首先取得java-webservice服务器端地址。我的是：http://localhost:8080/mywebservice/services/mywebservice?wsdl
然后打开delphi7，file-new-other:选择WebService选项卡,在选择WSDLImporter
,在弹出的界面中输入java-webservice地址。点击Next-finish.会生成一个.pas的webservice文件，
生成的代码如下：
// ************************************************************************ //// The types declared in this file were generated from data read from the// WSDL File described below:// WSDL : http://localhost:8080/mywebservice/services/mywebservice?wsdl// Encoding : UTF-8// Version : 1.0// (2011-7-21 10:17:02 - 1.33.2.5)// ************************************************************************ //unit mywebservice;interfaceuses InvokeRegistry, SOAPHTTPClient, Types, XSBuiltIns;type // ************************************************************************ // // The following types, referred to in the WSDL document are not being represented // in this file.
