DELPHI XE6调用JAVA WEBSERVICE

DELPHI客户端访问WEBSERVICE方法

1. 首先取得java-webservice服务器端地址。我的是：http://localhost:8080/mywebservice/services/mywebservice?wsdl

2. 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：

unit mywebservice;

uses InvokeRegistry, SOAPHTTPClient, Types, XSBuiltIns;

function add(const a: Integer; const b: Integer): Integer; stdcall; 
function sayHello(const name: WideString): WideString; stdcall; 
end; 

function GetmywebservicePortType(UseWSDL: Boolean=System.False; Addr: string=''; HTTPRIO: THTTPRIO = nil): mywebservicePortType; 


implementation 

function GetmywebservicePortType(UseWSDL: Boolean; Addr: string; HTTPRIO: THTTPRIO): mywebservicePortType; 
const 
defWSDL = 'http://localhost:8080/mywebservice/services/mywebservice?wsdl'; 
defURL = 'http://localhost:8080/mywebservice/services/mywebservice'; 
defSvc = 'mywebservice'; 
defPrt = 'mywebserviceHttpPort'; 
var 
RIO: THTTPRIO; 
begin 
Result := nil; 
if (Addr = '') then 
begin 
if UseWSDL then 
Addr := defWSDL 
else 
Addr := defURL; 
end; 
if HTTPRIO = nil then 
RIO := THTTPRIO.Create(nil) 
else 
RIO := HTTPRIO; 
try 
Result := (RIO as mywebservicePortType); 
if UseWSDL then 
begin 
RIO.WSDLLocation := Addr; 
RIO.Service := defSvc; 
RIO.Port := defPrt; 
end else 
RIO.URL := Addr; 
finally 
if (Result = nil) and (HTTPRIO = nil) then 
RIO.Free; 
end; 
end; 


initialization 
InvRegistry.RegisterInterface(TypeInfo(mywebservicePortType), 'http://server', 'UTF-8'); 
InvRegistry.RegisterDefaultSOAPAction(TypeInfo(mywebservicePortType), ''); 
InvRegistry.RegisterInvokeOptions(TypeInfo(mywebservicePortType), ioDocument); 
InvRegistry.RegisterExternalParamName(TypeInfo(mywebservicePortType), 'add', 'out_', 'out'); 
InvRegistry.RegisterExternalParamName(TypeInfo(mywebservicePortType), 'sayHello', 'out_', 'out'); 

end.

3.

新建一个form窗体，拖入一个Button和一个edit控件。 
在窗体的uses部分加入InvokeRegistry, Rio, SOAPHTTPClient, mywebservice。 
为Button添加click事件。 
Java代码 收藏代码
procedure TForm1.Button1Click(Sender: TObject); 
var 
server:mywebservicePortType;//此处为delphi生成的java-webservice的方法名。 
aa:string; 
begin 
server:=GetmywebservicePortType(true,'',nil);//delphi生成的方法 
showmessage(server.sayHello(Edit1.Text));//调用java-webservice的sayHello()方法。 
end;

到此，delphi调用java的webservice服务器端程序示例已经完成。
