WebService做媒，Delphi与Java牵手

环境：Win7、Delphi7、JDK6、Tomcat6、XFire1.2

 

Web服务端：

Iweather.java

package net.ly.webservice.biz;

public interface Iweather {
 String weather(String s);
 String weather2();
}

 

WeatherImpl.java

package net.ly.webservice.impl;

import net.ly.webservice.biz.Iweather;

public class WeatherImpl implements Iweather {

 public String weather(String s) {  
  return "Hello " + s ;
 }
 

 public String weather2() {  
  return "abcde2";
 }

}

 

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <servlet>
    <servlet-name>XFireServlet</servlet-name>
    <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class>
    <load-on-startup>0</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>XFireServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
  </servlet-mapping>
</web-app>

 

services.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">
 <service>
  <name>Weather</name>
  <namespace>www.weather.com/Weather</namespace>
  <serviceClass>net.ly.webservice.biz.Iweather</serviceClass>
  <implementationClass>net.ly.webservice.impl.WeatherImpl</implementationClass>
 </service>

</beans>

 

Web服务目录结构如图：

 

 部署，启动Tomcat。

 

 

Delphi代码部分：

cmd打开DOS窗口，cd进入 D:\Program Files\Borland\Delphi7\Bin

WSDLImp http://localhost:8686/myWebService/services/Weather?wsdl

 

在当前目录生成Weather.pas

 

新建Delphi项目，保存项目到文件夹javawebservice，把Weather.pas再拷贝到这个文件夹，然后加入到项目中。

 

在Unit1文件引用Weather，

 

unit Unit1;

interface

uses
  Windows,Messages,SysUtils,Variants,Classes,Graphics,Controls,Forms,
  Dialogs,StdCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

uses  Weather;

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
var
   s,s2:string;
begin
      s:=GetWeatherPortType().weather('dai');
      showmessage(s);
      s2:=GetWeatherPortType().weather2;
      showmessage(s2);
end;

end.

 

 Delphi程序运行界面：

 

 

Web应用和Delphi桌面应用结合，对现实项目开发，解决方案更加灵活，能够打出一套漂亮的组合拳。
