java调用.net webservice的完整实例

Java客户端调用Web Service的一般有以下三种方式：
生成的stub、proxy(动态代理)以及dispatch(动态调用接口)。dispatch又分为payload和message两种方式。
这个实例仅就dispatch的message方式进行介绍。

C#代码

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Services;

using System.Web.Services.Protocols;

using System.Web.Services.Description;



namespace WebService1

{

/// <summary>

/// Service1 的摘要说明

/// </summary>

[WebService(Namespace = "http://tempuri.org/")]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

[System.ComponentModel.ToolboxItem(false)]

// 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。

// [System.Web.Script.Services.ScriptService]

[SoapDocumentService(RoutingStyle = SoapServiceRoutingStyle.RequestElement)] 

public class Service1 : System.Web.Services.WebService

{





[WebMethod]

public string HelloWorld(string strHost)

{

return "Hello World, "+strHost;

}

}

}

MessageFactory factory = ((SOAPBinding)bp.getBinding()).getMessageFactory();



SOAPMessage request = factory.createMessage();

SOAPBody body = request.getSOAPBody();

QName payloadName = new QName(targetNamespace, OPER_NAME); 

SOAPBodyElement payload = body.addBodyElement(payloadName);



SOAPElement message = payload.addChildElement(INPUT_NMAE);

message.addTextNode("xyz");

SOAPMessage reply = null;



try

{

reply = dispatch.invoke(request);

}

catch (WebServiceException wse)

{

wse.printStackTrace();

}

SOAPBody soapBody = reply.getSOAPBody();

SOAPBodyElement nextSoapBodyElement = (SOAPBodyElement)soapBody.getChildElements().next (); 

SOAPElement soapElement = (SOAPElement)nextSoapBodyElement.getChildElements().next();



System.out.println("获取回应信息为：" + soapElement.getValue()); 

}

}

输出：

Hello World, xyz
