用的Java調用WebService的

這是一個用Java的調用C＃版的WebService介面的例子：
C＃介面：

<span style="font-size: 11px;">using System;using System.Web;using System.Web.Services;using System.Web.Services.Protocols;using System.Web.Services.Description;[WebService(Namespace = "http://www.tangs.com/")][WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]public class Service : System.Web.Services.WebService{public Service () ...{//如果使用設計的組件，請取消注釋以下行 //InitializeComponent(); } [SoapRpcMethod(Action = "http://www.tangs.com/Add", RequestNamespace = "http://www.tangs.com/T", ResponseNamespace = "http://www.tangs.com/T", Use = SoapBindingUse.Literal)] [WebMethod]public int Add(int a, int b)...{return a + b; } [SoapRpcMethod(Action = "http://www.tangs.com/Hello", RequestNamespace = "http://www.tangs.com/T", ResponseNamespace = "http://www.tangs.com/T", Use = SoapBindingUse.Literal)] [WebMethod]public String HelloWorld()...{return "Hello, world!"; }}...</span>

Java的調用這個web服務中的添加方法和HelloWorld的方法：

1，有參方法：添加

<span style="font-size: 11px;">public static void addTest() {try ...{ Integer i = 1; Integer j = 2;//WebService URL String service_url = "http://localhost:4079/ws/Service.asmx"; Service service = new Service(); Call call = (Call) service.createCall(); call.setTargetEndpointAddress(new java.net.URL(service_url));//設定要調用的方法call.setOperationName(new QName("http://www.tangs.com/T", "Add"));//該方法需要的參數call.addParameter("a", org.apache.axis.encoding.XMLType.XSD_INT, javax.xml.rpc.ParameterMode.IN); call.addParameter("b", org.apache.axis.encoding.XMLType.XSD_INT, javax.xml.rpc.ParameterMode.IN);//方法的傳回值類型call.setReturnType(org.apache.axis.encoding.XMLType.XSD_INT); call.setUseSOAPAction(true); call.setSOAPActionURI("http://www.tangs.com/Add");//調用該方法Integer res = (Integer)call.invoke(new Object[]...{ i, j } ); System.out.println( "Result: " + res.toString()); } catch (Exception e) ...{ System.err.println(e); } }...</span>

運行，結果返回：結果：3

2.無參方法：的HelloWorld

<span style="font-size: 11px;">public static void helloTest() {try ...{ String endpoint = "http://localhost:4079/ws/Service.asmx"; Service service = new Service(); Call call = (Call) service.createCall(); call.setTargetEndpointAddress(new java.net.URL(endpoint)); call.setOperationName(new QName("http://www.tangs.com/T", "HelloWorld")); call.setUseSOAPAction(true); call.setSOAPActionURI("http://www.tangs.com/Hello"); String res = (String)call.invoke(new Object[]...{null } ); System.out.println( "Result: " + res); } catch (Exception e) ...{ System.err.println(e.toString()); } }...</span>

可以看到，調用無參的web服務和有參的基本相同，不過無參調用時，不需要調用呼叫的addParameter方法和setReturnType方法
