用的Java呼叫WebService的

這是一個用Java的呼叫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 () ...{
//如果使用设计的组件，请取消注释以下行 
//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的呼叫這個web服務中的新增方法和HelloWorld的方法：

1，有參方法：新增

<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));
//设置要调用的方法
call.setOperationName(new QName("http://www.tangs.com/T", "Add"));
//该方法需要的参数
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);
//方法的返回值类型
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_INT);
 call.setUseSOAPAction(true);
 call.setSOAPActionURI("http://www.tangs.com/Add");
//调用该方法
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
