本文實例講述了Java調用WebService接口的方法。分享給大家供大家參考。具體如下：

這里講述有參方法Add，代碼如下：

	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));

	            //設置要調用的方法

	            call.setOperationName(new QName("//www.ythuaji.com.cn/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);

	            //方法的返回值類型

	            call.setReturnType(org.apache.axis.encoding.XMLType.XSD_INT);

	            call.setUseSOAPAction(true);

	            call.setSOAPActionURI("//www.ythuaji.com.cn/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);

	        }

	}
