java调用WSDL出问题
java调用

import javax.xml.namespace.QName;
import org.apache.axis2.addressing.EndpointReference;  
import org.apache.axis2.client.Options;  
import org.apache.axis2.rpc.client.RPCServiceClient; 
public class CallWsdl {

 public static void main(String[] args) {  
	  
	        try {  
   
	        //  使用RPC方式调用WebService          
	            RPCServiceClient serviceClient = new RPCServiceClient();  
	            Options options = serviceClient.getOptions();  
	            //  指定调用WebService的URL  
	            EndpointReference targetEPR = new EndpointReference(  
	                    "http://localhost:8080/tiger/wstiger/TraderService?wsdl");  
	            options.setTo(targetEPR);  
	            //  指定sayHelloToPerson方法的参数值  
	            Object[] opAddEntryArgs = new Object[] {"2c90817157ffd27f0157ffd9943a0171"};  
	            //  指定sayHelloToPerson方法返回值的数据类型的Class对象  
	            Class[] classes = new Class[] {String.class};  
	            //  指定要调用的sayHelloToPerson方法及WSDL文件的命名空间  
	            QName opAddEntry = new QName("http://service.ws.tiger.com", "getTraderInfo");  
	            //  调用sayHelloToPerson方法并输出该方法的返回值  
	            System.out.println(serviceClient.invokeBlocking(opAddEntry, opAddEntryArgs, classes)[0]);  
	        } catch (Exception e) {  
	            e.printStackTrace();  
	        }  
	  
	    }  
	    
}

服务器端

@WebService(targetNamespace="http://service.ws.tiger.com")
public interface TraderService {
	
	public String getTraderInfo(@WebParam(name="usercode",targetNamespace = "http://service.ws.tiger.com") String usercode) throws Exception;
	
}

================================================
报错

服务器端被其他程序调用是正常的，服务器端应该没问题。

感谢大家！

改用接口的方式调用，RPCServiceClient有一定局限性，就目前的信息是客户端调用时只传递了参数值没有名称系统默认“arg0”，但是服务器要求参数名称为usercode，要么弃用arg0，要么服务端弃用@WebParam

感谢！ 我换了一个方式，使用SOAP调用的。

用这个方式调用成功了

URL wsUrl = new URL("http://localhost:8080/tiger/wstiger/TraderService?wsdl");
	            
	            HttpURLConnection conn = (HttpURLConnection) wsUrl.openConnection();
	            
	            conn.setDoInput(true);
	            conn.setDoOutput(true);
	            conn.setRequestMethod("POST");
	            conn.setRequestProperty("Content-Type", "text/xml;charset=UTF-8");
	            
	            OutputStream os = conn.getOutputStream();
	            
	            //请求体
	            String soap = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\"  xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">" + 
	                          "<soapenv:Body> <getTraderInfo xmlns=\"http://service.ws.tiger.com\"><usercode>2c90817157ffd27f0157ffd9943a0171</usercode>  </getTraderInfo> </soapenv:Body> </soapenv:Envelope>";
	            
	            os.write(soap.getBytes());
	            
	            InputStream is = conn.getInputStream();
	            
	            byte[] b = new byte[1024];
	            int len = 0;
	            String s = "";
	            while((len = is.read(b)) != -1){
	                String ss = new String(b,0,len,"UTF-8");
	                s += ss;
	            }
	            System.out.println(s);
	            
	            is.close();
	            os.close();
	            conn.disconnect();
