怎么用Java通过wsdl地址调用WebService求代码

我觉得这种方法比较适合那些高手，他们能直接看懂XML格式的WSDL文件，我自己是看不懂的，尤其我不是专门搞这行的，即使一段时间看懂，后来也就忘记了。直接调用模式如下：
import java.util.Date;
import java.text.DateFormat;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
import java.lang.Integer;
import javax.xml.rpc.ParameterMode;

public class caClient {

public static void main(String[] args) {

try {
String endpoint = "http://localhost:8080/ca3/services/caSynrochnized?wsdl";
//直接引用远程的wsdl文件
//以下都是套路
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(endpoint);
call.setOperationName("addUser");//WSDL里面描述的接口名称
call.addParameter("userName", org.apache.axis.encoding.XMLType.XSD_DATE,
javax.xml.rpc.ParameterMode.IN);//接口的参数
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);//设置返回类型

String temp = "测试人员";
String result = (String)call.invoke(new Object[]{temp});
//给方法传递参数，并且调用方法
System.out.println("result is "+result);
}
catch (Exception e) {
System.err.println(e.toString());
}
}
}
2,直接SOAP调用远程的webservice
这种模式我从来没有见过，也没有试过，但是网络上有人贴出来，我也转过来
import org.apache.soap.util.xml.*;
import org.apache.soap.*;
import org.apache.soap.rpc.*;

import java.io.*;
import java.net.*;
import java.util.Vector;

public class caService{
public static String getService(String user) {
URL url = null;
try {
url=new URL("http://192.168.0.100:8080/ca3/services/caSynrochnized");
} catch (MalformedURLException mue) {
return mue.getMessage();
}
// This is the main SOAP object
Call soapCall = new Call();
// Use SOAP encoding
soapCall.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
// This is the remote object we're asking for the price
soapCall.setTargetObjectURI("urn:xmethods-caSynrochnized");
// This is the name of the method on the above object
soapCall.setMethodName("getUser");
// We need to send the ISBN number as an input parameter to the method
Vector soapParams = new Vector();

// name, type, value, encoding style
Parameter isbnParam = new Parameter("userName", String.class, user, null);
soapParams.addElement(isbnParam);
soapCall.setParams(soapParams);
try {
// Invoke the remote method on the object
Response soapResponse = soapCall.invoke(url,"");
// Check to see if there is an error, return "N/A"
if (soapResponse.generatedFault()) {
Fault fault = soapResponse.getFault();
String f = fault.getFaultString();
return f;
} else {
// read result
Parameter soapResult = soapResponse.getReturnValue ();
// get a string from the result
return soapResult.getValue().toString();
}
} catch (SOAPException se) {
return se.getMessage();
}
}
}
