⑴ 如何打開wsdl文件
webservice的發布一般都是使用WSDL（web service descriptive language）文件的樣式來發布的，在WSDL文件裡面，包含這個webservice暴露在外面可供使用的介面。
注意，以下的代碼並沒有經過真正的測試，只是說明這些情況，不同版本的Axis相差很大，最好以apache網站上的例子為准，這里僅僅用於說明其基本用法。
1,直接AXIS調用遠程的web service，直接調用模式如下：
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";
//直接引用遠程的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裡面描述的介面名稱
call.addParameter("userName", org.apache.axis.encoding.XMLType.XSD_DATE,
javax.xml.rpc.ParameterMode.IN);//介面的參數
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);//設置返回類型
String temp = "測試人員";
String result = (String)call.invoke(new Object[]{temp});
//給方法傳遞參數，並且調用方法
System.out.println("result is "+result);
}
catch (Exception e) {
System.err.println(e.toString());
}
}
}
2,直接SOAP調用遠程的webservice ，這種模式很少用，但是網路上有人貼出來，也轉過來 ：
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();
}
}
}
