調用webservice，可以首先根據wsdl文件生成客戶端，或者直接根據地址調用，下面討論直接調用地址的兩種不同方式：axis和Soap，soap方式主要是用在websphere下

axis方式調用：

 

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";

                     Service service = new Service();

                     Call call = (Call) service.createCall();

                     call.setTargetEndpointAddress(endpoint);

                     call.setOperationName("addUser");

                     call.addParameter("userName", org.apache.axis.encoding.XMLType.XSD_DATE,

                                   javax.xml.rpc.ParameterMode.IN);

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

                     call.setUseSOAPAction(true);

                     call.setSOAPActionURI("http://www.my.com/Rpc");

                     //Integer k = (Integer) call.invoke(new Object[] { i, j });

                     //System.out.println("result is  " + k.toString() + ".");

                     String temp = "測試人員";

                     String result = (String)call.invoke(new Object[]{temp});

                     System.out.println("result is "+result);

              }

              catch (Exception e) {

                     System.err.println(e.toString());

              }

       }

}

soap方式調用

調用java生成的webservice

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();

       }

    }

}

返回一維數組時

Parameter soapResult = soapResponse.getReturnValue();

String[] temp = (String[])soapResult.getValue();

 

調用ASP.Net生成的webservice

private String HelloWorld(String uri, String u) {

              try {

                     SOAPMappingRegistry smr = new SOAPMappingRegistry();

                     StringDeserializer sd = new StringDeserializer();

                     ArraySerializer arraySer = new ArraySerializer();

                     BeanSerializer beanSer = new BeanSerializer();

                     smr.mapTypes(Constants.NS_URI_SOAP_ENC, new QName(

                                   "http://tempuri.org/", "HelloWorldResult"), String.class,

                                   null, sd);

                     smr.mapTypes(Constants.NS_URI_SOAP_ENC, new QName(

                                   "http://tempuri.org/", "temp"), String.class,

                                   beanSer, beanSer);

 

                     URL url = new URL(uri);

                     Call call = new Call();

                     call.setSOAPMappingRegistry(smr);

                     call.setTargetObjectURI("urn:xmethods-Service1");

                     call.setMethodName("HelloWorld");

                     call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);

 

                     Vector soapParams = new Vector();

                     soapParams.addElement(new Parameter("temp", String.class, u, null));

                     call.setParams(soapParams);

 

                     Response soapResponse = call.invoke(url,"http://tempuri.org/HelloWorld");

 

                     if (soapResponse.generatedFault()) {

                            Fault fault = soapResponse.getFault();

                            System.out.println(fault);

                     } else {

                            Parameter soapResult = soapResponse.getReturnValue();

                            Object obj = soapResult.getValue();

                            System.out.println("===" + obj);

                     }

              } catch (Exception e) {

                     e.printStackTrace();

              }

              return null;

       }
