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;

?????? }
