Webservice调用方式：axis，soap

Webservice调用方式：axis，soap

java调用webservice， 可以首先根据wsdl文件生成客户端， 或者直接根据地址调用， 下面讨论直接调用地址的两种不同方式：Axis和Soap， soap方式主要是用在websphere下

axis方式调用

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 userName= "开发人员";

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

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

}

catch (Exception e) {

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

}

}

}

soap方式调用

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();

}

}

}

Parameter soapResult = soapResponse.getReturnValue();

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