webservice系列教學（4）-如何調用webservice(pb,java)

web 4.1 使用PowerBuilder調用
    適用版本8.0 需下載Bulletin Web Services Toolkit 4.1
4．2使用java調用
需要下載apache soap。下載地址：http://xml.apache.org/soap/index.html
匯入：
import org.apache.soap.*;
import org.apache.soap.rpc.*;
常式：
import java.io.*;
import java.util.*;
import java.net.*;
import org.w3c.dom.*;
import org.apache.soap.util.xml.*;
import org.apache.soap.*;
import org.apache.soap.encoding.*;
import org.apache.soap.encoding.soapenc.*;
import org.apache.soap.rpc.*;
import org.apache.soap.transport.http.SOAPHTTPConnection;

public class testClient {

    public static void main(String[] args) throws Exception {

        URL url = new URL ("http://192.168.0.4/yundan/service1.wsdl");
//改成你的地址
        SOAPMappingRegistry smr = new SOAPMappingRegistry ();
        StringDeserializer sd = new StringDeserializer ();
        smr.mapTypes (Constants.NS_URI_SOAP_ENC, new QName ("", "Result"), null, null, sd);

        // 建立傳輸路徑和參數
        SOAPHTTPConnection st = new SOAPHTTPConnection();

        // 建立調用
        Call call = new Call ();
        call.setSOAPTransport(st);
        call.setSOAPMappingRegistry (smr);

        call.setTargetObjectURI ("http://tempuri.org/message/");
        call.setMethodName("addNumbers");
        call.setEncodingStyleURI ("http://schemas.xmlsoap.org/soap/encoding/");

        Vector params = new Vector();
        params.addElement(new Parameter("NumberOne", Double.class, "10", null));
        params.addElement(new Parameter("NumberTwo", Double.class, "25", null));
        call.setParams(params);

        Response resp = null;

        try {
          resp = call.invoke (url, "http://tempuri.org/action/Hello2.addNumbers");
        }
        catch (SOAPException e) {
        System.err.println("Caught SOAPException (" + e.getFaultCode () + "): " + e.getMessage ());
        return;
        }

        // 檢查傳回值
        if (resp != null && !resp.generatedFault()) {
        Parameter ret = resp.getReturnValue();
        Object value = ret.getValue();

        System.out.println ("Answer--> " + value);
        }
        else {
            Fault fault = resp.getFault ();
            System.err.println ("Generated fault: ");
            System.out.println (" Fault Code = " + fault.getFaultCode());
            System.out.println (" Fault String = " + fault.getFaultString());
        }
    }
}
