4.1 使用PowerBuilder调用    适用版本8.0 需下载Bulletin Web Services Toolkit 4.14．2使用java调用需要下载apache soap。下载地址：http://xml.apache.org/soap/index.html导入：import org.apache.soap.*;import org.apache.soap.rpc.*;例程：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);         // 创建传输路径和参数        SOAPHTTPConnection st = new SOAPHTTPConnection();         // 创建调用        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;        }         // 检查返回值        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());        }    }}
