  查询服务程序的实现过程:创建Inquiry对象,并设置查询地址;声明FindBusiness对象,并设置查询服务名和相关属性;获得BusinessList对象,然后层层向下查询:BusinessList->BusinessInfo->ServiceInfo->BusinessService->BindingTemplate,最后得到AccessPoint对象,调用getText()方法,就可获得该服务的入口地。得到服务的WSDL之后,可利用WSIF调用这个服务的方法。见如下程序的方法:
  
  public void getServicesURL(){
  try{
  Inquiry inq=new Inquiry();
  inq.setURL("http://huijddn.com/services/uddi/inquiryapi");
  FindQualifiers fqs = new FindQualifiers();
  FindBusiness fb = new FindBusiness();
  fb.setFindQualifiers(fqs);
  fb.setName(new Name("MagazineServices"));//查找服务名MagazineServices的服务
  BusinessList rBusinessList = inq.findBusiness(fb);
  BusinessInfos rBusinessInfos = rBusinessList.getBusinessInfos();
  Vector rBusinessInfoVector = rBusinessInfos.getBusinessInfoVector();
  BusinessInfo rBusinessInfo;
  for (int y =0; y < rBusinessInfoVector.size(); y++)
  {
  rBusinessInfo = (BusinessInfo)rBusinessInfoVector.elementAt(y);
  System.out.println("*********BUSINESS INFO********");
  System.out.println("Attribute BusinessKey: "+rBusinessInfo.getBusinessKey());
  Name rName = rBusinessInfo.getName();
  System.out.println("Name : "+rName.getValue());
  Vector rDesVector = rBusinessInfo.getDescriptionVector();
  Description rDes=null;
  printDescriptionVector(rDesVector);
  ServiceInfos rSerInfos = rBusinessInfo.getServiceInfos();
  Vector rServiceInfoVector = rSerInfos.getServiceInfoVector();
  ServiceInfo rServiceInfo;
  for (int x =0; x<rServiceInfoVector.size();x++)
  {
  System.out.println("*********Service Info********");
  rServiceInfo = (ServiceInfo)rServiceInfoVector.elementAt(x);
  System.out.println("Service Info Name: "+rServiceInfo.getName().getValue());
  System.out.println("ServiceKey : "+rServiceInfo.getServiceKey());
  System.out.println("BusinessKey : "+rServiceInfo.getBusinessKey());
  String magazineServer=rServiceInfo.getServiceKey();
  ServiceDetail rServiceDetail = inq.getServiceDetail(gsd);
  Vector rBusinessServiceVector = rServiceDetail.getBusinessServiceVector();
  BusinessService rBS;
  for (int a=0;a<rBusinessServiceVector.size();a++)
  {
  System.out.println("*****************BUSINESS SERVICE***************");
  rBS = (BusinessService)rBusinessServiceVector.elementAt(a);
  Vector rDesVector = rBS.getDescriptionVector();
  BindingTemplates rBTs = rBS.getBindingTemplates();
  if (rBTs !=null)
  {
  Vector rBTVector = rBTs.getBindingTemplateVector();
  BindingTemplate returnBindingTemplate;
  for (int i = 0; i < returnBindingTemplateVector.size(); i++)
  {
  System.out.println("***********BINDING TEMPLATE*************");
  returnBindingTemplate =(BindingTemplate)returnBindingTemplateVector.elementAt(i);
  Vector rDesVector = returnBindingTemplate.getDescriptionVector();                  AccessPoint rAP = returnBindingTemplate.getAccessPoint();
  java.net.URL url=new URL(rAP.getText());//找到服务的URL地址
  }
  }
  }
  }
  }
  }catch(Exception e){
  e.printStackTrace();
  }
  }
