程序片段如下，执行到

import java.util.*;
import javax.xml.registry.*;
import javax.xml.registry.infomodel.*;

public class JAXRQuery {
  Connection connection = null;

  public JAXRQuery() {}

  public static void main(String[] args) {
    String queryURL =
        "http://127.0.0.1:8080/registry-server/RegistryServerServlet";
    String publishURL =
        "http://127.0.0.1:8080/registry-server/RegistryServerServlet";

    String queryString = "Coffee";
    System.out.println("Query string is " + queryString);
    JAXRQuery jq = new JAXRQuery();
    jq.makeConnection(queryURL, publishURL);
    jq.executeQuery(queryString);
  }

  public void makeConnection(String queryUrl, String publishUrl) {

    String httpProxyHost = "";
    String httpProxyPort = "";

    Properties props = new Properties();
    props.setProperty("javax.xml.registry.queryManagerURL", queryUrl);
    props.setProperty("javax.xml.registry.factoryClass", "com.sun.xml.registry.uddi.ConnectionFactoryImpl");
    props.setProperty("javax.xml.registry.http.proxyHost", httpProxyHost);
    props.setProperty("javax.xml.registry.http.proxyPort", httpProxyPort);

    try {
      // Create the connection, passing it the
      // configuration properties
      ConnectionFactory factory = ConnectionFactory.newInstance();
      factory.setProperties(props);
      connection = factory.createConnection();
      System.out.println("Created connection to registry");
    }
    catch (Exception e) {
      e.printStackTrace();
      if (connection != null) {
        try {
          connection.close();
        }
        catch (JAXRException je) {}
      }
    }
  }

  public void executeQuery(String qString) {
    RegistryService rs = null;
    BusinessQueryManager bqm = null;

    try {
      // Get registry service and query manager
      rs = connection.getRegistryService();
      bqm = rs.getBusinessQueryManager();
      System.out.println("Got registry service and query manager");

      // Define find qualifiers and name patterns
      Collection findQualifiers = new ArrayList();
      findQualifiers.add(FindQualifier.SORT_BY_NAME_DESC);
      Collection namePatterns = new ArrayList();
      namePatterns.add("%" + qString + "%");

      // Find using the name
      BulkResponse response =
          bqm.findOrganizations(findQualifiers, namePatterns, null, null, null, null);
      Collection orgs = response.getCollection();
……（以下省略）

可以确定在Xindice数据库内已经存在该org的记录，但是执行到这里orgs的记录数为0，请高手指点
