import org.apache.xmlrpc.client.XmlRpcClient;
import org.apache.xmlrpc.client.XmlRpcClientConfigImpl;
import org.apache.xmlrpc.client.XmlRpcCommonsTransportFactory;

public class BugCreator2 {
   public static void main(String s[])
      throws MalformedURLException, XmlRpcException {

    HttpClient httpClient = new HttpClient();
    XmlRpcClient rpcClient = new XmlRpcClient();
    XmlRpcCommonsTransportFactory factory = new XmlRpcCommonsTransportFac=
tory(rpcClient);
    XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();

    factory.setHttpClient(httpClient);
    rpcClient.setTransportFactory(factory);
    config.setServerURL(new URL("http://URL/bugzilla/xmlrpc.cgi"));
    rpcClient.setConfig(config);

    // map of the login data
    Map loginMap = new HashMap();
    loginMap.put("login", "username@abc.com");
    loginMap.put("password", "*********");
    loginMap.put("rememberlogin", "Bugzilla_remember");

    // login to bugzilla
    Object loginResult = rpcClient.execute("User.login", new Object[]{log=
inMap});
    System.err.println ("loginResult=" + loginResult);

    // map of the bug data
    Map bugMap = new HashMap();

    bugMap.put("product", "Demo");
