    vBilling = "0";


    URL strBilling = new URL("http://192.168.1.2/cvp/wsclient.php?id=" + strDataBill);


    URLConnection hpCon = strBilling.openConnection();
    int len = hpCon.getContentLength();


    if (len > 0)
    {
      BufferedReader in = new BufferedReader(
        new InputStreamReader(strBilling.openStream()));
      vBilling = in.readLine();

    }


    System.out.println("Billing : " + vBilling);
  }


  public void doAction(String name, ActionElementData actionAPI)
    throws AudiumException
  {

Hi, Are you getting a compilation error or a runtime error? Can you post more information about the error message?

If it's a run time error, look in the VXML Server error log.

One thing that's wrong with your java code is that if you are doing string comparisons, you can't use ==  (that's just for number comparisons or comparing to null).

With strings, you must use the method equals or equalsIgnoreCase

  strVar.equals("1")
