        longVec.addElement("72.864761");
        latVec.addElement("19.066985");
        longVec.addElement("72.848969");
        addressVec.addElement("abc");
        addressVec.addElement("wydj");

        for(int j=0;j<latVec.size();j++)
        {                   
            double latlong = Double.parseDouble(latVec.elementAt(j).toString());
            double lonlong = Double.parseDouble(longVec.elementAt(j).toString());

            int lat = (int)latlong*100000;
            int lon = (int)lonlong*100000;
            String addressString = addressVec.elementAt(j).toString();          


            document.append("<location lon='"+ lon +"' lat='"+ lat +"'label='"+ addressString +"' description='"+ addressString +"' />");

        }

        document.append("</location-document>");

        String st = new String(document);

        Invoke.invokeApplication(Invoke.APP_TYPE_MAPS, new MapsArguments(MapsArguments.ARG_LOCATION_DOCUMENT, st));
