Help!! wms and java api

Question

hi!, i`m newie on oracle, and i`m using mapviewer with java api but i have problems with the addWMSMapTheme function:
Object vsp = new Object[]{new String[]{"DATASOURCE", "example"}, new String[]{"antialiasing", "true"}};
mv.addWMSMapTheme("wmstheme","http://onearth.jpl.nasa.gov/wms.cgi?","false","1.1.1","BMNG","default","EPSG:4326","image/jpeg","false","0xFFFFFF","application/vnd.ogc.se_inimage", vsp);
it return a exception (that the object vsp is not define).
does i have to use the xml request?? how can do it??

Hi,
you can use the API which will generate and send the map request to MapViewer. Your vsp parameter looks strange. The following is a sample code that use the MVDEMO data set, just to give you an idea of the definition for vsp parameter.
    mapViewer.setImageFormat(MapViewer.FORMAT_PNG_URL);
    mapViewer.setDataSourceName("mvdemo");
    mapViewer.setCenterAndSize(-70.,44.,20.);
    mapViewer.setMapTitle("WMS");
    mapViewer.deleteAllThemes();
     Object []vsp = new Object[]{new String[]{"DATASOURCE", "mvdemo"}  };
     mapViewer.addWMSMapTheme("wms_theme", "http://localhost:7001/mapviewer/wms",
                              new String[] {"THEME_DEMO_STATES"}, new String[] { "asdf"},
                              "SDO:8265", "image/png","0xffffff", vsp);             
     System.out.println("Current request: " + mapViewer.getMapRequestString());    
     boolean response = mapViewer.run();
     if (response)
          double[] mbr = mapViewer.getMapMBR();
          System.out.println("mbr="+mbr[0]+","+mbr[1]+" "+mbr[2]+","+mbr[3]);
          System.out.println("URL: " + mapViewer.getGeneratedMapImageURL());
      }For you case, make sure the WMS server at http://onearth.jpl.nasa.gov/wms.cgi? is running and accepting requests. I tried a GetCapabilities request to this server, and got an exception message that the system was overloaded and not processing requests.
