Navigation Panel using Java Bean Base API

Question

Hi,
I would like to know how do I add the standar navigation panel to my map using the oracle.lbs.mapclient.MapViewer object. I have try different forms which include adding a tile theme layer but its not working. I'm not using the JS API since I want to have an applet.
Thanks in advance.

Hi,
in MapViewer's web page there is a link to some demos. There you can find a few examples of how to use the Java bean with jsp pages.
If you want to implement a simple java (desktop) application, the following code contains the basic information that you need to start the MapViewer object, set the display parameters, and then add some information to generate a map image. In this example, a base map is used to generate the map.
    String url = "http://localhost:7001/mapviewer/omserver";
    try
      MapViewer mapViewer = new MapViewer(url);     // creates MapViewer object
      mapViewer.setDataSourceName("mvdemo");       // sets the data source (must exist in Mapviewer server)
      mapViewer.setMapTitle("MVDEMO base map");           
      mapViewer.setAntiAliasing(true);    
      mapViewer.setImageFormat(MapViewer.FORMAT_RAW_COMPRESSED);
      mapViewer.setDeviceSize(new Dimension(600,475));
      mapViewer.setCenterAndSize(-116.65,38.92,19.2);         // sets the map area
      mapViewer.setBaseMapName("DEMO_MAP");
      System.out.println(mapViewer.getMapRequestString());    // this prints the current map request to be issued
      boolean response = mapViewer.run();      // executes the request
      if (response)
          Image img = mapViewer.getGeneratedMapImage();
         // do something with the image in your Java application
    }catch(Exception ex)
       ex.printStackTrace(System.err);
    }The API java doc (see APIs link in MapViewer's web page) contains a more detailed description of the methods that can be used with the Java bean API.
