Hi Ruben,
You'll want to define a Layer object to handle the things you want to
draw on the map, instead of rendering directly on the MapBean. You
can find some layer examples in the com.bbn.openmap.layer.examples
package, or take a look at the com.bbn.openmap.layer.DemoLayer class.
You'll want to use the OMGraphics in your layer to represent your
object (not EditableOMGraphics, those are for the drawing tool). Your
layer gets added to the application, and your objects will appear on
the map. You can use the default OpenMap application and add your
layer in the openmap.properties file (look for openmap.layers
property). Or, you can look in that examples directory and follow the
simple2 example.
Hope this helps,
Don
