Hi Cat,
I think the problem is how you are configuring the layer to be used in
the application. The easiest thing to way to start is to use the
default OpenMap application, configured with the openmap.properties
file. You'll want to add an entry for the EarthImagePlugIn in the
openmap.layers property with some keyword you choose. Then, using
that keyword to scope the properties for the layer, add them to the
properties file, too. For instance, if I choose earthImage as my
keyword, I'd have properties like:
earthImage.prettyName=Earth at Night
earthImage.class=com.bbn.openmap.plugin.earthImage.EarthImagePlugIn
earthImage.image=/data/geoImages/Earthlig.jpg
If you want to do this programmatically, I'd create a PlugInLayer and
then set the properties on it:
PlugInLayer pil = new PlugInLayer();
Properties earthImageProps = new Properties();
earthImageProps.put("prettyName","NasaBlueMarblePlugIn");
earthImageProps
.put("plugin","com.bbn.openmap.plugin.earthImage.EarthImagePlugIn");
earthImageProps.put("image","/data/geoImages/Earthlig.jpg");
pil.setProperties(earthImageProps);
(You don't need to set the class property for the layer because it's
already instantiated at this point)
Then, add the PlugInLayer to the MapHandler or the BasicMapPanel.
Follow the model in SimpleMap2 for configuring an OpenMap app, and
make sure you use the LayerHandler too.
Hope this helps,
Don
