Hi John,
Sure, you can do this with any layer. For shape files, you have
several options - you can create a ShapeLayer and set properties on it
that give information about where the shape files are (they can be
URLs, too), or you can programmatically create a SpatialIndex object
and set it in a ShapeLayer.
You can also use the com.bbn.openmap.dataAccess.shape package
components and get the OMGraphics directly, or use the
com.bbn.openmap.plugin.esri plugin components.
You'd want to get the LayerHandler in App 1 and add the layer to it,
giving it an index from the top of the map.
The thing is, all layers are created dynamically, it's just that they
are usually created at startup. I'd bet you could even create the
layer in App 2 and send it to App 1 using RMI.
Hope this helps,
- Don
