iApp objects are stored in their own folders. By default, you will be connected to the "/Common" folder and when you query any objects, it will list the objects in that folder only. You can change the behavior of the calls to return all folder items as well as child folder items by calling the System.Session.set_recursive_query_state() method and setting the value to STATE_ENABLED. Off the top of my head, I can't remember the names for the folder paths for iApps but it does also contain the iApp service name itself. Here's some procedures that may help you
1. Query all pool objects on the system
1.a Set the active folder to "/" with the System.Session.set_active_folder() method.
1.b Set the recursive query state to STATE_ENABLED with the System.Session.set_recursive_query_state()
1.c Make a call to the LocalLB.Pool.get_list() method. It will return fully qualified object names (ie. /Common/mypool). You should see your iApps pools in there.
1.d make sure you undo any changes you want to the query settings.
2. Query list of all iApps
2.a The Management.ApplicationService.get_list() will return the names of all your deployed iApps (ie. Application Services).
From 2 and 1 you should be able to programmatically set your active folder to the iApp you are concerned with and then make all iControl calls to get the objects contained in that iApp.
Hope this helps...
