Cannot connect to ORB

[Rick Bos]

        I have created a simple Entity bean called Demographics.

        I have deployed the application as an ear file in orion.

        I created a java program to attempt to access this entity bean.

        When I come to the line 

        Object homeObject = context.lookup("java:comp/env/Demographics");

        I get this error :

        Communication error: Error accessing repository: Cannot connect to
ORB


        Also does anyone have a sample application working with the Ingres
database ?


        Any help would be appreciated.
