Hi, I am working on a CORBA based distributed application. The available
services are a Collection service, which writes data to the persistent
medium, Oracle 8i database, and a Reporting service which reads data from
the database. The Reporting service is written in Java and I am using JDBC
abstraction to connect to the database from the Reporting service.

The Reporting service needs to show realtime information to the user whenever
a new record is added to the database table by the Collection service. Is it
possible to subscribe my business objects in the ReportingService as database
table listeners using JDBC so that i get notified whenever a new record is
added to the table.
Just wondering how expensive polling the database table will be if this is
not supported !!!!
