I have a system developed in Power Builder. Now my requirement is to make it web enabled and I don't want to rewrite the buisness logic already written in Power Builder. So how can I use Power Builder object in my application written in Java using CORBA as midlle tier? Is it possible?

I'm assuming that what you want is to publish your application as a service using CORBA.

The simplest way to do this is simply to implement a facade pattern or a proxy pattern (it's an issue of state in the server) to hide your application behind a set of business methods. There are then a few ways to couple the interface to your system: you can directly call your code base to accomplish the task; or you can re-send the method calls to your application using the pre-existing public entry points (be it native calls, or a network request).
