Corba logging

[Matthias]

Hello,

I'm new to Corba and have some questions.
I have a given project that uses the Borland VisiBroker architecture. I
have to implement an instructors place to monitor all events that were
made by a trainee working with the given project.
Is there a way to log all corba calls made in this given project with
java without changing anything in the exsiting code? Or can I register
as an application that gets all corba calls from the other application?
Or log only the content of the message call will help me too. The only
condition is to not change the existing code of the given project.
I hope you could help me.

The given project and my instructors place are implemented in Java with
the Borland Corba.

Regards,

Matthias
