VB-Java Interaction?

I have got a legacy application in VB.
I have got a portal in Java.
My VB application needs to be network enabled.That means,whatever changes I make to my VB database(MS-Access) should be reflected to my website database(SQL Server) and vice-versa.
What it essentially means that clients who log in to my VB application should get current database information.

What could be the solution?How to connect my VB and Java applications so that they would be updating databases on client side as well as web?
Can CORBA be a solution?Or something else?
