Share code between Automation Client and Server

The Java Automation Client is evolving at the same time as the server side.

But it becomes more and more obvious that there are some classes that should be shared by the server and the client :

• Blob classes
• Properties classes
• DocumentRef classes

We also have some "almost duplicated" classes for the marshaling code.

Moreover, the fact that we now support the concept of business adapter will push users to use the same class on the client and server side.

This task will not be easy to do without breaking anything on the client side API.
