Hi Annick,

The first case should work, but there are conditions under which it will
fail. However, before we can determine what's going wrong, we need a better
understanding of what you are doing.

1. Are you establishing the connector through the dialogue and prior to
login, post login, manually, or what?
2. When you say it doesn't work, what actually happens? If you get an
exception, a detailed stack report will help enormously.

One of the greatest difficulties with name/class connectors is handling new
versions of the class. The connector creates a mapping between the objects
so identified at the time of login. A new class version has a different
object identifier and is not nor will it be mapped to the client class.

Absent a new class version, updating the client class' methods from the
server class should work.
