Jan,
The bridge is used to intercept calls from a oda and the
org.eclipse.datatools.connectivity.oda.dataSource extension point is the
runtime portion of an oda.
You need to implement the
org.eclipse.datatools.connectivity.oda.design.ui.dataSource
extension point for the gui part. Take a look at the oda articles on
birt-exchange.org

Jan,
If you are looking to just extend the jdbc plugin, so your oda shows up
in the plugin, take a look at the sampledb driver plugins.
org.eclipse.birt.report.data.oda.sampledb.ui - for the ui and
org.eclipse.birt.report.data.oda.sampledb - for the runtime driver.
This driver just extends the jdbc oda and can be checked out of cvs.

Jan,
Try
:pserver:anonymous@dev.eclipse.org:/cvsroot/birt
We currently do not have anything in the book about this, but once you
download the code you will see it is pretty simple. If you need help
send me an email.

Jan,
I am somewhat confused The driver bridge should not be affecting your
ODA at design time, only runtime.
BTW I am sending you the two plugins in email.
