If the class does not implement one interface (or if it implements more than one interface), the assembly editor will not offer you the option to generate the bridge component.

To make use of the RJCB technology with DTJCB, you create and build the bridge for a "server" component and then add the code to a "client" component for accessing the "server" through the bridge.

As long as they continue to be the major players in component interoperability, there'll be a need to bridge the gap between the two technologies.
