Perhaps you have build your application with a NW04<b>s</b> IDE and try to run it on a NW04 server?

Hi Armin

I think that is the problem as I'm using NWDS 7.0 release and my server is NW04 version.

Thanks for the help

Definitely, the mentioned class (actually, interface) is part of WD NW04s functionality.
