Hi
I am trying to get the demo Dynatable running but I keep getting the
following error message on the server side:
Connection received from localhost:52226

On the client side the error message window reads:
An RPC server could not be reached.
I have strated the server with "Run as --> Web application" but also
with "Debug as --> Web application"
Does anybody have an idea why this error occurs? Any hint is
appreciated.
Thanks Tobias
