you have an error starting up a smart client?
But the log you gave us:
2007-09-17 15:16 http-8080-1 ERROR com.servoy.j2db.util.Debug Throwable

is not an smart client error but a WebClient (that also seems a bug somewhere to me, nullpointer shouldn’t happen)
But this is not the smart client
So what is the exact error you get when you startup the smart client on both ends, The Server and the Client?
