Did you read this thread: wping
It’s actually a co-incidence that you post this today, as I was testing the same this afternoon. The script was working to the point of the doc refresh which was NOK, but then I left for the day.
I had no problems with running it though - we are Windows 2000 / Tom-Apache.
I am also testing jsp scripts that do doc refreshes.
