On Windows 2000 at least, it seems that it uses the value of environ TMP (or TEMP, I have both set to same) to get a base directory.
The directory Jetty__8080___ should contain your jsp's
dur.. its in the same place as 3.0.0:
C:\Documents and Settings\matt\Local Settings\Temp\Jetty__80___
I wrote that dur before I saw your reply.. so the dur was to myself, not you.
Thanks for your help again though --
