Hi,
Well thanks for the source code that will help greatly. I have however
discoved what I beleive to be a (( BIG )) problem. (not with you code, I
hasten to add....)
Runtime.getRuntime().exec("cd /tmp; mkdir ItWorked");
Reports the following error....
"IOException : cd : not found".
Now I know this is a big problem. My current user setup in Apache is...
user : nobody
group : nogroup
Anymore Ideas out there? Or am I doing something blindingly obvious?
Keith
