Re: Problem with urlConnection

[Jill Stephenson <ji...@dstc.qut.edu.au>]

I remember having this problem a while back and if I remember 
rightly it was because there was no doPost in my servlet.  I 
think setting doInput to true means use POST rather than GET.

Also you might want to check the contents of your url string 
as the file name in the exception doesn't look like it is 
constructed correctly.
