Salut!
I think you need to do an url.setDoInput(true) to fix the problem. The
javadoc of URLConnection says:
"A URL connection can be used for input and/or output. Set the DoInput flag
to true if you intend to use
the URL connection for input, false if not. The default is true unless
DoOutput is explicitly set to true, in
which case DoInput defaults to false."
Since you do set the DoOutput flag to true its normal to get an exception.
When you try to get the InputStream it is supposed to throw you an
IOException. FileNotFoundException is an IOException but it's kinda strange
to throw that particular one from an URLConnection !!!!
Hope this helps,
