hi there!
i'm new to the gdata api an wanted to try it out. in my particular
case i want to come along with java and read the basics for this api
at http://code.google.com/support/bin/answer.py?answer=78455&topic=12022;
well i tried out the code but get an error :
Sure the authentication must be done by using https etc. i dont know
what actually goes wrong i thought the api will handle the
authentication process.
