Hello Everybody,

Continuing from the following topic :
http://www.experts-exchange.com/Programming/Programming_Languages/Java/Q_21107473.html

When I pass argument in the form:

InputStream in = new URL("ftp://username:password@domain.com/file.ext").openStream();

I get exception as :

java.io.FileNotFoundException:/opt/home/testdir/test.txt :  A file or directory in the path name does not exist.

File permissions on test.txt are  -rw-r--r--

and I am connecting as authorized user not anonymous user.

Thanks,
Paluindian

To clarify more, when I put this URL URL("ftp://username:password@domain.com/file.ext") in  Windows Explorer I get folder path created in Windows Explorer but I can not click on those folders and access files inside it. Sorry for the confusion for early part, I thought I could access it...I was just very happy to know FTP URL access to the file.

Through Windows Explorer I get message :

" Windows can not access this folder, make sure you have typed folder name correctly and that you have permission to access this folder"

Details:

530 user Anonymous unknown


Is this something to do with permissions? Machine is not set to access via FTP or something?

Thanks in advance,
Paluindian

It seems that the ftp server thinks you are logging in with Anonymous and while this is not allowed or that you are using an invalid username (This is in most FTP daemons handled as an Anonymous login). So it looks to be a permissions problem on the serverside or you didnt inserted the right username/password combination to login. So i think you should have a look at those settings.

Can you post the url you're *actually* using (obviously change the username and password parts)?

I'm using following URL:

ftp://username:password@machinename/opt/home/testdir/test.txt

If I have understood correctly objects your question, you meant manually accessing file:
I use:

ftp machinename
username (prompted) : username
password (prompted) : password
cd /opt/home/testdir
get testdir.txt

Thanks,
Paluindian

>>ftp machinename

Is that being done directly on the ftp host, i.e. on the same machine as 'machinename'?

Hey all...

I tried this borrowing my colleagues userid/password...it is working. I guess some problem with my account. I could access it with above commands from the windows client but not programmatically. But anyway...I do not have to use my login...because others are going to use this automation...if there userid works...it works for me ;-)

Thanks ya all,
Paluindian

paluindian, that it locally works most likely means it has only local rights and not external, but nice to see you solved it :). My suggestion is always to try multi accounts if one account is not working, because it might be possible that it's an userright issue which is not a programming fault.
