When i look into the location for file to upload to ftp, it exists at that location.Please help me with the cause for this exception and a resolution will be highly appreciated.

Welcome to the Ranch

Please check that the file is accessible and that you have read permission on it. If you try to read a write-only file, or the file is locked by another application, for example, you suffer the same sort of exception.

Hi Campbell,

Thanks for your quick reply.
I tried to find the file permissions and found that it has both read and write permissions.
I am getting the same logs.

The topic still can be seen in original forum (where you've started it - I guess that is 'Beginning Java'), however, when you open the post, you can see in which forum you are by taking a look at top of the first post (currently, the topic is in 'Java in General' forum).

I hope this helps.

Hi,

If anyone can please help me with this issue in this forum.
Any help will be highly appreciated.

Thanks,
Kamal

I don’t know myself.
I presume your file is not in use by any other programs? How are you identifying the file? Are you using a file chooser? Can you list the contents of the remote directory?
Apart from that, don’t know. And please don’t keep reminding us of the problem; such reminders do not produce quicker answers.

Hi Kamal,

Did you get any solution for this issue? I have also same issue. But I am getting the same exception when I use SftpClient.ls() method. It works some times and some times it will not work.
Please let me know, if you have any solution.
