Any help is appreciated
java.io.File only works with the local harddisk. Use java.net.URL instead for network resources:
new URL("http://192.106.100.35/Recorded%20files/536.wav");
for this to work, you need a server on 192.106.100.35 which supports the HTTP protocol and which exposes the file as /Recorded%20files/536.wav
Other options are NFS or SMB (to mount a remote file system on the local computer; afterwards, you can use File again).
Short version is you can't do that at all.
Javadoc here I'm guessing maybe this is a windows share? But how you get at it depends on the server side. If you can actually mount the remote device e.g.(NFS/Samba/CIFS) then you could salvage this approach. But if it is like an HTTP server you are completely barking up the wrong tree.

Our users are seeing TCP resets which they believe is originating from our server or an intermediate device in between.
On our server application log, I can see the error which tallies with the time(s) they are seeing the resets.

My question is: Is it our application that is causing the resets or is it the client?
Apologies for the lack of technicality around this question.
The problem is in the client.
There are two possibilities:
1) Client is not sending all data.
2) Client putting a wrong value content-lenght header.

problem with myeclipse, I have removed all jar files from myproject(right-click)>>properties>>java Built Path>> libraries.
Then I added jar files directly to lib folder of myproject.
It solved my problem.

I believe you've had some clients being served a request at this moment. If it does not happen every time you can safely ignore it.
You can even place a Filter around your servlet and try catching the exception so that the logs are not polluted.

Spring's file-upload stuff uses Apache Commons FileUpload under the covers. You'll need to download that and include it in your app. This, in turn, also requires Apache Commons IO, so youi'll need that also.
you missed to add jar "common file upload" or "file io" or added older verson of jar
good example of file upload is http://hmkcode.com/spring-mvc-upload-file-ajax-jquery-formdata/
thank you
