How can i recevice a file from server through web service or any other
method with a javascript code at client side??? The file list is
displayed and on click of button that particular file assosiated with
that button should be retrieved to the client from server.

You say retrieved. I assume then that you mean to have the client
download the specified file from the server?

If so, then simply do one of the following:

1. Provide anchors with the files' URL as the href attribute, or
2. If you want a button to initiate download then there are two
options:
 A. Create a form for each file with the file's URL set as the action
attribute, or
 B. Create a button for each file with the following onclick handler:
 <input type="button" value="File1"
onclick="document.location=file1_url;"/>
 Simple replace File1 with the filename and file1_url with the file's
url.

If downloading the file was not your goal, please let us know.
