I am writing a HTML which basically selects a file to be parsed (eventually I am calling a servlet). This works fine with :

<input type=file name=uploadfile value='SelectFile'>

I would like to store the result in a directory as a .txt file. I am not able to select a directory where from my HTML. Does anyone have an idea how to do it either inHTML or JSP..
Thanks

In just HTML no, and in JSP I don't think so.
Heres a link that may be handy

Incidentally you cant set the value of a File tag.

for security reasons you cannot preset the  contents of a file input type. You also cannot change its value using javascript. This is to prevent websites uploading files from your computer that you haven't said they could upload.

You may be able to do it using a java applet or activex component or some other plugin.

If the servlet that's processing your file could send the results back with a mime-type other than text, so that the browser asks the user what to do with it, like when you download software, that might be one way to go.

Hi,

  Are you asking how to save the uploaded file to a particular directory on the server?  Or how to save a file (not necessarily the uploaded file) to a directory on the user's machine?

Hi Arschie,

maybe you can adapt this:

function doit(contents)
{
  var contents = document.a.c.value;
  var txtFile = document.a.b.value;
  var fso, f1, ts, s
  var ForWriting= 2;
  fso = new ActiveXObject("Scripting.FileSystemObject")
  ts = fso.OpenTextFile(txtFile, ForWriting)
  ts.WriteLine(contents)
  ts.Close()
}

//-->
</script>
</head>
<body>
<form name="a">
<input type="file" name="b">
<textarea name="c"></textarea>
<input type="button" value="do it" onclick='doit()'>
</form>
</body>
</html>

I am not able to run this.
It's giving error on page.

Probably it is due to Active X

Hi,
   The above will work only if:
1) you are running in a windows environment and
2) you have Scrrun.dll in the windows\system32 folder
