Thanks Laurent:

Produces no output?
Implies that hasMoreElements() is false?
Ralph suggested
String[] f = request.getParameterValues(file0);
f[0]
..
f[f.length - 1]
but I can't see how that will access the entry with name file1, file2 etc?
Perhaps all the entries should be named the same (which seems illogical).

Sorry i misread your post, that is the solution to retrieve the values if you have more than one field with the same name. If you have file0 through filen this should work: request.getParameter(file0); .. request.getParameter(filen); if file1 through filen are null against your expectations, I would say something is wrong on the client side.

Re: javascript and servlets.
A better approach would be to name all the fields file instead of
fileX and then us the getParameterValues to get the enumeration of
values taken from the fields named file very simple and
elegant not for (int loop just a plain old while
(enum.hasMoreElements()){ enum.nextElement().}
if your javascrip relies on the field names, you can use the fields ID
instead, because field ID isn't passed as parameter name

I have a form with multiple input name=file0 elements.
The names are generated and range file0..n
I'm trying (and failing) to retrieve the value of the input fields.
String f =;

The remainder appear inaccessible.
In the docs ...webapps/tomcat-docs/servletapi/index.html
I'm warned:
You should only use this method when you are sure the parameter has only
one value. If the parameter might have more than one value, use
getParameterValues(java.lang.String).
However, since each entry within the form has a variant name value,
what parameter should I pass to the getParameterValues method

Re: javascript and servlets.
If your fields are all file uploads, then you probably can't get them through the regular HttpServletRequest.getParameter(). I'm curious though, what do you get from the first element (file0). Is it the file contents? What you need to do is submit the form as multipart form, and process posted boundaries. This article has everything that you'll need: http://www.javaworld.com/javaworld/jw-06-2001/jw-0622-filters-p4.html Don't forget to modify your form like this: form method=post action=/repository/getit name=form enctype=multipart/form-data On Fri, 3 Sep 2004 12:21:52 +0100 , [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: -Original Message- From: Ralph Einfeldt form method=get ... /form the query string can be found in the access log.

That I didn't know.
Thanks Laurent.
Mike/John, I am now getting them via the request.getparameter() call,
Just that I had a problem on the client end.
f = request.getParameter(file0);
while (f != null){
out.println(pfile : + f );
out.println(/p);
// fn[numFiles]=f;
numFiles++;
f =
request.getParameter(file+Integer.toString(numFiles));
System.err.println(Seeking +
file+Integer.toString(numFiles));
}
Is working well.. except for the path being curtailed, just returning the
filename+ext.
