Netscape Livewire: file upload

I am developing an application where the user will upload an image file from the browser. The image is to be stored into a database.
The configuration is
browser - netscape navigator 4.0 (beta)
web server - netscape enterprise 2.0 on NT 4.0
database - informix online for workgroups ver 7.12
db connectivity tool - netscape livewire pro 1.x

I have a form with ENCTYPE="multipart/form-data" which has a few text fields and a TYPE=file field.

My problem is that the LiveWire request object submitted by the form with is received as a null object by the server side javascript.

When I debug the application, the debug window shows the data entered by the user in the form, but it cannot be accessed by the standard mechanism i.e.
request.fieldname
syntax.

Everything seems to work fine when the ENCTYPE tag is removed, but I do need it for file upload to work. Without ENCTYPE, only the file name is sent to the server and not the file contents.

All suggestions/solutions are welcome.

Thanks in advance.

Commented:
The ENCTYPE should be multipart/form-data.  Otherwise,
as you say, it will simply send the filename info..

Anyway, although I am not too good on java, the above
enctype will come in on stdin (cin?  tiz on c++ anyway!)
as a mime section (not a correct mime message as it
does not have the right headers..

In perl, and html, here is an example that will save
the file locally:

--html page --

<HTML><BODY>

<FORM ACTION="antest.cgi" ENCTYPE="multipart/form-data">

<INPUT TYPE="file" name=afile><BR>
<INPUT TYPE="submit">

</FORM>

</BODY></HTML>
--  end --

-- perl script --

#!/usr/bin/perl

print "Content-Type: text/html\n\n";
print "<H1>This part is the html outputted to screen</H1>\n";

$line = 0;

read(STDIN, $incoming, $ENV{'CONTENT_LENGTH'});

open (OUTPUT, ">recieved.file") ||
    print "<P> ERROR in opening output file";

print OUTPUT $incoming;

close (OUTPUT);
