Try using the parse(HttpServletRequest req) method.
The returned FileItem objects have a method "isFormField()" with
returns true if the particular FileItem represents a field in a
form which is not a file (seems kind of silly, since it's a
"FileItem" class, yet it's representing something that's not a file).

List l = fileUploadInstance.parse(req);
Iterator it = l.iterator();
FileItem item = null;
while (it.hasNext()) {
  item = (FileItem)it.next();
  if (item.isFormField()) {
     // do processing for your fields
  }
  else {
     // do processing for your file
  }
}

I would personally like to see an HttpServletRequest implementation
provided which would take the original request, pass it to a FileUpload
instance for parsing, and process the returned FileItem instances so that
things like "getParameter()" and so forth would work properly.

(hmm.... maybe i should just write that class).

Subject: COMMONS UPLOAD QUESTION "request.getParameter()" 


I have been searching the Internet for a practical Java-based uploading 
solution that is standardized. I have found that there are many Java apps
and tools 
that people have built for this purpose but I find that each have their
short 
falls and must be customized to perform my tasks. My tasks are not 
complicated at all, but apparently there is no information on how to perform
these task 
in the JavaDocs or even newsgroups. Here is what I am looking to do:

I need to input the fields from this for into my database which is perfectly

normalized.  
--------------------------------------------------------------------------
upload.jsp
--------------------------------------------------------------------------
<HTML>
<HEAD>
<META http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</HEAD>
<BODY style="font-family: Arial, Helvetica, sans-serif;">   
    <FORM method="POST" action="add_output.jsp"
encrypt="multipart/form-data" 
>
<TABLE align="left">     
        <TR>
            <TD>
            AUTHOR <INPUT type="text" name="author" size="20" maxlength="50"

value=""></TD>           
        </TR>
        <TR">
            <TD>
            ARTICLE SHORT DESCRIPTION <INPUT type="text" 
name="shortDescription" size="30" maxlength="100" value=""></TD>
        </TR>
        <TR>
            <TD>
        ARTICLE LONG DESCRIPTION <INPUT type="text" name="longDescription" 
size="30" maxlength="120" value=""> *MAY BE NULL</TD>
        </TR>
        <TR>
            <TD>
            ARTICLE CONTENT <TEXTAREA name="articleContent" rows="20" 
cols="80"></TEXTAREA></TD>
        </TR>
        <TR>
            <TD>
            <INPUT type="FILE" name="FILE1" size="50"></TD>
        </TR>
        <TR>
            <TD>
            <INPUT type="submit" value="Insert" onClick=""><INPUT 
type="Reset"></TD>
        </TR>
    </TABLE>
    </FORM>
</BODY>
</HTML>
--------------------------------------------------------------------------
Here is the catch. I want to input the text fields directly in to their 
appropriate fields in the database but I want the file field to grab the
file name 
and input that in the newly inputted row. I also need the file to uploaded
to 
a file folder on my server. I know to pull the file name to input it in the 
database I need to use the getName() method. My problem is in the fact that
I do 
not know which method I need to use to parse the other fields in my form. On

my other forms for inputting info into my database I use JSP and I use the 
request.getParameter. As you know this does not work with the multipart 
encryption. In the JavaDocs it does not directly say which method should be
called to 
parse this information. I chose commons specifically because it had a
multipart 
parser in it. I also like the fact that it is somewhat standardized. I need 
to make sure that I do this right because I find that some many people on
the 
Internet write bad code and I would perfer not to fall into that. I like to 
build most of my stuff in JSP and it is easy to change into servlets if I
need 
to. I have tried a few other methods but I find them very sloppy. I tried
the 
3-Step approach. Where you have a data input JSP which then goes to another
JSP 
which parses the form and inputs the data into the database then calls the
row 
that the data is in and places that info into a hidden field. Then that page

displays the file input box for the user to select the file. Then once that 
form is submitted to the next JSP document it, in theory, is supposed to
find 
the field in the database to insert the file name in the appropriate field
and 
upload the document to a file on the server. I would appreciate it if you
can 
steer me in the right direction or send me a snippet, or link to somewhere
that 
documents this.

Thank you very much,
