Upload multiple files WITH correct pairs of form fields into Database

Question

In my form page, I would like to allow 3 files upload and 3 corresponding text fields, so that the filename and text description can be saved in database table in correct pair. Like this:
INSERT INTO table1 (filename,desc) VALUES('photo1.jpg','happy day');
INSERT INTO table1 (filename,desc) VALUES('photo2.jpg','fire camp');
INSERT INTO table1 (filename,desc) VALUES('photo3.jpg','christmas night');
However, using the commons fileupload, http://commons.apache.org/fileupload/, I don't know how to reconstruct my codes so that I can acheieve this result.
if(item.isFormField()){
}else{
}I seems to be restricted from this structure.
The jsp form page
<input type="text" name="description1" value="" />
<input type="file" name="sourcefile" value="" />
<input type="text" name="description2" value="" />
<input type="file" name="sourcefile" value="" />The Servlet file

}Can anyone give me some code suggestion? Thx.

When one hits the submit button - I then get a 404 page error.What is the apaches(?) error log saying? Mostly you get very useful information when looking into the error log!
In any case you may look at how you are Uploading Multiple Files with mod_plsql.
