[JSP] Obtaining a set of array values from a enctype multipart form.

A checkbox will have multiple values if the user checks more than one option. I am trying to retrieve the array of checked values.

Previously, without the enctype multipart, a getParameterValues() would have done the job.

I am using enctype multipart because there's a file upload option involved. I am using the Apache FileUpload API.

Logic :
I did a check if it is a form field, and then as long as the form field name matches the name of the checkbox 'genreList' , it will keep extracting the checkbox parameters out.

The checkbox params are then inserted into a ArrayList for further manipulation.

However, my current method of extracting the multiple checkbox values doesn't work.

Any help is very much appreciated

Relevant HTML code :

Code:

<form  action="GetData.jsp" method="post" enctype="multipart/form-data">

<!--Normal Form Fields -->
<td>Release Date</td>
<td><input type='text' size=30 name='date'></td>

<td>Apple</td>
<td><input type='text' size=30 name='apple'></td>

<!-------------------------- Checkbox ---------------------------------------->
<td>Genre:</td>
<td><input type='checkbox' name='genreList'> " + genreName + " </td>

</form>

Relevant JSP code:

Code:

String getRelDate = "";
String getApple = "";

      try{ 
         // Parse the request to get file items.
         List<FileItem> items = upload.parseRequest(request);

         // Process the uploaded file items
         Iterator<FileItem> i = items.iterator();

         while ( i.hasNext () ) 
         {
        FileItem fi = (FileItem) i.next();
        
if ( fi.isFormField () ){
fi.getFieldName().equals("date");
getRelDate = fi.getString();

fi.getFieldName().equals("apple");
getApple = fi.getString();

// get params from checkbox named 'genreList'   
// This doesn't work. 
fi.getFieldName().equals("genreList");
String getGenre = fi.getString("genreList");
// adds each checkbox param to ArrayList 'genreTick' 
genreTick.add(getGenre);
}


    }
}
