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); } } }
