File Upload

[ruba sampath]

Hi

I am using "multipart/formdata" in my JSP page to reterive the file as an object. But i am using text fields as well as check box, radio button in my form. After submitting my form only the upload file contain the value. Othe fields are getting null. I think this is because of enctype. How to resolve it to get all the fields value slong with file type values in my servlet.

Thanks

The exact value for enctype is "multipart/form-data", and you should use type="file" for the input tag. Here is an example:

<form method="post" action="UploadServlet" enctype="multipart/form-data"> Select file to upload: <input type="file" name="dataFile" id="fileChooser"/><br/><br/> <input type="submit" value="Upload" /> </form>

Hi

Thanks for the sample. I am already doing like this only. but the problem here is i am using text as well as checkbox in my form. i m not getting value for that if i use request.getParameter(), because i m using multipart/formdata in my form. HOW TO RESOLVE THIS?

THANKS.

Check out Apache Commons FileUpload.

request.getParameter() returns null for multipart/form-data, so you have to retrieve the value from the FileItem object instead. Here is an example:

			while (iter.hasNext()) {
				FileItem item = (FileItem) iter.next();

				if (!item.isFormField()) {
                                        // this item is file upload field
				} else {
                                        // this item is regular field
					String fieldName = item.getFieldName();
					if (fieldName.equals("field_name")) {
                                              fieldValue = item.getString();
                                        }
                                }
                        }
