Files and Input Forms

Question

Hello,
I have a form that has a single input form of type "file". I want to write a servlet that, when a file, is selected and the form submitted to be able to get at the contents of the file.
For example, user browses for an XML file and presses the submit form button. Within my servlet I want to be able to access the contents of the xml file that is in the request.
Thanks,

sorry to correct, but if you need the content of the uploaded file in your application, you need the MultiParser object.
Thatfor get the com.oreilly.servlet package (free, use google to find a download site).
The basic code would look like:
MultipartParser Parser = new MultipartParser(request, 50 * 1024); // 50k Filesize Limit
                    Part Part;
                    while ((Part = Parser.readNextPart()) != null )
                        // returns true if the Part is a File
                        if (Part.isFile())
// cast the Part to a FilePart to handle it
                            FilePart FilePart = (FilePart) Part;
                            String FileName = FilePart.getFileName();
                            String ContentType = FilePart.getContentType();
long size = FilePart.writeTo(FileToUpload);
